Answer 2

Answer:

Among the following list of organisms, a cricket has only one type of sex chromosome called the X-chromosome.

Explanation:

Chromosomes are delicate, thread-like entities that are present in a cell's nucleus. During the process of reproduction, these chromosomes are primarily responsible for carrying and transferring genetic instructions from one generation to the next. Some species of insects, arachnids, and mammals use the XO sex-determination system (also known as the X0 sex-determination system) to decide the sex of their offspring. There is only one sex chromosome in this system, known as X. Females have two X chromosomes (XX), whereas males only have one (XO). There is typically only one X chromosome in its sperm or none at all (O).
