Is HH homozygous or heterozygous?

Is heterozygous hh or HH?

Dominant alleles are written as a capital letter (H), and recessive alleles as a small (lower case) version (h) of the same letter. whereas one with two different forms (Hh) is called heterozygous (a heterozygote) – also called a hybrid.

Is HH a homozygous?

A full head of hair is a dominant feature, with the homozygous gene of HH. However, the recessive trait – baldness – can be manifested in an individual with the homozygous recessive gene, or hh.

Is HH heterozygous dominant?

For both heterozygous individuals (Hh), the gametes can carry the H (dominant allele) or the h (recessive allele). … For HH, the gametes can only carry H (the dominant allele).

Which is a heterozygous genotype HH?

The heterozygous genotype for one’s hair is Hh. … If the genotype is Hh (H stands for dominant brown while h stands for recessive blonde), then the individual would have blonde hair.

Which is a homozygous dominant hh or HH?

Individuals with dominant phenotypes can be either homozygous (HH) or heterozygous (Hh). When a recessive (hh) is selected against, a reservoir of recessive alleles remains in the heterozygotes (Hh) of the dominant phenotype.

What is an example of homozygous?

Homozygous means that the organism has two copies of the same allele for a gene. … For example, pea plants can have red flowers and either be homozygous dominant (red-red), or heterozygous (red-white). If they have white flowers, then they are homozygous recessive (white-white). Carriers are always heterozygous.

Is the pedigree for Huntington’s disease a dominant or a recessive disease trait?

This condition is inherited in an autosomal dominant pattern , which means one copy of the altered gene in each cell is sufficient to cause the disorder.

What is the phenotype of a person whose genotype is hh?

Bombay phenotype occurs in individuals who have inherited two recessive alleles of the H gene (i.e.: their genotype is hh).
