codominance. the phenotype of the heterozygote is not intermediate between the phyenotypes of the homozygotes; rather, the heterozygote simultaneously expresses the phenotype of both homozygotes. dominance.
Which of the following is the term for when a heterozygote simultaneously expresses the phenotypes of both homozygotes?
|when the phenotype of the heterozygote differs from the phenotypes of both homozygotes||Incomplete dominance|
|In the heterozygous condition, only one allele (dominant) is expressed.||Mendelian concept|
|Heterozygote expresses both alleles/both phenotypes.||Codominance|
When the heterozygous condition expresses both homozygous conditions simultaneously it is called?
codominance. Type of allelic interaction in which the heterozygote simultaneously expresses traits of both homozygotes.
What is it called when both phenotypes are expressed?
Codominance. As opposed to partial dominance, codominance occurs when the phenotypes of both parents are simultaneously expressed in the same offspring organism.
What is phenotype example?
Examples of phenotypes include height, wing length, and hair color. Phenotypes also include observable characteristics that can be measured in the laboratory, such as levels of hormones or blood cells.
What does it mean to have multiple alleles?
Alleles are described as a variant of a gene that exists in two or more forms. Each gene is inherited in two alleles, i.e., one from each parent. Thus, this means there would also be having two different alleles for a trait. … These three or more variants for the same gene are called multiple alleles.
What is the genotype of a person is heterozygous A?
An organism with one dominant allele and one recessive allele is said to have a heterozygous genotype. In our example, this genotype is written Bb. Finally, the genotype of an organism with two recessive alleles is called homozygous recessive.
Is AA heterozygous or homozygous?
Two dominant alleles (AA) or two recessive alleles (aa) are homozygous. One dominant allele and one recessive allele (Aa) is heterozygous.
What would be the phenotypes of the offspring?
The phenotype is the trait those genes express. … Looking at the possible offspring, each box (or possible offspring) has two copies of the dominant gene. This means there is a 100% chance of the offspring having brown eyes, or being BB. It’s important to note here that each box represents a possible offspring.
Can a person’s genotype be determined by their phenotype?
No, a person’s genotype cannot be determined solely by their phenotype as many genes in our genome do not get expressed.
