Alan Dewey
Wabasso High School
OBJECTIVES
1. In the context of a monohybrid cross, apply the terms phenotype, genotype, allele, homozygous and heterozygous.
2. Use concepts from Mendel’s Laws of Segregation and Independent Assortment to explain how sorting and recombination (crossing over) of genes during sexual reproduction (meiosis) increases the occurrence of variation in a species.
3. Use the processes of mitosis and meiosis to explain the advantages and disadvantages of asexual and sexual reproduction.
