Question

question 6
how many different alleles of a gene like beta - globin can an individual have?
(a) several hundred, since there are hundreds of known brca1 alleles
(b) four: two from their father and two from their mother
(c) only two: one from their father and one from their mother
(d) one for males and hundreds for females
(e) one for males and two for females

Explanation:

Humans are diploid organisms. For a particular gene locus, an individual inherits one allele from the father and one from the mother, so they have two alleles for a gene like beta - globin.

Answer:

C. Only two: one from their father and one from their mother
