You are studying reproduction in a species of frog. imagine there was a mistake in meiosis such that all the gametes produced by two individuals are diploid rather than haploid. two of these gametes fuse. this zygote is:

This zygote is tetraploid.

Explanation:

An haploid cell contains a single set of chromosomes (one chromosome 1, one chromosome 2, one chromosome 3, etc.).

A diploid cell contains two sets of chromosomes (two chromosomes 1, two chromosomes 2, etc.).

Usually, two haploid gametes fuse and generate a diploid zygote, that has a set of chromosome from one parent and another set from the other parent.

If during meiosis the generated gametes are diploid instead of haploid, the resulting zygote from that fusion will have four copies of each chromosome. An organism that has four sets of chromosomes (four chromosomes 1, four chromosomes 2, etc.) is called tetraploid.

i believe the answer would be b. hope it : )

c is the correct answer hope this !
