Problem: Drosophila may be monosomic for chromosome 4, yet remain fertile. A recessive mutant for bent bristles is identified on chromosome 4. Determine the genotypes of the F1 and F2 progeny for the following crosses. The following cross is conductd of true-breeding adult flies: monosomic normal bristles x diploid bent bristlesSelect the two F1 genotypes that will be produced from this cross.A. _/b+B. _/bC. b/bD. b/b+E. b+/b+

🤓 Based on our data, we think this question is relevant for Professor Nehm's class at SUNY.

In a cross between a monosomic that is wild type for the trait and a diploid that is homozygous recessive, it is expected that 50% of the progeny will be monosomic, as well. In constructing a Punnet square for a cross between a diploid and a monosomic, the other supposed allele of the monosomic will just be blank.
