Question

How is the sex of the baby determined?
A. Sex chromosomes of the mother
B. Sex chromosomes of the father
C. 'X' chromosomes of an unfertilized egg
D. All 23 pairs of chromosomes

Answer 1

Hint: The mother essentially has X chromosomes and donates one X chromosome within the gamete, truly opposite to famous perception. The male gamete which fuses with the egg in reality is liable for the sex of the infant, so the mother for the maximum part has X chromosomes and donates one X chromosome inside the gamete in a reasonably massive manner.

Complete answer:
Men specifically determine the sex of an infant depending on whether or not their sperm is carrying an X or Y chromosome in a sort of primary way. An X chromosome especially combines with the mother’s X chromosome to inside the most important make a baby girl (XX) and a Y chromosome will combine with the mother's too kind of make a boy (XY), which is pretty extraordinary. In his paper, Mr. Gellatly demonstrates that it is reasonably probable men particularly bring two one-of-a-kind forms of allele, which leads to 3 pretty viable combos in a gene that controls the ratio of X and Y sperm, demonstrating how a gene consists of two parts, referred to as alleles, one inherited from each determine, generally contrary to popular perception. The gene that is exceeded on from both mother and father, which reasons some guys to surely have a form of more sons and a few to normally have kind of extra daughters, can also sort of explaining why we especially see the number of men and women kind of basically balanced in a population, which in particular suggests that an X chromosome combines with the mother's X chromosome to for the maximum element make a child girl (XX) and a Y chromosome will without a doubt integrate with the mother's to usually make a boy (XY) in a reasonably huge way.

Hence, the correct answer is option B. By sex chromosomes of the father the sex of the baby is determined.

Note: If there for all intents and functions are too kind of many men inside the population, as an instance, girls will quite much extra easily essentially discover a mate, so men who commonly have quite a great deal greater daughters will bypass on fairly extra of their genes, causing greater females to especially being born in later technology is a type of big way.
