Question

The two versions of a trait (character) which are brought in by the male and female gametes are situated on

पर्याय

• copies of the same chromosome

• two different chromosomes

• sex chromosomes

• any chromosome

Answer 1

copies of the same chromosome

Explanation -

An organism inherits two copies of each chromosome, one each from the male and female parents. The two forms of a gene controlling a character (two versions of a trait) are present at the same location on the two copies of one of the chromosomes. At the time of gamete formation, when a chromosome pair segregate and move to different gametes, two forms of a gene also segregate, each gamete receiving one copy of a chromosome along with one form of a gene. When these gametes from two parents fuse, the two copies of the same chromosome along with the two forms of a gene are also brought together in the organism of the next generation.
