Question

The term that describes the allele that determines the phenotype of an individual organism when two different copies are present in the genotype is?

A. Recessive
B. Nucleus
C. Dominant
D. Eukaryotic

Answer 1

The allele that determines the phenotype in the presence of another, different allele is known as the dominant allele, which masks the effect of the recessive allele unless the latter is present in a homozygous recessive genotype.

Step-by-step explanation:

The term that describes the allele that determines the phenotype of an individual organism when two different copies are present in the genotype is known as the dominant allele. Some alleles are dominant, whereas others are recessive. An organism with at least one dominant allele will display the effect of the dominant allele. For example, in humans, if an individual receives one allele for freckles, which is dominant, and one for no freckles, which is recessive, the individual will show the freckles. The visible or detectable characteristic caused by the recessive allele will only be observed if the organism has two recessive alleles (homozygous recessive), since the presence of a dominant allele would mask the expression of the recessive allele in the phenotype.

Answer 2

A. Recessive

Step-by-step explanation:

Only answers A and C can be used to describe an allele, so B and D can't be it. If the allele was dominant, only one copy would be necessary for the phenotype to be expressed (ex. heterzygous green peas are still green, even though they carry a yellow allele). Therefore, since 2 copies are present for this phenotype, it must be recessive.
