Is heterozygous the dominant trait? Anorganism with two dominant alleles for a traitis said to have a homozygous dominant genotype. Using the eye color example, this genotype is written BB. An organism with one dominant allele and one recessive allele is said to have a heterozygous genotype. ...
Allele pairs are described using the terms heterozygous and homozygous. Every diploid entity comprises two copies of each of the genes, wherein each could be recessive or dominant. Dominant alleles are expressed to give rise to a phenotype, whereas the recessive alleles remain unexpressed. Both the...

A singleDOMINANTgene can manifest itself in a heterozygous person. Recessive genes are only manifest ...
However, a recessive trait in some genes can only be expressed when an organism's genotype is homozygous recessive where there are no dominant alleles present in the genotype.Heterozygous Example Complete Dominance, Incomplete Dominance, and Codominance Heterozygous Mutation Lesson Summary Register to ...
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 Their Representation: In genetics, alleles are differ...
When you inherit different alleles, the dominant allele is the one that is expressed in your body. For example, if you are heterozygous for the hair color gene, you might have one copy of the blonde hair allele and one copy of the brown hair allele. Because the brown hair allele is dom...
Definition Humans have two alleles on homologous chromosomes for each gene or trait, one from their mother and one from their father. If the allele inherited from the mother is different from the allele inherited from the father, then the individual is heterozygous for that trait or gene. ...
Alternative forms of a given gene are called alleles, and they can be dominant or recessive. When an individual has two of the same allele, whether dominant or recessive, they are homozygous. Read Homozygous vs. Heterozygous | Definition & Differences Lesson ...
Dominant traits like whether you can roll your tongue or have a genetic predisposition to developing Huntington's disease only require one dominant allele to express. This means that people with homozygous dominant alleles (AA) and heterozygous alleles (Aa) express those traits, but people with hom...
Dominant missense variants in MYBPC1 encoding slow Myosin Binding Protein-C (sMyBP-C) have been increasingly linked to arthrogryposis syndromes and congenital myopathy with tremor. Herein, we describe novel compound heterozygous variants – NM_002465.4:[c.2486_2492del];[c.2663A > G] – present...
