What type of allele is always expressed regardless of whether the individual is homozygous or heterozygous for it? A. Both the dominant and recessive alleles B. Recessive allele C. Allosteric allele D. Lethal allele E. Dominant allele Define co-dominant and multiple alleles and explain how th...
What is an allele? What are the differences between dominant and recessive alleles? What are some examples of each allele as well? What is a recessive trait? 1) A trait that not everyone in your family share. 2) A trait only visible when organisms are heterozygous for the responsible gene...
Heterozygous allele is that which has both dominant and recessive genes. Ex: Tt.
same allele is homozygous. An individual who carries two different alleles for a certain gene is heterozygous. So here are some possibilities of eye colour below: A person with two blue alleles will have blue eyes. A person with two brown alleles will have brown eyes. ...
When a person has a heterozygous genotype, with one normal and one mutated copy ofHEXAthey do not have the Tay-Sachs phenotype, but are actually incompletely dominant at the protein level. These people have lessHEXAthan unaffected individuals, but the amount produced is enough to evade the phen...
with a heterozygous mate, though with a homozygous dominant parent, once again “GG,” the offspring would again be heterozygous. A monohybrid cross is often the easiest way to begin learning basic genetics, since it only compares a single trait, unlike a dihybrid cross that considers two ...
What are dominant alleles and recessive alleles? A dominant allele will lead to expression of the dominant trait in both homozygous dominant and heterozygous individuals. A recessive allele will only lead to expression of a recessive trait in homozygous recessive individuals.What...
A homozygote is an organism that has inherited the same allele twice, once from each parent. The main signs that an organism is...
What is an Amorphic allele? A genetic null or amorphic allelehas the same phenotype when homozygous as when heterozygous with a deficiency that disrupts the locus in question. A genetic null allele may be both a protein null and an RNA null, but may also express normal levels of a gene ...
What does heterozygous mean? Heterozygous refers to having two different alleles for a specific gene. 12 How do heterozygous genotypes affect health? Heterozygous individuals may be carriers of a disease but typically do not show symptoms if one allele is dominant and healthy. 9 Can homozygosity be...
