Same genetic system as above (M recessively epistatic to P). What proportion of offspring will have white coloration from the following cross: PPmm × ppMm (uppercase P uppercase P lowercase m lowercase m crossed with lowercase p lowercase p uppercase M lowercase m)

An organism with only one complete set of chromosomes is described as:

In mice, fur color and tail length are Mendelian traits that show complete dominance and assort independently. If you focus on these two traits and cross two individuals with a resulting 1:1:1:1 offspring ratio, this suggests that the genotypes of the parents could include which of the following? Select all that apply.

Which statement explains a situation in which Mendel’s Law of Independent Assortment does NOT apply?

In wasps, females are diploid and males are haploid. In one species, 2N = 46. How many chromosomes would a male stingless bee of this species have?

Which term refers to a segment of DNA that codes for a protein?

Assume the parents of individual III-1 were both heterozygous. What is the probability that individual III-1 is homozygous dominant?

Which of the following statements are TRUE about meiosis I? Select all that apply.

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 tiny wings. When flies with the r2 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 r1 mutation with flies with the r3 mutation, and why?
