Question

during prophase i of meiosis, chromosomes from the mother pair up with chromosomes from the father that have the same types of genes. what are these pairs of chromosomes called, and what is the group of four chromatids they form called?
homologous chromosomes; tetrad
diploid chromosomes; quads
sister chromatids; centromeres
homogeneous chromosomes; quads

Explanation:

In meiosis Prophase I, chromosomes from mother and father with same genes pair as homologous chromosomes. Each homologous chromosome has two chromatids, so a pair (two chromosomes) forms a tetrad (four chromatids). Other options: Diploid refers to cell ploidy, sister chromatids are identical in a chromosome, "homogeneous chromosomes" is incorrect term. So the correct pair is homologous chromosomes and tetrad.

Answer:

A. Homologous chromosomes; tetrad
