If you look at the F2 phenotypic classes, you will see that they tend to be paired: +++ and wmb each have similar numbers, w++ and +mb are similar, ++b and wb+ are similar, and +m+ and w+b are similar. Explain why there are always paired classes in a testcross like this, using the processes of crossing over and meiosis to explain your reasoning.
Homework Answers
Answer:
The three genes are linked on a same chromosomes as +++/wmb. Gametes will be formed by meiosis. During meiosis, crossing over takes place by which the genotype produces 8 types of gamtes.
When single crossover happened between w & m, it produces two types of gametes almost in equal proportions as +mb & w++. So these two gametes are similar.
When single crossover happened between m & b, it produces two types of gametes almost in equal proportions as ++b & wm+. So these two gametes are similar.
When double crossover happened between w&m and m&b at a time, it produces two types of gametes in almost similar as +m+ & w+b. So these two gametes are similar.
If crossover doesn't happened, it produces two types of parental combination of gametes almost in equal numbers as +++ & wmb.
Like that 8 type of gametes are produced by meiosis.

True A ® True False 2 Points: 1 Mistakes happen when cells divide and make copy of genetic information. These mistakes cause mutations in somatic cells and can cause cancer. However, cells with mistakes don't always cause cancer. Why? A Because the cigarette smoke does not always cause mutations. Some smokers can remain cancer-free thanks to their strong immune systems.

If you wanted to lift something heavy using this device, would
you have the heavy object connected to the larger disc and then
pull one the smaller disc, or vice-versa? Why? What would be the
effect of using this device on the speed that the object lifts?
That is, if you pulled your string at a speed of 10 cm/s, would the
object lift 10 cm/s, or would it lift faster or slower?
