Parents 1. According to Mendel's law of segregation, what is the probablity that a gamete (egg or sperm) from an Rr parent carries an R allele? 2. What is the probability that a gamete from an Rr parent carries an r allele?

1/2

Explanation:

Mendel's law of segregation states that pair of alleles representing a gene segregate during gamete formation and randomly unite during fertilization.

Hence, a gene represented by Rr alleles will segregate into R and r gametes. Out of the two gametes, one will carry R allele while the other one will carry r allele. The probability that a gamete will carry an r allele therefore is 1/2.
