What type of trait has a heterozygous phenotype that is a mixture of the two homozygous trait?
This type of relationship between alleles, with a heterozygote phenotype intermediate between the two homozygote phenotypes, is called incomplete dominance.
What is the term for when a heterozygous genotype produces a phenotype that is intermediate between the dominant and recessive phenotypes?
Incomplete Dominance. a pattern of inheritance in which the heterozygous phenotype is intermediate between the two homozygous phenotypes.
What is it called when two alleles are mixed?
= Codominance is a relationship between two versions of a gene. Individuals receive one version of a gene, called an allele, from each parent. If the alleles are different, the dominant allele usually will be expressed, while the effect of the other allele, called recessive, is masked.
What is a heterozygous allele combination?
When you’re heterozygous for a specific gene, it means you have two different versions of that gene. The dominant form can completely mask the recessive one, or they can blend together. In some cases, both versions appear at the same time. The two different genes can interact in various ways.
What is heterozygous phenotype?
A heterozygous individual is a diploid organism with two alleles, each of a different type. Individuals with alleles of the same type are known as homozygous individuals. … Incomplete dominance, in contrast, produces a heterozygous phenotype that is somewhere between the dominant and recessive phenotypes.
Is heterozygous a genotype or phenotype?
If an individual inherits two identical alleles, their genotype is said to be homozygous at that locus. However, if they possess two different alleles, their genotype is classed as heterozygous for that locus. Alleles of the same gene are either autosomal dominant or recessive.
What is the term heterozygous mean?
(HEH-teh-roh-ZY-gus JEE-noh-tipe) The presence of two different alleles at a particular gene locus. A heterozygous genotype may include one normal allele and one mutated allele or two different mutated alleles (compound heterozygote).
What is it called when more than one allele is expressed in a heterozygous individual?
Incomplete dominance is the expression of two contrasting alleles such that the individual displays an intermediate phenotype. Codominance is a variation on incomplete dominance in which both alleles for the same characteristic are simultaneously expressed in the heterozygote.
When heterozygous genotypes produce an intermediate trait this type of genetic interaction is termed?
Incomplete dominance is a situation in which two alleles in the heterozygote have an intermediate phenotype. In codominance, both alleles exert their effects independently in the heterozygote.
What is heterozygous recessive?
An organism can be homozygous dominant, if it carries two copies of the same dominant allele, or homozygous recessive, if it carries two copies of the same recessive allele. Heterozygous means that an organism has two different alleles of a gene.
What is the difference between a heterozygous phenotype produced by incomplete dominance and a heterozygous phenotype produced by Codominance?
What is the difference between a heterozygous phenotype produced by incomplete dominance and a heterozygous phenotype produced by codominance? In incomplete dominance, the heterozygous phenotype is somewhere between the two homozygous phenotypes. In codominance, the heterozygous phenotype shows both traits.
Is heterozygous dominant?
Difference between homozygous and heterozygous
Unlike homozygous, being heterozygous means you have two different alleles. You inherited a different version from each parent. In a heterozygous genotype, the dominant allele overrules the recessive one. Therefore, the dominant trait will be expressed.
