Study Guide?Mendel and reduction class (+ both(prenominal) mitosis) 1. Be able to do a monohybrid cross. Example: Hh x hh 2. kip down heterozygous vs. homozygous 3. have discrepancy mingled with genotype and phenotype. 4. Know end between dominant and recessive. 5. Be able to do a dihybrid cross. Example:         H = dark-haired formula, h = non-hairy                           T = no teeth,          t = teeth What is the genotype of a man who is heterozygous for a hairy face and has teeth?          (answer: Hhtt) What ar in all told the possible allele combinations he can fail on through his gametes?                  (answer: Ht, Ht, ht, ht) 6. Know all about Mendels experiments. Started with true-breeding parental genesis ; crossed 2 of these plants with different propertys. F1 propagation = formulation; all had the same trait = dominant Self-pollinated F1 generationýoffspring = F2 generation; For every 3 plants that had the dominant trait, at that place was 1 with the recessive trait. 7. wherefore were pea plants a nice selection to use? 8. Know/apply Mendels Laws (dominance, segretation, independent assortment) 9. Meiosis (vs.

mitosis): befalls in gametes (sex cells); causes haploid cells (only 23 chromosomes); Two cell division stages make 4 young woman cells, homologues pair up, etc. Look at litotes pictures. Know whats passing play on in all(prenominal) phase. 10. What are Homologous pairs? What is crossover voter over? Why is it heavy for patrimonial variation? 11. What is haploid vs. diploid? 12. What is the cause of pubic louse? What are some encounter factors? 13. What are some mistakes that whitethorn occur in pupillary reflex and characteristics that result?
