A (Only zygotes with balanced genomes will survive to adulthood. What proportion of F1 zygotes have a balanced genome? B. Draw the genotype(s) and state the phenotype(s) of the surviving progeny you mentioned in part A above. For each different genotype/phenotype indicate it's frequency among the surviving progeny.

Question
The genotype of a Drosophila with a heterozygous translocation
between chromosome 2 and chromosome 3 is shown below, where bw =
brown eyes and e = ebony body:
bw+
bw
e
Assume there is no crossing over in the female and that alternate =
adjacent 1 = adjacent 2 disjunction. [Yes, these assumptions are incorrect, but
they make the problem much easier!] Two individuals of the above genotype,
i.e. both heterozygous for this 2;3 translocation and both heterozygous for bw
(on chromosome 2) and e (on chromosome 3) are crossed.
A (Only zygotes with balanced genomes will survive to adulthood.
What proportion of F1 zygotes have a balanced genome?
B. Draw the genotype(s) and state the phenotype(s) of the surviving
progeny you mentioned in part A above. For each different genotype/phenotype
indicate it's frequency among the surviving progeny.
