Genetic Variety in Reebops







When making the lady bugs in this project, genetic variety is very important. First of all, without genetic variety everything looks the same. For example, in the reebops, if the first generation or the parent bug was a red eyes which was recessive, and the bug breeded with a black eyed dominent bug, the black eyes will be dominent. Then if the other bug which the origional parent bug breeded with was hetrozygous, the children of the bugs have a 25%chance of being red eyed. I had an ugly bug born in my fourth generation The bug had no wings, yellow mutation and no dots with short legs. This did not look very good compared to the previous bugs of mine. Sooo, if you think you are ugly, blame your parents for having you the way you are.



Genetic diseases are heredity. So, for example, if both the parents of a bug had familial Dysautonomia, the bug will probably get the disease depending wether if the parent is homozygous or hetrozygous.



If you think you are special, and maybe you are, without genetic variety, every one would be special with your talent. You will not be very special then.



During the mating, we sometimes had the same color for our chromosomes, so we had to use some type of symbol to repersent our own chromosome. Therefore, we are a little different. Without variety, we are all the same. These are pictures of bugs that look alike but are tottaly different to prove my point.(top)

This week in science;

on Monday, we talked about incomplete dominence, or which the child is a mix of both the parents.


(Exp.---white flower*Red flower=Pink flower.


This is a really cool site that told me a lot about incomplete dominence:::

The next day, i got a migrane and had to miss the first 4 periods of school, so this is what i learnt from that day:when you have 2 dominance for a trait, it becomes a co-dominant. This happens in blood when there is two DOMINANT blood types mixed like A and B (AB).Then on top of that, there is the proteins that attach on to the blood types.(positive and negative.) The positive always is the dominant one.
I don't know what happened the rest of hte week in science.

This week in science, we did many things, First on Monday, we had a snow day, on tuesday, we learnt on how the Class' results did almost support the whole school's results.
On Wednesday, we went over some of the things about Genetics. Then Finley told us some things about the Lab that we will be doing th enext day. We created "egg and sperm cells for the experiment."
On thursday, we learnt that the Genetic Mutation always results in the strand mutated becoming the Dominant Gene.
On Friday, we did the experimen of mixing uop sperm and egg cells and looking at what the outcomes would look like. Then we had a quiz that we had to do at home whch I just hot to see.
This is what tje quiz was

Spiderman and Spidergirl got married and soon found out that
Spidergirl was expecting a son. Spiderman couldn't wait to
welcome his new son into the world and was looking forward
to fighting crime with him. However, when he was born
Spiderman realized that his son does not have his parents'
"spider" quality. Spiderman believes that the baby might
actually be Batman's! (Remember, Batman has ZERO special powers)

What do you know about the "spider" trait?

What could spiderman and spidergirl's genotypes be?

Did spidergirl have batman's baby? Support your answer with an explanation

Hard Quiz.

Science

This week in science, we learnt how to make a punnet square and what a Homozygous or a Hetrozygues is.
A homozygues is a species that has the same trate from the mom's side and the Dad's side.
A hetrozggues is a species that has two different trates. One from the Dad's side and one on the mom's side.
The recessive trait is always the trait that does not take over unless there are two rrecessive traits, which makes it a homozygues.
If hter is a dominent gene and a recessive gene, the dominent gene always takes over.
This is a great video that i found that helped me understand Genetics.
