TT, Tt, YY, Hh, Ll, Pp, PP, MM, Nn, Rr, Qq, QQ, qq, mm, tt. Homozygous genotypes have either all dominant alleles (all capital letters) or all recessive alleles (all lowercase letters). … They are represented by one capital and one lowercase letter. Tt, Hh, Ll, Pp, Nn, Rr, Qq.
Is QQ dominant or recessive?
The gene for hair color in rabbits has two alleles Q and q. Q is dominant and codes for brown hair. q is recessive and codes for white hair.
Which genes are homozygous recessive?
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. Finally, the genotype of an organism with two recessive alleles is called homozygous recessive. In the eye color example, this genotype is written bb.
Is CC homozygous or heterozygous?
So to review some vocab, homozygous means having two of the same allele in the genotype (2 big or 2 little letters — CC or cc). Heterozygous means one of each allele in the genotype (ex: Cc).
Is DD homozygous dominant?
Suppose that the GENOTYPE (the genetic makeup for this trait) of Sam is “DD”. He is HOMOZYGOUS (has 2 identical alleles for that gene) for the dimples gene. Sally’s genotype is “dd”, so she is also considered homozygous.

Is QQ homozygous or heterozygous?
Homozygous genotypes have either all dominant alleles (all capital letters) or all recessive alleles (all lowercase letters). TT, YY, PP, MM, QQ, qq, mm, tt. 13) In this list of genotypes, which ones are examples of HETEROZYGOUS genotypes? TT, Tt, YY, Hh, Ll, Pp, PP, MM, Nn, Rr, Qq, QQ, qq, mm, tt.
What is heterozygous recessive example?
One such example is brown eyes (which is dominant) and blue eyes (which is recessive). If the alleles are heterozygous, the dominant allele would express itself over the recessive allele, resulting in brown eyes.
Is KK homozygous dominant?
“KK” is a homozygote for the dark green gene. Most autosomal dominant mutations are incomplete (as is this one) meaning that the heterzygote has a different phenotype (or appearance) than both the homozygous dominant form (KK) and the homozygous recessive for (kk).
Is EE homozygous dominant?
Homozygous dominant, means that the organism has two copies of the dominant allele, in this case EE. … Heterozygous means that the organism has one dominant and one recessive allele: Ee. Combination B is an example. Homozygous recessive means that an organism has two copies of the recessive allele: ee.
