Recessive alleles require the individual to inherit two copies in order to be expressed. Recessive alleles are masked by dominant alleles. A person's genotype is the combination of the alleles they have. If a person inherits two dominant alleles, they are said to be homozygous dominant. If a...
BB represents the dominant homozygous genotype with two dominant alleles in the progeny with the phenotype of black hairs whereas bb represents the recessive alleles homozygous for the recessive trait or recessive phenotype of brown hairs. Two offspring will be heterozygous, Bb genotype and a ...
Definition Homozygous, meaning similar, is a specific genotype which exists when a child has either two recessive or two dominant genes from the parents.DefinitionHomozygous, meaning similar, is a specific genotype which exists when a child has either two recessive or two dominant genes from the ...
It is a heterozygous genotype for a particular gene if there are two different versions of it. For instance, a heterozygous for eye colour corresponds to say that you have one allele for black and one for brown.
1 ratio of the genotype. About one-fourth will be homozygous dominant for round seed shape (RR), half will be heterozygous for round seed shape (Rr), and one-fourth will have the homozygous recessive wrinkled seed shape (rr). The phenotypic ratio in this cross is 3:1. About three-...

An organism with a heterozygous genotype is sometimes called a heterozygote for that genotype. This is true for homozygous genotypes, sometimes called homozygotes. Dominant and Recessive Inheritance For this type of inheritance, it is helpful to look at alleles using letters where a capital letter ...
