What does masking an allele mean?
Individuals receive one version of a gene, called an allele, from each parent. If the alleles are different, the dominant allele will be expressed, while the effect of the other allele, called recessive, is masked.
What is a masking gene?
Gene masking, essentially, is a binary encoded genetic algorithm that generates a template used to represent a chromosome, referred to as a mask, while the individual bits at different indices in the chromosome are annotated as genes.

What allele means?
An allele is a variant form of a gene. Some genes have a variety of different forms, which are located at the same position, or genetic locus, on a chromosome. … Genotypes are described as homozygous if there are two identical alleles at a particular locus and as heterozygous if the two alleles differ.
Why do some alleles mask others?
When the pairing of two alleles results in a blended or intermediate outcome, you have an instance of incomplete dominance. … In this scenario there is no truly dominant allele, yet the presence of the two different alleles within the same organism results in a masking of the expression of both alleles.
Why does a dominant allele mask a recessive allele?
If an organism is heterozygous for a specific gene, which allele will be expressed? In this case, the dominant allele will mask the other one, which is referred to as the recessive allele. The protein that the dominant allele codes for will be produced, which will dictate the traits the organism has.
What term describes an allele that is masked or covered up by another allele?
Recessive. The general term for an allele that is masked in the phenotype by the presence of another allele.
Are alleles inherited?
Although an individual gene may code for a specific physical trait, that gene can exist in different forms, or alleles. One allele for every gene in an organism is inherited from each of that organism’s parents. … Alleles produce phenotypes (or physical versions of a trait) that are either dominant or recessive.
What is it called when one allele completely masks another?
In complete dominance, the effect of one allele in a heterozygous genotype completely masks the effect of the other. The allele that masks the other is said to be dominant to the latter, and the allele that is masked is said to be recessive to the former.
What are 2 copies of the same allele?
An organism in which the two copies of the gene are identical — that is, have the same allele — is called homozygous for that gene. An organism which has two different alleles of the gene is called heterozygous.
