Tt
What else can I help you with?
Is TTT an example of a homozygous recessive genotype?
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.
What letters are used to represent a homozygous?
Two of the same letter. For example, if you have a homozygous organism for dominant red color, then the letters to represent their genotype would be RR. However, if the red color is a recessive trait, then a homozygous organism with that trait will have the genotype rr.
A homozygous genotype where both alleles are recessive are called?
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.
What is the genotype for homozygous recessive?
yes, also dominate
What word describes the genotype bb?
Homozygous recessive.
What genotype must the person have who possessed the recessive phenotypes?
The genotype is homozygous recessive or the recessive trait is on the X chromosome and has no corresponding allele on the Y chromosome.
What is the name for a cross between an individual of unknown genotype and a homozygous recessive?
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.
Which genotype is used in a test cross?
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.
What has the Tt genotype?
The allele pair Tt is used to represent an individual who has a dominant heterozygous genotype for tallness. The dominant gene but not the recessive gene is physically manifested.
Is the trait TT heterozygous or homozygous?
Yes.A homozygous genotype is a gene with two identical alleles. Recessive genes are represented by a lowercase letter. Thus, a homozygous recessive genotype would be two identical genes with lowercase letters.
In a testcross an organism with a dominant phenotype but unknown genotype is crossed with what to establish its genotype?
homozygous recessive
What genotype is homozygous?
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).
