Frogs have 13 pairs of chromosomes. Complete this model by writing the correct number of chromosomes for each of the following:

- Sperm
- Egg
- Fertilized egg

Then, identify the type of cell division involved.

Answer :

Final answer:

Frog sperm and eggs are haploid with 13 chromosomes each. After fertilization, the frog's zygote is diploid with 26 chromosomes. These reproductive processes involve meiosis and fertilization, respectively.

Explanation:

Frogs have 13 pairs of chromosomes in their somatic (body) cells making them diploid. Hence, each somatic cell has a total of 26 chromosomes. When frogs produce gametes, such as sperm and eggs, these cells undergo a special type of cell division called meiosis to ensure that they have half the number of chromosomes as somatic cells.

This means frog sperm and eggs each have 13 chromosomes and are referred to as haploid cells. Upon fertilization, when a sperm and an egg combine, they form a zygote. This zygote is diploid, having two sets of chromosomes, one from each parent, totaling 26 chromosomes (13 pairs). Thus, the correct number of chromosomes for frog sperm is 13, for the egg is 13, and for the fertilized egg (zygote) is 26.
