A common example of this is eye color in humans. Brown is a dominant trait while blue is recessive. If a person has one allele for brown eye color and one for blue, the person’s eyes will be brown because brown is dominant. Such a person is said to be heterozygous for eye color....
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 t...
A child receives one allele for eye color from the mother and one from the father. When a child receives two alleles for brown eyes, the gene ishomozygous dominantfor that trait. If a child receives two different alleles for eye color, the gene for eye color isheterozygous. Gregor Mendel...
Humans can beheterozygousfor traits as well. To oversimplify it, you might inherit one copy of the “get freckles” allele and one copy of the “don’t get freckles” allele, meaning you may or may not get freckles as a result. When an organism isheterozygousfor a particular trait, how ...
Heterozygous animals have two different alleles, in which case only one of the alleles will be expressed. Hemizygous animals have inherited only one copy of an allele, with genetic information missing on the corresponding chromosome. Genetic inheritance is complicated, and it is rarely as simple as...
What is the genotype of a cross between homozygous dominant and homozygous recessive parents? What is the genotype of a homozygous individual for eye color, using B as the allele descriptor? Which allele is expressed in the dominant homozygous, heterozygous and homozygous recessive genotypes? What...
A homozygote is an organism that has inherited the same allele twice, once from each parent. The main signs that an organism is...
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. ...
A classic example of dominance isthe inheritance of seed shape (pea shape) in peas. Peas may be round (associated with allele R) or wrinkled (associated with allele r). In this case, three combinations of alleles (genotypes) are possible: RR and rr are homozygous and Rr is heterozygous....
In a simple example of the way in which dominant traits work, someone could have two parents who are heterozygous for brown and blue eyes. There is a 25% chance that the child will inherit the bb allele, making him or her blue-eyed. There is a 50% chance that the child will inherit...
