Genetics

Study Guide?Mendel and Meiosis (+ some mitosis) 1. Be commensurate to do a monohybrid cross. Example: Hh x hh 2. hunch heterozygous vs. homozygous 3. Know discrepancy between genotype and phenotype. 4. Know difference between paramount and recessive. 5. Be able to do a dihybrid cross. Example:         H = hairy face, h = non-hairy                           T = no teeth,          t = teeth What is the genotype of a slice who is heterozygous for a hairy face and has teeth?          (answer: Hhtt) What ar in all told the possible allele combinations he rotter pass on through his gametes?                  (answer: Ht, Ht, ht, ht) 6. Know all near Mendels experiments. Started with true-breeding pargonntal genesis ; crossed 2 of these plants with different traits. F1 times = manifestation; all had the same trait = dominant autogamic F1 generationýo ffspring = F2 generation; For every 3 plants that had the dominant trait, there was 1 with the recessive trait. 7. Why were pea plants a good selection to use? 8. Know/apply Mendels Laws (dominance, segretation, item-by-item assortment) 9. Meiosis (vs.

mitosis): befalls in gametes (sex prison cells); causes haploid cells (only 23 chromosomes); Two cell division stages make 4 daughter cells, homologues pair up, etcetera Look at litotes pictures. Know whats going on in each phase. 10. What are Homologous pairs? What is crossing oer? Why is it important for patrimonial variation? 11. What is haploid vs. diploid? 12. What is the cause of cancer? What are some risk factors? 13. W hat are some mistakes that may occur in meio! sis and characteristics that will? (nondisjunction?Down Syndrome (= trisomy 21), Turners Syndrome (= XO) If you want to apprehend a full essay, fellowship it on our website: OrderEssay.net
