What is an allele that is covered up by another allele called?

Question

Please help! I went through my whole science txtbook and I couldn't find the answer!

Theres many there that might have the concept I'll list off the site

alleles whose summed effect is that of lethality for example, four alleles each of which would be lethal 25% of the time (or to 25% of their bearers), are equivalent to one lethal allele.

Codominant alleles occur when rather than expressing an intermediate phenotype, the heterozygotes express both homozygous phenotypes. An example is in human ABO blood types, the heterozygote AB type manufactures antibodies to both A and B types.

An allele is a gene that has more than one form. Each of the forms is referred to as an allele. For example, the gene for red flowers and the gene for white flowers are two different alleles.

It's likely referring to the dominant trait covering up the recessive.

heterozygous

Answer 3

You are referring to what is more commonly called a recessive allele. The dominant allele (the dominant gene) is expressed while the recessive one is not. If both genes are recessive, then the recessive trait is expressed.
