An allele that is written as a lowercase letter.Group of answer choicesdominantrecessiveNext

In genetics, alleles are different forms of a gene that arise by mutation and are found at the same place on a chromosome. When an allele is represented by a lowercase letter, it indicates that it is recessive.

Here’s a brief explanation:

1. Dominant Alleles: These alleles are typically represented by uppercase letters. A dominant allele can mask the presence of a recessive allele.

2. Recessive Alleles: These are represented by lowercase letters. A recessive allele is only expressed in the phenotype if both alleles for a trait are recessive.

When considering the provided choices, the correct answer is recessive. This means that if an organism has one or more dominant alleles, the recessive phenotype will not be expressed unless the organism has two recessive alleles (homozygous recessive).
