NEET BIOLOGY

Detailed explanation-1: -Homologous chromosomes are the chromosomes which contain alleles for the same type of genes (one from sperm and one from egg) or can be called similar. Homologous chromosomes are similiar but not identical. Each carries the same genes in the same order, but the alleles for each trait may not be the same.

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 humans, the twenty-third pair is the sex chromosomes, while the first 22 pairs are called autosomes. Typically, biologically female individuals have two X chromosomes (XX) while those who are biologically male have one X and one Y chromosome (XY).

Detailed explanation-4: -The first 22 pairs of chromosomes are known as autosomes. These are homologous chromosomes, which means that their chromosomal sides have the same genes (DNA sections) in a similar sequence.

Detailed explanation-5: -In biology, homologous chromosomes are paired chromosomes. They essentially have the same gene sequence, loci (gene position), centromere location, and chromosomal length.
