Mutation and sexual reproduction lead to genetic variation in a population. As a basis for understanding this concept:
- 2g. Students know how to predict possible combinations of alleles in a zygote from the genetic makeup of the parents.
A multicellular organism develops from a single zygote, and its phenotype depends on its genotype, which is established at fertilization. As a basis for understanding this concept:
- 3a. Students know how to predict the probable outcome of phenotypes in a genetic cross from the genotypes of the parents and mode of inheritance (autosomal or X-linked, dominant or recessive).
- 3b. Students know the genetic basis for Mendel’s laws of segregation and independent assortment.
- 3c. ***Students know how to predict the probable mode of inheritance from a pedigree diagram showing phenotypes.
