Answer:
1.Patterns of inheritance in humans include autosomal dominance and recessiveness, X-linked dominance and recessiveness, incomplete dominance, codominance, and lethality. A change in the nucleotide sequence of DNA, which may or may not manifest in a phenotype, is called a mutation.
2.Working with garden pea plants, Mendel found that crosses between parents that differed for one trait produced F1 offspring that all expressed one parent's traits. The traits that were visible in the F1 generation are referred to as dominant, and traits that disappear in the F1 generation are described as recessive.
3.In the F2 generation the recessive trait is shown because of an absence of the dominant allele. Explain how a trait might seem to "disappear" for a generation, and then "reappear" in the following generation. A purebred has the same gene for a trait and a hybrid is a cross between two different genes.
4.NO
