Question

Explain how equal genetic contribution of male and female parents is ensured in the progeny

Answer 1

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

During the formation of gametes as a result of reductional division (meiosis), sperms - XY & eggs - XX receive only single genome of a parent.

When fertilization occurs, one genome each from sperm & egg reaches the zygote.

It means both male & female parents contribute exactly equal amount of genetic material to the offspring.

_____________________________

$\leadsto$ The inheritance of equal parent chromosomes ensures equal genetic contribution within the relative of male and female folk.

$\leadsto$ There are 23 pairs of chromosomes.

$\leadsto$ There is no pairing of all human chromosomes.

$\leadsto$ The primary twenty-two trials are called autosomes out of those twenty-three pairs, and the remaining one pair is also thought to be sex chromosomes drawn as X and Y.

$\leadsto$ Females have an ideal trial of 2 X sex chromosomes and males have an inappropriate trial of 1 X and 1 Y chromosome.

$\leadsto$During the replication process, the male germ cell (haploid) fuses with the feminine gamete (haploid) resulting in the formation of the diploid fertilized ovum as the fertilization method takes place.

$\leadsto$ Within the relative, the fertilized ovum receives the associated degree of equal contribution from the oldsters of genetic material

$\leadsto$ The comparatively twenty-three pairs of chromosomes, the parent contributes twenty-two autosomes and one X or sex chromosome, whereas the feminine parent contributes twenty two autosomes and one chromosome.
