Which of the following best describes the process that diagram 2 represents?
cell division that occurs in reproductive structures of an organism
cell division that occurs in the repair process of damaged skin cells
occurs in all cells of the body system
process prior to the first stage of cell division
The greatest amount of genetic variation occurs in offspring that reproduce —
sexually through fission
sexually through meiosis
asexually through mitosis
asexually through budding
The steps of crossing over during meiosis are shown in the diagram. What is the significance of crossing over in Meiosis I?
Crossing over ensures that the four daughter cells produced at the end of Meiosis II have the original number of chromosomes in each cell.
Crossing over ensures that the two daughter cells produced at the end of Meiosis I have half the original number of chromosomes in each cell.
Crossing over ensures that the same combination of alleles remains in each of the four daughter cells at the end of Meiosis II.
Crossing over ensures that the chromosomes in the four daughter cells produced at the end of Meiosis II will have a different assortment of genes than the corresponding chromosomes in the original cell.
There are a total of _______ chromosomes in human sperm or egg cells.

32
16

A diploid cell has 12 chromosomes. How many chromosomes does the haploid cell of that organism have?
6
12
24
The diagram shows a cellular process that occurs in organisms. What is this process called?
Meiosis
Mitosis
Cloning
Budding
Gametes must be haploid because-
gametes are small and can hold only the haploid number of chromosomes
the gametes chromosomes will be replicated prior to cell division
two gametes will unite during fertilization to create a diploid cell
fertilization results with a haploid zygote
Homologous chromosomes are (2 answers)
Same in size, shape, and genetic content
Identical to each other
One is given from the mother and one from the father
They are unrelated to each other
What phase is this?
Prophase 1
Metaphase 1
Anaphase 1
Telophase 1
Crossing over helps to increase
male spermogenesis
genetic variation
DNA replication
female Oogenesis
Which stage of Meiosis is shown in this drawing?
Metaphase I
Anaphase I
Metaphase II
Anaphase II
The chromosomes that pair up during Prophase I of meiosis, are called __________ chromosomes.
homozygous
deuterostomal
homologous
fertilial
