Question

practice identifying dominant and recessive alleles
a heterozygous genotype will only show the dominant trait, because a dominant allele always covers or masks a
recessive genotype is
(need a refresher? watch the video on heterozygous and homozygous)

Explanation:

The problem is about identifying the phenotype of a heterozygous genotype in the context of dominant and recessive alleles, which relates to genetics, a subfield of Biology (Natural Science). A heterozygous genotype has one dominant and one recessive allele. Since the dominant allele masks the recessive one, the phenotype expressed is the dominant trait. For example, if the dominant allele is for a tall trait (T) and recessive for short (t), a heterozygous (Tt) genotype would show the tall phenotype.

Answer:

The phenotype of a heterozygous genotype is the dominant trait (e.g., if dominant is for tall, the phenotype is tall).
