Q5) Humans have two different sex chromosomes, X and Y. Based on Mendel’s laws, a male offspring will inherit which combination of chromosomes?
Key points: In humans and other mammals, biological sex is determined by a pair of sex chromosomes: XY in males and XX in females. Genes on the X chromosome are said to be X-linked. X-linked genes have distinctive inheritance patterns because they are present in different numbers in females (XX) and males (XY).
