The process depicted in the image above is best summarized by which of the following descriptions?

During meiosis, crossing over leads to recombination of alleles between homologous chromosomes

All of the following are true statements about meiosis in mammals EXCEPT:

It produces four genetically identical gametes.

Both mitosis and meiosis begin with a parent cell that is diploid. Which of the following best describes how mitosis and meiosis result in daughter cells with different numbers of chromosomes?

Mitosis produces two identical diploid daughter cells after one round of division. Meiosis produces four haploid daughter cells after two rounds of division.

Which of the following occurs during mitosis but not during meiosis I

The chromatids of each chromosome are separated

If in the F1 and F2 generations the same characteristics appeared in both males and females, it would be safe to assume that these traits for eye color and wing length (involved the traits for fruit flies)

are autosomal characteristics

Which of the following is the most likely mode of inheritance for the disease (has a pedigree about a fam w particular GENETIC DISEASE)

autosomal recessive

The diagram above illustrates which of the following processes? (grey/white chromosomes switching 1 bottom part)

crossing-over

The genotypes of Matthew and Jane are best represented as

matthew: aa jane: Aa

A spermatocyte produces the following four sperm cells. (Four sperm cell figures. The first and second sperm cells are labeled n plus one, the third and fourth sperm cells are labeled n minus one.) These cells are the result of nondisjunction during which of the following phases?

meiosis 1

In Table I, the ratio of phenotypes in the offspring from the testcross with F1 plants that had purple flowers and inflated pods suggests that the genes for flower color and pod shape are located

on different chromosoms
