What occurs when both alleles for a gene are expressed equally?

What is it called when both alleles are identical?

Genotypes are described as homozygous if there are two identical alleles at a particular locus and as heterozygous if the two alleles differ. Alleles contribute to the organism’s phenotype, which is the outward appearance of the organism. Some alleles are dominant or recessive.

When both alleles are expressed equally in the heterozygote?

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 two alleles are equally expressed this is called quizlet?

Terms in this set (79) Compare and contrast the terms codominance and incomplete dominance. When both alleles are equally expressed in the phenotype codominance is occurring.

When both the alleles are identical they are said to be homozygous?

An organism in which both the genes (allele) for a given character are identical is said to be homozygous.

What does homozygosity mean?

Homozygous describes the genetic condition or the genetic state where an individual has inherited the same DNA sequence for a particular gene from both their biological mother and their biological father. It’s often used in the context of disease.

What occurs when both alleles are expressed equally in the phenotype of the heterozygous?

Codominance occurs when both alleles are expressed equally in the phenotype of the heterozygote. The red and white flower in the figure has codominant alleles for red petals and white petals. Codominance.

When two alleles express equally in a heterozygous individual then the following is true?

When two alleles express equally in a heterozygous individual then the following is true: One allele is not completely dominant over the other.
