Final Answer:
Traits "skipping a generation" can be explained by Mendel's laws of inheritance, specifically the principles of dominant and recessive alleles and the presence of carriers.
Step-by-step explanation:
Mendel's experiments with pea plants revealed the existence of dominant and recessive alleles governing the inheritance of traits. Traits "skipping a generation" often involve the presence of a recessive allele that is not expressed in one generation but can reappear in the next. When an individual inherits one dominant allele and one recessive allele (heterozygous), the dominant trait masks the expression of the recessive trait, leading to the absence of the trait in that generation. However, the recessive trait can resurface if two carriers (heterozygous individuals) have offspring with the same recessive allele, resulting in a homozygous recessive individual expressing the trait.
