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.
What else can I help you with?
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 is an allele that produce a trait in the heterozygous condition is?
homozygous
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)
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.
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.
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 the differences between homozygous dominant and homozygous recessive and heterozygous?
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.
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.
Homozygous dominant homozygous recessive?
Homozygous dominant individuals have two identical dominant alleles for a particular gene, resulting in the expression of the dominant trait. Homozygous recessive individuals have two identical recessive alleles, resulting in the expression of the recessive trait.
A trait produced from two alleles that are alike is?
A trait produced from two alleles that are alike is called homozygous. Homozygous alleles are identical forms of a gene and can be either dominant or recessive. Homozygous dominant means having two dominant alleles, while homozygous recessive means having two recessive alleles for a particular trait.
What is a gene combination for a single trait?
homozygous dominant, heterozygous, or homozygous recessive
If an organism has alleles BB?
The organism is homozygous dominant for that trait.
