Presentation Transcript

  1. Independent Assortment and Segregation Describe independent assortment and segregation and explain the relevance of these to variation.

  2. Variation in Meiosis Meiosis provides variation – it produces 4 unique sex cells. The processes WITHIN Meiosis that produce variation are: 1. Independent Assortment 2. Crossing Over 3. Segregation

  3. Independent Assortment Independent assortment is a basic principle of genetics developed by a monk named Gregor Mendel in the 1860's This principle states that the alleles for a trait separate when gametes are formed. • Worksheet • Animation • http://www.sumanasinc.com/webcontent/animations/content/independentassortment.html

  4. Segregation • the paired alleles of the genes, which determine the traits of an organism, are segregated (separated) during gamete formation so that only one allele passes into each gamete. • http://www.yteach.co.uk/page.php/resources/view_all?id=allele_diploidy_haploidy_heterozygote_homozygote_homologous_chromosomes_phenotype_genotype_gene_locus_meiosis_dominant_alleles_recesive_alleles_test_cross_page_3&from=search

  5. Segregation occurring • Who can spot the crossing over happening?

  6. WB p90 In your book – answer- • How does Segregation provide variation? • How does Independent Assortment provide variation?
