Question

which is a homologous chromosome pair?
chromatid
zygote
gamete
tetrad

Explanation:

A tetrad is formed during meiosis when a pair of homologous chromosomes (each made up of two sister chromatids) come together. A chromatid is one - half of a replicated chromosome. A zygote is a fertilized egg cell formed by the fusion of two gametes. A gamete is a sex cell (sperm or egg). Only a tetrad represents a homologous chromosome pair.

Answer:

tetrad
