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.
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.
A recessive trait is one that is not expressed when paired with a dominant trait. It may only be visually evident when both copies of the gene carry the recessive form.
Around 20-30% of people in the US are estimated to have dimples. Dimples are considered a dominant genetic trait, so they often run in families.
Similarities in twin studies typically refer to the extent to which identical twins (who share 100% of their genes) are more similar to each other in terms of a particular trait or characteristic than fraternal twins (who share, on average, 50% of their genes). This difference in similarity between types of twins allows researchers to estimate the heritability of that trait.
If brown fur is a dominant trait in the offspring's parents, then approximately 75% of the offspring will most likely have brown fur. This is because there is a 75% chance that each offspring will inherit at least one dominant brown fur gene from the parents.
homozygous
homozygous
A homozygous trait refers to having two identical alleles for a gene (e.g., TT or tt), while a heterozygous trait means having two different alleles for a gene (e.g., Tt). An example of a homozygous trait is having blue eyes (bb), where both alleles are for blue eye color. An example of a heterozygous trait is having wavy hair (Ww), where one allele is for wavy hair and the other for straight hair.
homozygous or 2 dominant or 2 recessive.
Gg G=dominant trait g=recessive trait
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.
If the father is dominant for double eyelashes (we'll use D for the dominant allele) and the mother does not carry the trait (we'll use d for the recessive allele), all offspring will have a heterozygous genotype with one dominant allele from the father and one recessive allele from the mother (Dd). Therefore, the Punnett square would show 100% of the offspring having double eyelashes.
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...
homozygous
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.
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)
