What is TT Tt tt?
These are letters assigned to alleles or variations in genes. TT means that there are two dominate alleles. Tt means that there is one dominate and one recessive and tt means that both are recessive.
What genotype is homozygous?
Total dominant genes or total recessive genes. Therefore, either TT or tt, not Tt.
What is Having two unlike genes for the same trait?
When two alleles differ from each other, such as Tt, it is called heterozygous, hetero meaning different. When alleles are the same (TT) it is called homozygous, homo meaning same.
What two alleles could produce a trait controlled by a dominant allele?
Tt or TT
How many alleles does a pea plant gamete have for the height gene?
TT or Tt
What are the letters for homozygous dominant heterozygous and homozygous recessive?
homozygous dominant means two alleles that are the same that are capital letters, heterozygous recessive means that to alleles are different BUT the same letters in lower case. (alleles for gender) EX: TT, Tt is homozygous dominant tt, tt is heterozgous recessive
If the male parent cell is heterozygous for a traitTt what alleles could the sperm cells possibly have?
If a man has the genotype Tt, then he is heterozygous. Homozygous would be TT or tt. If a man has Tt, then he can either donate a T or a t to the sperm, but not both.
Which two combinations of allels could produce a trait controlled by a dominant allele?
with TT or Tt
Genetics Tt and TT are examples of?
They are examples of a pair of alleles, possibly from the vitamin D receptor gene
A plant with the genotype TT is called?
Genotype TT is called a homozygous genotype. The TT indicates identical alleles, and the capital letters represent their dominant trait.
What are organisms that have two different alleles?
When you have two identical alleles you are said to be homozygous for that particular trait. If the trait is dominant, then you are homozygous dominant. If the trait is recessive, then you are homozygous recessive.
What is the probability of a homozygous recessive offspring?
It depends. If it's a heterozygous cross, (Tt x Tt), there's a 25% chance. If it's a homozygous dominant cross (TT x TT), the chance is 0%. Neither parent has the alleles for a recessive trait, so none of their offspring can have the recessive trait. If it's a homozygous recessive cross (tt x tt), there's a 100% chance. The only alleles the parents can pass on are recessive.
