  1. Quiz Review – Meiosis and Genetics

  2. Meiosis I MeiosisII 1)Cell division process that cuts the chromosome number in half • Meiosis 2)What is the only type of cell produced by this process? • Gametes (egg and sperm) 3)Term for half of the normal chromosome number (1n) produced by the previous process • Haploid 4) What is the haploid number of human chromosomes? • 23

  3. 5) Process where homologous chromosomes line up and exchange genes to increase Diversity Crossing over

  4. 6) Process where a sperm and egg unit. • Fertilization (produces a zygote)

  5. from mom from dad child too much! meiosis reduces genetic content 7) Why is it necessary for gametes to be produced by meiosis instead of mitosis? Meiosis cuts the chromosome number in half so that when fertilization occurs (Egg and sperm unite), it adds back up to the diploid number. (23 chromosomes in egg + 23 chromosomes in sperm = 46 chromosomes in zygote) If the gametes were produced by mitosis, the chromosome number would double each generation. The right number!

  6. 8) Meiosis produces (2 or 4) daughter cells, that are (different or identical), (haploid or diploid), and are used to make all (somatic cells or gametes) • 4, • different, • haploid, • gametes

  7. 9) Study of heredity • Genetics • 10) “Father” of Genetics • Gregor Mendel • 11)Single, alternate form of a gene • Allele • 12) Genetic makeup of an organism • Genotype • 13) Physical trait of an organism (i.e. eye color, hair color) • Phenotype • 14) Term for 2 like alleles (i.e. TT or tt) • Homozygous • 15) Term for 2 unlike alleles (Tt) • Heterozygous

  8. 16) The allele for tongue rolling (R) is dominant to non-tongue rolling (r). • What is the genotype of a parent that is • i)homozygous dominant • i. RR • ii)heterozygous • ii.Rr • iii)homozygous recessive • iii. Rr • What is the phenotype of a parent that is: • i)homozygous dominant • i) Tongue roller • ii)heterozygous • ii) Tongue roller • iii)homozygous recessive • iii) Non-tongue roller

  9. 17) If two individuals who are heterozygous for the trait have children, what is the probability the child could roll his/her tongue? • Rr X Rr • 75% chance the child could roll his/her tongue
