which of these is a heterozygous genotype?
|
|
rr
|
|
|
Rr
|
|
|
RR
|
|
|
None of the above
|
Explanation:
Detailed explanation-1: -Individuals carrying two identical alleles (RR or rr) are known as homozygous. While individual organisms bearing different alleles (Rr) are known as heterozygous.
Detailed explanation-2: -Hybrid round peas would have one copy of the R allele and one copy of the r allele, and a genotype of Rr. An individual who carries two copies of the same allele (i.e. RR or rr) is called a homozygote (homo = same, zygote = embryo). Homozygotes produce genoctypially identical offspring when allowed to self-fertilize.
Detailed explanation-3: -An organism with one dominant allele and one recessive allele is said to have a heterozygous genotype. In our example, this genotype is written Bb.
