Exam 4 1) Outline the behavior of chromosomes during different stages of the cell cycle and Meiosis. 2) Be able to describe how the number of chromosomes, the number of homologous pairs, and amount of DNA varies in different stages of the cell cycle and Meiosis. 3) Describe the relationship between the ploidy of a cell and how many homologous chromosomes are present in a cell. 4) Be able to apply the terms homozygous, heterozygous, hemizygous, phenotype, genotype, gene and allele in genetics problems 5) Be able to determine the genetic make-up of gametes an individual can produce given the individual’s genotype. 6) Be able to determine the phenotypic and genotypic rations of the offspring from any monohybrid cross, including crosses involving complete dominance, incomplete dominance, co-dominance, sex linkage.
