Honors Biology Unit 2 Review!
Chapter 5
Can you diagram the cell cycle, name the parts and what occurs?
Could you diagram a cell and the stages of mitosis with a cell that has 3 chromosomes? 4? 5?
Can you name and describe three different ways meiosis contributes to genetic variety?
Can you describe the similarities and differences between: ~mitosis/meiosis ~meiosis I/meiosis II ~cytokinesis in plants and animals

Can you name Mendel's three laws and describe them?
Can you do Punnett squares with one trait and give genotypic and phenotypic results? With two or three traits?
Can you differentiate between: ~somatic cell/gamete ~phenotype/genotype ~homo/heterozygous ~blood types ~incomplete, co-dominance & polygenic inheritance?
Can you do explain why a test cross is necessary?
Honors Bio Unit 2 Review 1 And, if all their offspring were "tasters" then the unknown parent is probably a...
A heterozygote B homozygote - dominant
C homozygote - recessive
Cross two wavy-haired people and give the predicted genotype and phenotype ratios of their children.
Do the practice problems in the chapter and at the end of the chapter ~ answers in book!
October 27, 2011 2 So, if we had someone who could taste PTC paper, a dominant trait, who would we cross them with to see if they were a heterozygote or a homozygote?
A
non-taster
B
taster
Cross a normal vision man with a woman who is a carrier/heterozygote female for vision.

Can you explain what a karyotype is? Can you tell "why" karyotypes are made?
Can you list and explain some issues with chromosome numbers?
Can you list and explain some issues with chromosomal mutations (structural issues)?
Can you differentiate between the three types of inheritance patterns: autosomal dominant, autosomal recessive and X(sex)linked?
Can you list and explain some ways to check for genetic disorders?
Can you list and explain some current genetic studies and treatment plans?
Honors Bio Unit 2 Review 1 What stage of mitosis do they use the chromosomes from to do a karyotype?
