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.
Do Parents with the dominant phenotype cannot have offspring with the recessive phenotypeous for a trait that is?
No. Parents with the dominant phenotype might be heterozygous in their genotype. This means they could carry both the dominant and recessive allele for a trait. So they could both pass the recessive allele to an offspring, who would then have the homozygous recessive genotype and recessive phenotype.
When is a recessive allel expressed in offspring?
A recessive phenotype is expressed in an offspring that has a homozygous recessive genotype for that trait.
What contains a dominant trait and a recessive trait?
Genotype
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.
What comes before a recessive allele when determining the genotype of a offspring in a punnett square?
dominant allele before a recessive trait
How many offspring are likely to have recessive traits if the parents are hybrids?
50%. There are four possible outcomes of the cross:dominant trait from "dad", dominant trait from "mom"recessive trait from "dad", dominant trait from "mom"dominant trait from "dad", recessive trait from "mom"recessive trait from "dad", recessive trait from "mom"Therefore, to get hybrid offspring (one dominant, one recessive), you have a 2 out of 4 chance.
A trait that is masked by a dominant trait is called?
DNAactually it is not DNA at all, a dominant trait, masks a recessive trait.
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.
A mother that is heterozygous for a trait and a father who is homozygous recessive for the same trait have offspring Use this information to complete the matching below Enter the letter of the item?
A. Offspring with heterozygous genotype 100 percent B. Offspring with homozygous dominant genotype 0 percent C. Offspring with at least one copy of recessive gene 50 percent
Is detached earlobes recessive or dominant?
Dominant. he has a homozygous genotype
What could be the possible genotype of those that have the PTC trait?
The PTC trait is autosomal dominant so an individual with the trait could be homozygous dominant or heterozygous.
