yes, also dominate
No, TTT is not an example of a homozygous recessive genotype. In genetics, a homozygous recessive genotype would have two copies of the same recessive allele, such as tt. TTT would indicate a homozygous dominant genotype.
A homozygous genotype with both alleles being recessive is called a homozygous recessive genotype. This means that both copies of the gene are the same recessive allele, resulting in the expression of the recessive trait.
Tt
Homozygous recessive.
The genotype is homozygous recessive or the recessive trait is on the X chromosome and has no corresponding allele on the Y chromosome.
A cross between a homozygous recessive and an individual of unknown genotype is called a test cross.The homozygous recessive can only pass on a recessive allele to the offspring, and so any recessive in the other parent will show up in the phenotype (detectable characteristics) of some of the offspring.
In a test cross, one individual with a dominant phenotype but unknown genotype is crossed with a homozygous recessive individual. The genotype of the individual with the dominant phenotype can then be inferred based on the phenotypic ratios of the offspring.
homozygous recessive
A homozygous genotype refers to having two identical alleles for a particular gene. It can be either homozygous dominant (two dominant alleles, such as AA) or homozygous recessive (two recessive alleles, such as aa).
The frequency of the homozygous recessive genotype.
Three types of genotypes that exist for pea plant height are: TT - Homozygous dominant genotype for tall height Tt - Heterozygous genotype for tall height tt - Homozygous recessive genotype for short height
Homozygous dominant individuals have two copies of the dominant allele for a trait, homozygous recessive individuals have two copies of the recessive allele, and heterozygous individuals have one copy of each allele. Homozygous dominant and heterozygous individuals will express the dominant trait, while homozygous recessive individuals will express the recessive trait.
