XY chromosome that determine the sex in human beings are:a)Homomorphic...
Heteromorphic chromosomes determine sex in human beings.
Explanation:
Sex in human beings is determined by the presence of two sex chromosomes, X and Y. Females have two X chromosomes (XX), while males have one X and one Y chromosome (XY). The X and Y chromosomes are known as sex chromosomes because they determine the sex of an individual.
The X and Y chromosomes differ in size, shape, and genetic content, and are therefore known as heteromorphic chromosomes. The X chromosome is larger and contains more genetic material than the Y chromosome. The Y chromosome contains fewer genes, many of which are involved in male development and fertility.
In contrast, homomorphic chromosomes are chromosomes that are similar in size and genetic content. For example, humans have 22 pairs of homomorphic chromosomes, known as autosomes, which contain most of the genetic information in the human genome.
Therefore, the correct answer is option D, heteromorphic chromosomes, which refers to the X and Y chromosomes that determine the sex in human beings.
