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.
The <em>TYR </em>gene is responsible for the production of the enzyme tyrosinase which is crucial in the production of melanin which is primarily responsible for skin pigmentation and for pigmentation of other organs. In albinism, there is mutation of the <em>TYR </em>gene therefore there will be no transcription of DNA to mRNA and no translation of mRNA to the enzyme tyrosinase leading to its deficiency. The deficiency of tyrosinase will eventually lead to the absence of melanin and ultimately, the absence of pigmentation in an organism.
