Lecture 1 Flashcards
Which statement does not describe a classical assumption most scientists and the general public had before the experiments of Kolreuter (1760s), T.A. Knight (1832) and Mendel?
Knight (1832)
-
Mendel
What were the findings of Josef Kolreuter (1760s) regarding patterns of inheritance?
What were the findings of T.A. Knight (1832) regarding patterns of inheritance?
What is the definition of true-breeding?
True-breeding is trying to reach only homozygous
Mendel, through his pea experiments, came up with the terms segregation, character, and traits. How are these words related to one another?
Male and female sexual organs are enclosed within a pea flower which Mendel used. He would self-pollinate and cross-pollinate to obtain his results. What is the difference between self-pollination and cross-pollination?
Which statement does not describe how Mendel found his phenotype and genotype results for the F1 and F2 generations?
Which statement describes the results of Mendel’s experiments (i.e. what did we learn from them being completed)?
What is the difference between a dominant and recessive trait?
the dominant trait you see
the recessive trait you see if the dominant is not present
What is the (a) genotypic and (b) phenotypic ratio of the offspring of a monohybrid cross of a heterozygous male and heterozygous female plant? H = tall and h = short
(a) HH, Hh, hh
(b) tall and short plant
What is the (a) genotypic and (b) phenotypic ratio of the offspring of a monohybrid cross of a homozygous short male and a heterozygous female plant? H = tall and h = short
(a) Hh, hh
(b) tall and short plant
What does it mean that Mendel discovered a “disguised ratio?”
F1 did not show white but F2 did when they were not original shown
- Helps with detecting diseases and incorrect genetics, so disused ration not physically
shown in the parent
