Q

A pair of chromosomes bearin similar sets of genes, genes coding for the same trait will be at identical locations but may code for different forms of the trait, each chromosome is reffered to as a homologue

Q

A region of a chromosome that can be identified as having a role in the development of a trait, the sequence of nucleotides in a DNA molecule that codes for the synthesis of a protein of RNA, the location of a gene on a chromosome is its “locus”
