Mendel and MeiosisChapter Objectives:
Differentiate between body cells/autosomes and gametes/sex chromosomes
Explain how meiosis produces sex cells
Describe the patterns of inheritance that Mendel’s data revealed
Summarize Mendel’s laws of segregation and independent assortment
Describe how genes influence the development of traits
Explain how crossing over during meiosis increases genetic diversity.
Lesson Focus:6.1 Gametes have half the number of chromosomes that body cells have.Chromosome Numbers- how many chromosomes does each species have?
During meiosis, diploid cells undergo two cell divisions that result in haploid cells.
