Detailed explanation-1: -The two chromosomes in a homologous pair are very similar to one another and have the same size and shape. Most importantly, they carry the same type of genetic information: that is, they have the same genes in the same locations.
Detailed explanation-2: -The chromosomes in a homologous pair each have the same genes in the same order, but there may be variation between them, resulting in different alleles. Some of the variants in these alleles might have functional implications while others will not.
Detailed explanation-3: -Answer and Explanation: Alternative forms of a gene having the same position on a pair of homologous chromosomes is called an allele.
Detailed explanation-4: -Homologous chromosomes pair during meiosis but not during mitosis. The statement “At anaphase I, sister chromatids remain together” is false because during meiosis I, homologous chromosomes separate and move to opposite poles of the cell, rather than sister chromatids.
