UNIT 7: Cell Division

UNIT 7: Cell Division. BIG IDEA: Cell division is the process in the body to create more cells and gametes . Chromosome Structure. Inside your nucleus are 3 billion nucleotides of DNA In order to fit it is coiled and packed into a complicated but organized structure. Chromosome Structure.

Sexual Reproduction

Sexual Reproduction. Heredity - passing down of characteristics ( genes ) Alleles - different forms of the same gene. Sexual Reproduction. Why sexual reproduction? shuffles alleles; new combinations provides genetic variation in species. Meiosis. Type of cell division

Meiosis Gamete Production

Meiosis Gamete Production. Mr. Young. Cells do not increase in size. They increase in number. Meiosis = process of nuclear division that reduces the chromosome number by half in new cells (gametes)

Meiosis: The reason why we are all unique

Meiosis: The reason why we are all unique. Meiosis occurs in two main phases Meiosis I Meiosis II. Meiosis: The reason why we are all unique. Big Ideas: The number of chromosomes per cell is cut in half from diploid to haploid Crossing over creates new combinations of alleles
