Questions & Step-by-Step Solutions

In a genetic study, if a trait is controlled by a single gene with two alleles, where one allele is completely dominant over the other, what type of inheritance pattern is this?

Step 1: Understand that a trait is a characteristic that can be passed from parents to offspring.
Step 2: Know that genes are segments of DNA that determine traits.
Step 3: Recognize that alleles are different versions of a gene.
Step 4: Identify that in this case, there are two alleles for the trait.
Step 5: Learn that one allele is dominant, meaning it can mask the effect of the other allele.
Step 6: Conclude that when one allele completely masks the other, this is called complete dominance.
