Quick Answer: What allele can be masked?

an allele that can be masked, or hidden, by tht presence of another allele is classified as recessive
both alleles influence the phenotype, causing a blended appearance incomplete dominance
an organism that has two different alleles for a particular trait hybrid

What alleles can be covered up or masked?

Genetics Vocabulary Review

alleles alternate forms of a gene
recessive allele the allele that is masked or covered up when the dominant allele is present
dominant allele the allele whose trait always shows up if the allele is present
probability the likelihood that a particular event will occur

What is a trait that can be masked?

recessive trait. trait of an organism that can be masked by the dominant form of a trait.

Which type of allele expression is masked by other alleles?


If the alleles are different, the dominant allele usually will be expressed, while the effect of the other allele, called recessive, is masked. In codominance, however, neither allele is recessive and the phenotypes of both alleles are expressed.

What are multiple alleles examples?

Two human examples of multiple-allele genes are the gene of the ABO blood group system, and the human-leukocyte-associated antigen (HLA) genes. The ABO system in humans is controlled by three alleles, usually referred to as IA, IB, and IO (the “I” stands for isohaemagglutinin).

What do multiple alleles mean?

: an allele of a genetic locus having more than two allelic forms within a population.

How many alleles are in a gene?

An allele is one of two or more versions of a gene. An individual inherits two alleles for each gene, one from each parent. If the two alleles are the same, the individual is homozygous for that gene.

What is a masked gene called?

A gene that masks the phenotypic effect of another gene is called an epistatic gene; the gene it subordinates is the hypostatic gene. … The presence of epistatic genes explains much of the variability seen in the expression of such dominantly inherited human diseases as Marfan syndrome and neurofibromatosis.
