Question

The human which has XX pair of the chromosome is called
A. Male
B. Female
C. Hybrid
D. Pure breed

Answer 1

Humans possess X and Y sex chromosomes. A human with 22 pairs of autosomes and two copies of X chromosomes as sex chromosomes are females. And a human with 22 pairs of autosomes and XY chromosomes as sex chromosomes are males. A pure breed implies to individuals that have a pair of identical alleles for a particular locus. A hybrid carries different alleles for a particular locus.

Step by step answer: Option A- Male
Most of the male mammals and a human male's genome inherits an X chromosome from his mother and a Y chromosome from his father. It has XY sex chromosomes.
Option B- Female
An adult female human is known as a woman. Normally, a woman has two X chromosomes and is capable of conceiving and giving birth from puberty until menopause. A pair of X chromosomes in females increases the secondary sexual characteristics of a female.
Option C- hybrid
The term hybrid has a broader application than the terms mongrel or crossbreed. It usually refers to animals or plants resulting from a cross between two races, breeds, strains, or varieties of the same species.
Option D- pure breed
Pure breeds are cultivated varieties or cultivars of an animal species. They are attained through the process of selective breeding. When the lineage of a purebred animal is documented, that animal is said to be pedigreed.
The correct answer is B- female.

Note: Sex chromosome is a chromosome that differs from an ordinary autosome in form, size, and behavior. The human sex chromosomes is a typical pair of mammal allosomes that determine the sex of an individual created in sexual reproduction. Humans and most other mammals possess two sex chromosomes, the X and the Y.
