Homologous chromosomes pair up and crossing over occurs during....

Prophase I

Prophase II

Metaphase I

Metaphase II

Answer explanation

To cross over there has to be homologous chromosomes to swap information. Crossing over therefore has to happen during prophase I, as by prophase II the homologous chromosomes have been separated into two new daughter cells.

A giraffe has a diploid (2n) chromosome count of 62. How many chromosomes will it have in each cell after each type of cell division?

Mitosis: 62

Meiosis: 31

Mitosis: 62

Meiosis 124

Mitosis: 31

Meiosis: 62

Mitosis: 62

Meiosis: 62

Answer explanation

Mitosis results in diploid cells that are identical to each other and have the same number of chromosomes. Meiosis results in haploid cells that have HALF the original number of chromosomes. So, if the parent cell has 62 chromosomes, after mitosis there will be 62 chromosomes, but after meiosis there will be 31.

The matching pair of chromosomes shown in the diagram, one inherited from mom and one inherited from dad are called......

sister chromatids

centromeres

autosomes

Answer explanation

Homo = similar or the same. They are homologous because they have the same genes, just possibly different variations of those genes (blue eyes/brown eyes, straight hair/curly hair).
