hram777 [196]

Answer:

<em>The probability of forming a "Y" gamete is 50%. The probability of forming a "y" gamete is 50%.</em>

Explanation:

Mendel was an Austrian monk whose findings led to make the foundation of genetics. Hence, Mendel is known as the father of genetics. He formulated two laws based on the researches he made:

  • Law of segregation
  • Law of independent assortment

According to the law of segregation, alleles segregate independently at the time of gamete formation. There is an equal chance for a gamete to carry the dominant or the recessive allele.

Hence, the probability of a gamete carrying a 'Y' or a 'y" allele will be 50% each.
