what does the notation rr mean to geneticists?\n○ heterozygous alleles\n○ homozygous alleles\n○ dominant alleles\n○ recessive alleles

Answer

Brief Explanations:

In genetics, when an organism has two different alleles for a gene (one dominant - represented by a capital letter and one recessive - represented by a lowercase letter like Rr), it is called heterozygous. Homozygous alleles are either two dominant (RR) or two recessive (rr). Dominant alleles are only represented by capital letters when homozygous or in a heterozygous pair, and recessive alleles are only expressed when homozygous (rr).

Answer:

heterozygous alleles
