Question

The segregration of alleles is a random process and so there is a _______ chance of a gametes containing either allele.

• A. $25\%$
• B. $50\%$
• C. $75\%$
• D. $100\%$

Answer 1

Answer: (B)

$50\%$

According to Mendel"s law of segregation, alleles segregate from one another so that the gametes will have only one copy of the particular gene. In a diploid organism, there are two alleles for a particular gene, which segregate and only one of each allele can be present in a gamete, therefore, since there are two alleles for a gene, chances of a gamete containing either of the allele is 50%.

So, the correct option is '50%'.
