A carrier is a person who has __________?
A; one recessive and one dominant allele for a trait.
B; two recessive alleles for a trait.
C; two dominant alleles for a trait.
D; more than two alleles for a trait.
Answer is A :)
To determine the correct answer, let's break down the options and their meanings:
A. One recessive and one dominant allele for a trait: This refers to an individual who has one copy of a recessive allele and one copy of a dominant allele for a specific trait. It does not necessarily make them a carrier of the trait in question.
B. Two recessive alleles for a trait: This option suggests that a carrier has two copies of the recessive allele for a certain trait. In genetics, being a carrier typically means having one copy of a recessive allele and one copy of a dominant allele, so this option does not fit the definition of a carrier.
C. Two dominant alleles for a trait: This option describes an individual who has two copies of the dominant allele for a particular trait. Again, carriers usually have one dominant and one recessive allele rather than two dominant alleles, so this is not the correct choice.
D. More than two alleles for a trait: An allele is a variant form of a gene. In humans, each individual typically has two alleles for each gene, one inherited from each parent. Therefore, more than two alleles for a trait is not a characteristic of a carrier.
Based on the explanations provided, neither option A, B, C, nor D is accurate. Therefore, none of the given options correctly completes the statement.
