Meiosis and Reproduction Review

Which of the following types of cells in humans are considered diploid?

• egg cell
• somatic
• sperm cell
• gamete

The correct number of chromosomes is maintained during fertilization in sexual reproduction by-

• meiosis, which reduces the chromosome number of the gamete by one half
• chromosomes being copied immediately after fertilization of the gametes
• mitosis, which maintains the number of chromosomes in the daughter cells
• half of the chromosomes being destroyed immediately after fertilization of the gametes.

During which phase of meiosis does crossing over occur?

• metaphase I
• telophase II
• prophase I
• prophase II

In human females, how many haploid daughter cells are produced after successful meiotic division of one cell?

• 1
• 2
• 3
• 4

A plant's diploid cells normally contain 24 chromosomes. How many chromosomes will be present in the plant's haploid cells?

• 48
• 12
• 24
• 6

During meiosis what stage will occur next?

• telophase
• anaphase I
• metaphase I
• prophase

What is NOT a location where you would expect meiosis to occur?

• human ovary
• human testes
• plant ovary
• plant leaf

What sex will a child be if the mother contributes an X chromosome?

• female, if the father contributes a Y chromosome
• Either a male or a female
• Female, no matter what
• Male, no matter what

The American buffalo has cells containing 60 chromosomes. If one germ cell of a female bison undergoes meiosis, how many chromosomes could be found in the resulting egg?
