Homozygousity is defined as having the two alleles that are the same for a certain locus. For example, AA or AA are both homozygous. Dominance, however, is a different concept and it is independent of homozygousity. In addition, both dominance and homozygousity are independent of the sex of the individual (unless the trait is X-linked) Therefore, the three possibilities of homozygous dominant, heterozygous, and homozygous recessive for a trait are available for a male just as a female individual.

A living thing that shows a dominant trait may be homozygous dominant or homozygous recessive for the trait true or false?
False because a living thing that shows a dominant trait can not be homozygous recessive. If it is homozygous recessive it will show recessive trait. A living thing that shows dominant trait may be homozygous dominant or hetrozygous.
What does it mean to be homozygous dominant heterozygous or homozygous recessive?
Homozygous means "same" so a homozygous recessive trait would be a same [with parents] trait that is not the stronger trait which is dominant. Dominant is stronger showing trait, recessive is weaker trait. If you are dealing with Punnett squares then tt is homozygous recessive and TT is homozygous dominant. Hope this helped...
What is an allele that produce a trait in the heterozygous condition is?
homozygous
What is the genotype of a child if the mother is homozygous for the dominant trait and the father is homozygous for the recessive trait?
The dominant parent is most likely homozygous dominant, and the recessive parent has only the homozygous genotype. So the dominant parent can pass on only dominant alleles for this trait, and the recessive parent can pass on only recessive alleles for this trait. So all of the offspring would be heterozygous and have the dominant phenotype.
What does it mean that an organism is homozygous dominant for a trait?
Homozygous Dominant for a trait means that an organism has two dominant alleles for that trait. Here's an example: Trait: Widow's Peak Widow's Peak allele: Dominant (D) No widow's peak allele: Reccessive(d) Homozygous Dominant (DD) Homozygous Reccessive (dd) Heterozygous (Dd)
Father with homozygous genes for dominant trait?
This means that the father has two copies of the dominant allele for a particular trait. As a result, all of his offspring will inherit at least one copy of the dominant allele from him. This implies that all his offspring will either express the dominant trait or be carriers of the dominant allele.
A parent that is homozygous for a dominant trait is crossed with a parent that is homozygous for the recessive trait What percentage of the offspring will display the dominant trait?
100% of the offspring will display the dominant trait because the homozygous dominant parent can only pass on the dominant allele. The offspring will inherit one dominant allele from the dominant parent and one recessive allele from the recessive parent, resulting in a heterozygous genotype expressing the dominant trait.
What is a gene combination for a single trait?
homozygous dominant, heterozygous, or homozygous recessive
A genotype consisting of two identical alleles of a gene for a particle trait?
it is a homozygous or heterozygous ( RR or rr)
Is detached earlobes recessive or dominant?
Dominant. he has a homozygous genotype
A dominant phenotype will only be expressed if the individual is homozygous dominant for that trait?
Well actually not necessarily. An individual can be homozygous or heterozygous dominant for a trait. As long as they have that dominant allele in that specific genetic trait, they will automatically express the dominant phenotype. If a person is homozygous dominant, it just means that they will pass on both dominant traits to the offspring. If a person is heterozygous dominant , it means that they will pass on both a dominant and recessive trait to their offspring.Hope that helps ! =D
In which offspring does a dominant trait appear?
if a trait is recessive, it can only be expressed if its other trait is recessive as well. If the other trait in the genotype is dominant, it will block the recessive factor. But if both are recessive, they will be able to be seen in the offspring.
