The genes for A, B, C and E assort independently. If a plant with the genotype AaBBCcEe is crossed with a plant with the genotype aaBbccEe, what is the probability of progeny having the genotype aaBbCcee?

Solutions

Expert Solution

AaBBCcEe * aaBbccEe

let`s divide this cross into four different crosses

1) Aa * aa

A a
a Aa aa
a Aa aa

probability of getting aa= number of aa/total number=2/4=1/2

2) BB * Bb

B b
B BB Bb
B BB Bb

probability of getting Bb= number of Bb/total number=2/4=1/2

3) Cc * cc

C c
c Cc cc
c Cc cc

probability of getting Cc= number of Cc/total number=2/4=1/2

4) Ee * Ee

E e
E EE Ee
e Ee ee

probability of getting ee= number of ee /total number=1/4

probability of getting aaBbCcee= probability of getting aaprobability of getting Bbprobability of getting Cc probability of getting ee=1/21/21/21/4=1/32
