Multiple choice help please?
1. In a chi square analysis involving genes that may be linked, which of the following statements is correct?

d)An independent assortment hypothesis is proposed because it allows you to calculate expected numbers of offspring
Explanation / Answer
Answer 1 d) An independent assortment hypothesis is proposed because it allows you to calculate expected numbers of offspring.
Answer 2 B) Meiosis only
Recombination occurs when two molecules of DNA exchange pieces of their genetic material with each other. One of the most notable examples of recombination takes place during meiosis (specifically, during prophase I), when homologous chromosomes line up in pairs and swap segments of DNA
