Imagine a disease that kills 50% of the male roaches i a population. do you think this would affect birth rate? briefly explain.
dmitriy555 [2]
Well either way, it would be difficult for them to find mates, but if 50% of males were gone, the females would be able to reproduce with the men they have but if the females were killed off, it would affect birth rates even worse because the women carry the offspring. All of this also includes the offspring's gender

Dad: TtBb

Mom: ttbb

You have to use distribution for dihybrid crosses.  Meaning, the first allele of each trait has a equal chance of being paired with the other allele of the other trait.  So for example with Dad, I will number the traits:

T(1)t(2)B(3)b(4)

To set up the possibilities from Dad, it would be 13, 14, 23, 24: TB, Tb, tB, tb.  Same idea goes for Mom, except since all alleles are the same, you only need to make one column for Mom, since if you did all 4, the other 3 would just be repeats of the 1.

Cross:

                 tb

TB           TtBb

Tb           Ttbb

tB            ttBb

tb            ttbb

The phenotypic ratio is 1 Tall Brown: 1 Tall Blue: 1 Short Brown: 1 Short Blue
