Answer:
Mendel was an Austrian monk whose researches laid the foundation of genetics. The experiments conducted by Mendel led him to the foundation of two laws which are named as the law of segregation and law of independent assortment.
According to the law of segregation, the two alleles of a gene segregate during the time of gamete formation and there are 50-50% chances of each of the alleles to be received by the gametes. Hence, there are 50% chances for Y gametes to be produced and 50% chances for y gametes to be produced.
