You make a monohybrid cross in a diploid organism involving a gene that shows incomplete dominance. How many phenotypic classes are expected among the offspring?

What is the probability that individual IV-1 will be affected?

A mouse geneticist considers five homozygous recessive mutant strains of mice (1–5). All show pink eyes. Crosses were made using all possible pairs. WT indicates wild type eye color and M indicates mutant pink eyes. Complementation test table Mouse population Mouse 1 Mouse 2 Mouse 3 Mouse 4 Mouse 5 Mouse 1 M WT M M WT Mouse 2 M WT WT M Mouse 3 M M WT Mouse 4 M WT Mouse 5 M Based on these results, how many different genes were mutated in making these five lines?

In wasps, females are diploid and males are haploid. In one species, 2N = 22. How many chromosomes would a male stingless bee of this species have?

A scientist studying Drosophila received three different mutants that all had tiny wings. When flies with the r1 mutation were crossed with flies with the r2 mutation, all offspring had wild-type wing size. When flies with the r1 mutation were crossed with flies with the r3 mutation, all offspring had wild-type wing size. What wing size would you expect if the scientist crossed flies with the r2 mutation with flies with the r3 mutation, and why?
