Two alleles that are the same; represented by two letters of the same case ( HH, hh)
A) gene
B) heterozygous
C) homozygous
D) allele

Correct answer is C.

Explanation: One of my favorite subjects. When it comes to alleles, if a letter is the same twice it is refered to as Homozygous. The opposite would be hetero. This is because the alleles are a hybrid or are not concrete such as something as hair color maybe represented as RR. RR is homozygous (this is just an example) Rr would be heterozygous. The capital "R" represents the dominant trait while the lowercase "r" represents recessive. In this case The capitial letter is most likely going to be represented. Good Luck!!!
