For instance, one homozygous genotype for pea plant height is TT, which means it will have the phenotype “tall.” Genotype can also be homozygous for recessive genes as well.
Is homozygous a phenotype?
A homozygous phenotype is the product of two identical genes.
Is homozygous and heterozygous a phenotype?
Consequently, a test cross can help determine whether a dominant phenotype is homozygous or heterozygous for a specific allele. … Recessive alleles only express their phenotype if an organism carries two identical copies of the recessive allele, meaning it is homozygous for the recessive allele.
Is being heterozygous a phenotype?
The terms heterozygous and homozygous can only describe one genotype, or phenotype. Sometimes an organism will be described as a “heterozygous individual” but this term only applies to the one genotype that is being discussed.
What are examples of phenotype?
Examples of phenotypes include height, wing length, and hair color. Phenotypes also include observable characteristics that can be measured in the laboratory, such as levels of hormones or blood cells.
What are the 3 types of genotypes?
There are three types of genotypes: homozygous dominant, homozygous recessive, and hetrozygous.
Is AA homozygous or heterozygous?
Two dominant alleles (AA) or two recessive alleles (aa) are homozygous. One dominant allele and one recessive allele (Aa) is heterozygous.
Is LL homozygous or heterozygous?
Red hair is a recessive trait. A person who is heterozygous for red hair has one allele for a dominant trait, like brown hair, and one allele for red hair. They can pass the red hair allele to their future children. If the child inherits the same allele from the other parent, they’ll be homozygous and have red hair.
What is heterozygous a blood type?
Heterozygous means one dominant & one recessive allele. Since they are Type “B“, the dominant allele is IB, & the only recessive allele for blood type is “i”.
