NEET BIOLOGY

Detailed explanation-1: -Homologous chromosomes are made up of chromosome pairs of approximately the same length, centromere position, and staining pattern, for genes with the same corresponding loci. One homologous chromosome is inherited from the organism’s mother; the other is inherited from the organism’s father.

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.

Detailed explanation-3: -In biology, homologous chromosomes are paired chromosomes. They essentially have the same gene sequence, loci (gene position), centromere location, and chromosomal length.

Detailed explanation-4: -The 46 chromosomes of a human cell are organized into 23 pairs, and the two members of each pair are said to be homologues of one another (with the slight exception of the X and Y chromosomes; see below). Human sperm and eggs, which have only one homologous chromosome from each pair, are said to be haploid (1n).
