50 *crossing over during prophase 1 *random orientation of *chromosomes during metaphase 1 *sexual reproduction Potpourri

10 When does crossing over occur and why? Meiosis

*Prophase 1 when homologous chromosomes undergo synapsis and form a tetrad *for genetic diversity in gametes 10 Meiosis

20 What are the products of meiosis? Meiosis

*4 genetically different haploid cells *Sperm/egg cells (gametes) 20 Meiosis

30 Why do homologous chromosomes pair up during prophase 1 of meiosis but never in mitosis? Meiosis

*To reduce the number of chromosomes (stays the same in mitosis) *to enable crossing over to occur (stays the same in mitosis) 30 Meiosis

40 What is the law of segregation? Meiosis

*separation of chromosomes during anaphase 1 of meiosis. *ensures gametes only have one copy of each allele 40 Meiosis

50 What is the law of independent assortment? Meiosis

50 Chromosomes with different alleles sort independently along the metaphase plate of meiosis 1. Meiosis

10 Meiosis What term is used to describe chromosomes that carry the same genes, just different versions of those genes?

Homologous Chromosomes 10 Meiosis

20 When do homologous chromosomes pair up? What happens as a results? Meiosis Meiosis

Prophase 1- synapsis occurs, a tetrad forms, enabling crossing over. 20 Meiosis Meiosis

30 What is required before meiosis can occur? Meiosis Meiosis

30 *DNA replication in a diploid cell.

40 Identify the phase of meiosis and explain. Meiosis Meiosis

40 Anaphase 1; *homologous chromosomes separate into individual chromosomes (sister chromatids) *cell is now haploid

50 A cat has a diploid number of 38. What would the number of chromosomes be in a cell in telophase 1 of meiosis in this cat? What would it look like? What would the number of chromatids be in a cell in telophase 2 of meiosis in this cat? What would it look like? A cat has a diploid number of 38. What would the number of chromosomes be in a cell in telophase 1 of meiosis in this cat? What would it look like? What would the number of chromatids be in a cell in telophase 2 of meiosis in this cat? What would it look like? Meiosis Meiosis

30 After mating a brown bunny with a white bunny, the offspring are all brown. What are the genotypes of the parents? The offspring?

30 Genetics 1 Parents- BB X bb Offspring- Bb

40 Genetics 1 Since each pair of alleles segregate separately from other pairs of alleles, Mendel created…

40 Genetics 1 *The Law of Independent Assortment *supported by homologous chromosome random sorting during metaphase 1 of meiosis.

50 Genetics 1 Because alleles separate when homologous chromosomes split in anaphase 1 of meiosis, this supports Mendel’s…
