Chapter 2, Problem 21P
Summary Introduction
To determine: The progeny obtained from the cross between male and female of A/A.
Introduction: The descendants of a person, animal, or plant; offspring are known to as progeny. Progeny is a subsidiary of Ambry Genetics that provides the family history, pedigree, and genetic data administration software to clinicians, researchers, and laboratories worldwide.

But for part A if you cross dd ll x DD LL, won't all the offspring be DdLl (dark colored and long legged), so wouldn't NONE of the offpspring have short legs and light body coloration? Isn't the 9:3:3:1 ratio only for two heterozygous dihybrid crosses? Where is the 25/4 coming from? Could you draw a punnett square to demonstrate.
In a cross of EeFfGgHh and EEFfGGhh individuals, what is the probability that an EEffGGhh individual can be produced?
In the cross between a female AaBbccDdee and male AabbCcDdee, what
proportion of the progeny are expected to be phenotypically identical to the female parent?

- In the following cross, imagine that you have a female fly that has two Xs and one Y due to a nondisjunction event in her mother's germ cells. Draw out what the possible gametes are for both the female and the male and also a Punnett square showing the genotypes, phenotypes, and sex of the possible flies as a result of this cross. You do not need to provide the probabilities of each of these.
