HOW IS EQUAL GENETIC CONTRIBUTION OF MALE AND FEMALE PARENTS ENSURED IN THE PROGENY.
Answers
male have two chromosomes i.e. X and Y and female also have two chromosomes i.e X And X.
during formation of gametes, both the gamates get separated and they fuses with each other.
when X and Y chromosome fuses then the male child is formed and when X and X chromosome fuses then the female child is produced....

The inheritance of equal parent chromosomes ensures equal genetic contribution within the relative of male and female folk. There are 23 pairs of chromosomes. There is no pairing of all human chromosomes. 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. Females have an ideal trial of 2 X sex chromosomes and males have an inappropriate trial of 1 X and 1 Y chromosome.
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. Within the relative, the fertilized ovum receives the associated degree of equal contribution from the oldsters of genetic material. 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.
