Question

Anybody pls answer the qstn ⬇

How is the equal genetic contribution of male and female parents ensured in the progeny?

Pls don't copy from the Google....!!!!​

Answer 1

Answer:

in humans, 23 pairs of chromosomes are present. out of these 22 pairs have a maternal and paternal copy.the 23rd

pair of chromosomes are called sex chromosome.each parent contribute 1 set of genes to the offspring. each cell in an organism has two copies of each chromosome one each from each parents.the germ cell of the organism has only one member of the pair of chromosome.when two gamets fuse to form progeny the pair of chromosomes is restored . thus equal genetic contribution of male and female parents is ensured in the progeny.

i hope it will help you.

pls mark it as the brainliest.

Answer 2

Answer:

Both male and female have 23 pairs of chromosomes. Both have 22 pairs of same type of chromosomes called perfect chromosomes and 1 pair of different chromosomes called hetrochromosomes or sex chromosomes.

In male XY

In female XX

In zygote formation one alle from father and one alle from mother is transferred to the baby.

This shows 50-50% contribution of male and female.
