Homozygous means that both copies of a gene at a locus are the same while heterozygous means that the copies do not match. Two dominant alleles (AA) or two recessive alleles (aa) are homozygous. One dominant allele and one recessive allele (Aa) is heterozygous. So Many Chromosomes Humans a...
A person with blonde hair, however, must be homozygous for the hair color gene, because the blonde hair allele is recessive. This means there need to be two copies of the blonde hair allele for that trait to be expressed. The Greek roothomo- means "same" and the prefixhetero-means "oth...
As such, homozygous dominant means that the organism has two dominant alleles for that particular genetic trait. If an organism is homozygous recessive, then it has two recessive alleles. When a homozygous organism reproduces, it can only pass on one form of the allele to any offspring as it...
When an animal is homozygous for a trait, the trait can be expressed in different ways as a result of other alleles which have an influence on development. When an animal is homologous recessive, it means that it has inherited two copies of a recessive gene. People with blue eyes are an...
Heterozygous(and its less common formheterozygotic) means “relating to a cell that has two different alleles for a particular gene at corresponding positions on homologous chromosomes.” Remember, a chromosome carries genes in linear order; a gene is a segment of code that dictates what trait wi...
Heterozygous means that an organism has two different alleles of a gene. For example,pea plants can have red flowersand either be homozygous dominant (red-red), or heterozygous (red-white). If they have white flowers, then they are homozygous recessive (white-white). Carriers are always heter...
Any genotype where two of the same allele are inherited is called homozygous because the prefix "homo" means same. Consider the following example. The trait of eye color is coded for several genes. Each of these genes have different alleles that can be inherited, such as an allele for blue...
The correct Answer is:C Step-by-Step Solution: 1. Understanding Dominant Genes: A gene is termed dominant if it can express its trait in both homozygous and heterozygous conditions. This means that the dominant gene will show its effect even when only one copy is present. 2. Alleles and ...
Basically, it means that a horse has two copies of the same trait in its genetic makeup. But the important part of that is that if a horse is homozygous for a dominant form of a trait, then EVERY foal that horse produces will carry that trait. So for a homozygous roan mare or stall...
When the loci in the matching chromosomes bear the same alleles, it is described as homozygous. It means that the alleles code for the same trait. A‘homozygous’ organism for a particular trait is described to possess either a pair of dominant alleles (e.g. AA) or a pair of recessive ...
