Chapter 2 Gen Flashcards
Be able to explain briefly why the results and conclusions of Mendel’s
experiments with peas are relevant to all sexually reproducing organisms
Explain the advantages of using pea plants in Mendel’s experiments
(many varieties, pure-breeding, availability of two clear traits per character,
breeding capabilities, etc)
Be able to completely describe Mendel’s monohybrid and dihybrid crosses
upto F2 generation including the ratios of progeny expected
Explain and apply the Law of equal segregation of alleles for a particular
character and the experiments of Mendel that allow us to reach this
conclusion
Explain and apply the Law of independent assortment of alleles governing
characters that are unlinked (i.e. lie on different non-homologous
chromosomes) and the experiments of Mendel that allow us to reach this
conclusion
Two ways to test the genotype of the F1 progeny in Mendel’s experiments
Two ways to test the genotype of the F2 progeny in Mendel’s experiments
Assign allelic symbols for crosses with novel traits to be able to analyze related crosses
Test cross
Apply the multiplication method and fork-line method
Independent assortment achieved for a species
Accurate description of a Punnett square
It tells us the probability with which a particular genotype and phenotype can be expected to appear in the offspring
Given the parent genotype, predict the number of gametes: AaBbCc
2x2x2= 8 gametes, because heterozygotes give off 2
