These are some things I learned from the interesting genetic videos: (First Video: Genetics: Where do your genes come from?) - That you have 2 sets of 23 chromosomes - One set of chromosomes are from your mom, and the set are from your dad - That almost all the chromosomes you get from you dad, you get from your mom (and together both of the chromosomes form homologous chromosomes) - When sperm and egg cell join together they create a single cell that has two full sets of chromosomes, one from your moms side and one from your dads. - That one cell will divide and keep on creating more, and more, and more cells until it creates a baby! (Second Video: The Mystery of Life with Tim and Moby) - The passing traits from parents to offspring is called heredity - In the 1800’s a monk named Gregor Mendel used pea plants to find out how size ,colour, and shape (etc.) were inherited - When Gregor Mendel mixed tall plants with short plants, he noticed that the outcome was only tall plants - He called the tall height trait the dominant factor because dominated the short height trait (He called the short height trait the recessive factor) - Also by the second generation of pea plants, the recessive pea plant seemed to appear again, and after lots of research, Gregor Mendel realized that on average, every 4 pea plants would be short - In the 19th century, a british geneticist named Reginald Punnett, also experimented with peas, and created something called the Punnett square - The Punnett square helped predict the likelihood of what you would get if you crossed a tall plant and a short plant - An offspring gets one gene from each parent, either a short, or a tall gene. Each plant produced by these 2 plants will all be tall because each one one of those tall dominant genes. These new plants also produce offspring and there are different ways this could turn out but the most likely to get three tall ones and one short one - That he only figured this stuff out after carefully studying 30,000 pea plants over an 8 year period
I learned a lot of really cool things while watching these videos! ;)
These are the things that I learned from those videos: Genetics: Where do your genes come from?
-You have 2 sets of chromosomes -The Sperm and egg cell come together they make a single and make two sets of chromosomes one coming from your mother and one coming from your father. -Cells keep on dividing multiple times to finally create a baby
The Mystery of Life with Tim & Moby (Brain Pop)
- A monk from the 1800's named Gregor Mandel used pea plants to learn more about human genes.
-Mandel did lots of research and found that when short pea plants and tall plants were mixed together there were many tall plants but a short one would come up every once in a while. A British scientist named Reginald Punnett looked into this more.
- When Punnett was mixing tall pea plants and short pea plants he found that tall pea plants were much more common, this is why he named this the dominant factor because it was dominant then short plants. They had a seventy five percent to come out as a tall plant. Short plants however were much rarer then tall plants, this is why he named the genes form the short plants recessive. They had a twenty five percent chance or 1/4. The dominant factor is marked with a capital letter like "D". The recessive genes are marked with a small letter like "d". He called it the Punnett called it the punnet square
- Punnett only figured this out after studying 30,000 pea plants for eight years (Wow that must be pretty boring).
Anyway here are some things that I learned from the first video:
-We have 2 sets of chromosomes from each parent. -There are 23 of them. That chromosomes get shuffled when eggs and sperm are made. -A cell keeps dividing until you get a baby. -The mito-chondrial DNA is passed down from mother to child and the y cromosone is passed out from father to so
Things I learned from those videos: Genetics:Where do your genes come from? -You have 2 sets of 23 chromosomes -A pair of chromosomes(one from your dad and one from your mom) form a homologous chromosome. -The X and Y chromosomes determine your gender -2 X chromosomes is a female and 1 X and 1 Y chromosome make a male baby. -A random chromosome from each pair moves to a new cell.
The Mystery Of Life with Tim and Moby -Gregor Mendel predicted only 1 out of every four pea plants would be short. -Short pea plants are recessive and tall pea plants are dominant. -Every plant has 2 genes. -A geneticist named Reginald Punnett created the Punnett square. -The Punnett square is used to predict the likelihood of plants crossing or other breeding experiments.
Wow! Most of your responses are quite thorough so far. I find genetics a very interesting subject as well. Keep up the great effort. Andra - It doesn't matter which video you use in your response.
-You have 23 pairs of chromosomes, 1 set, from each parent
-A female has 2 x chromosomes, while a male has an x, and a y.
-Most adult cells, have 2 sets of chromosomes, but sperm, and egg cells have 1.
-In the 1800s, a monk named Gregor Mendel, used pea plants to find out how traits are inherited
-In the 19th century, Reginald Punnett (a british geneticist) made something called the Punnett square which also involved pea plants, and helped guess what you would get if you crossed a tall, with a short plant.
- you have 2 sets of 23 chromosomes - 1 from your father and 1 from your mother. - if we unraveled a chromosome it would stretch to 6 feet! -Reginald Punnet used pea plants to find out which was more common, tall or short pea plants? - when Punnet was mixing pea plants he found that the tall pea plants were more common than the short ones. -Reginald found this out after trying out 8,000 other pea plants. - there was a monk named Gregor Mendel who also used pea plants, but he tried to find out the different shapes, sizes, colours, and more!
Here are some things that I learned about genetics: 1.You have 2 sets of 23 chromosomes 2.A baby has half of its mother's genes and of of its father's genes 3.Because your chromosomes get shuffled, the genes that you pass on to your children are probably not the same ones that you got from your parents 4.Mito-chondrial DNA is passed down from mother to daughter (boys do not get it) 5.It only takes one dominant gene for you to have a dominant trait (and not have a recessive trait).
- A monk named Gregor Mendel used pea plants to study how things like height, colour and shape are inherited. - On average, 1 out of every 4 pea plants will be short - You have 2 sets of 23 chromosomes: One from you mother and one from your father - Mito-chondrial DNA is passed down from mother to daughter, and the Y chromosome is passed down from father to son. - A child has half of its mother’s genes and half of its father’s genes
1. We all have 2 sets of chromosomes in our bodies. 2. In total, we have 46 chromosomes. 3. Inheriting traits from your parents is called heredity. 4. Gregor Mendel experimented on pea plants to learn about heredity. 5. Reginald Punnett created something called the punnet square. 6. Moby loves peas almost as much as I do!
Here are some thing I found interesting: -You have 2 sets of 23 chromosomes, 1 set from each parent.
-You obtain one set of genes from your father and one from your father
-to form sperm or egg cells your chromosomes double when the homologous cells separate they sometimes they crossover and at random points they exchange D.N.A
- Tall pea plants are dominant
- 1 out of every four pea plant is short and the rest are tall
-Punnet only figured this out after studying 30,000 pea plants over a 8 year period and he developed the Punnet square which is a a square where the genes determine what you will look like and etc.
First Video: Genetics - Where do your Genes come from? -A human being has 2 full sets of 23 chromosomes -Most adult cells have 2 cells of 23 chromosomes Sperm and egg cells have 1 set of 23 chromosomes -Most of the Y chromosomes are handed down from father to son -Mitochondrial DNA is handed down from mother to child. -When sperm and egg cells join together they create a single cell, with two full sets of 23 chromosomes, one from your mom's side, and one from your dad's.

I learned A LOT more than five simple things :)
