Question

Assertion A: The Sex of the Children will be determined by

chromosome received from the father.

Reason R: A human male has one X and One Y Chromosome​

Answer 1

Both the Assertion (A) and Reason (R) are true. R is the correct explanation for A.

Explanation:

• In humans, sex determination is done by the XY type mechanism.
• Humans contain 23 pairs of chromosomes. 22 pairs of chromosomes are the same in both genders, which is called autosomes.
• The $23^{rd}$ pair is distinct in both sex and is known as the sex chromosome.
• Females have XX chromosomes and males have XY chromosomes as sex chromosomes.  
• When the X chromosome of female fuses with the X chromosome of a male, a girl child will be born
• Likewise, when the X chromosome of female fuses with the Y chromosome of a male, a boy child will be born.
• Thus, the sex chromosome of the male (father) determines the sex of the child.

Answer 2

Answer:

Both A and R are true and R is the correct explanation of A

Explanation:

There is a single mismatched sex chromosome found in human males(XY).

Those are X Or Y. The females have only X chromosome in them(XX) . Therefore thev sex is determined highly based in the chromosome inherited from the father.

When X chromosome from the mother and X chromosome from the father are inherited, the resultant offspring has XX chromosome ie. the child is (♀️) female.

When X chromosome from mother and Y chromosome from the father are inherited, the resultant offspring has XY chromosome ie. The child is (♂️) male.
