GUARANTEED PASS
Which ancient idea about inheritance came from Hippocrates? - Answers -Pangenesis
What ancient idea about inheritance came from Aristotle? - Answers -Form +
Potentiality = Actuality
What ancient idea about inheritance came from the Bible? - Answers -Experiences of
the mother resulted in changes of the offspring (the story of Jacob, Genesis)
Hybridizations between quite different animals yielded offspring that are ____________
in appearance. - Answers -Intermediate
Up until the 19th century people believed that _________ characteristics was one cause
of _________. - Answers -Acquired (characteristics was one cause of) inheritance.
Genetic __________ was an idea behind essentialism. - Answers -Purity
What is preformationism? - Answers -A formerly-popular theory that organisms develop
from miniature versions of themselves
What is eugenics? - Answers -The ability to create form.
The study of changes in organisms caused by modification of gene expression rather
than alteration of the genetic code itself.
An outdated theory that the phenotype of an offspring was a uniform blend of the
parent's phenotypes. - Answers -blending inheritance
Gregor Mendel (1822-1884) - Answers -Investigated inheritance in pea plants by
observing differences in various traits of the plants from generation to generation,
leading to the idea that information needed to build an organism is packaged into units
associated with specific traits.
What was Mendel's observation of "segregation of traits "? - Answers -Uniform parents
could give differing progeny; can be considered the opposite of hybridization
Mendel laid the foundation for ______ ______ _____. - Answers -Modern experimental
genetics.
, According to Mendel's particulate model of inheritance, hereditary factors behaved as
distinct, indivisible entities, or __ __ __, and not as continuous influences or __ -
Answers -atoms of inheritance
fluids
Mendel observed, but did not name: - Answers -Independent assortment, or the
independence of heritance patterns of different genes
Mendel's work gained the interest of a botanist ___ ___, who suggested that _______. -
Answers -Karl Negeli
Mendel try to repeat his work with a different plant, "Hawkweed".
Why didn't Mendel's experiments with Hawkweed yield successful results that he had
seen when experimenting with other plants? - Answers -Hawkweed is asexual.
What kind of model of inheritance was Darwin's Pangenesis? - Answers -A particulate
model
How did Darwin's model of inheritance differ from that of Mendel's? - Answers -
Darwin's pangenesis had particulate gemmules (rather than particulate genes).
But Darwins's gemmules changed over an individual's life, unlike Mendel's particles.
August Wiesmann's Germplasm Theory distinguished between: - Answers -germplasm,
the precursor cells of sex cells; and
somatoplasm, the rest of the cells of the body
How did Wiesmann test inheritance models of his day? - Answers -He raised mice, cut
off their tails, let them breed, cut off the tails of their progeny (having measured the tails
prior), if acquired inheritance was true, the tails should become shorter and shorter, but
did this did not happen.
If there's some _______ in the germplasm, it's passed along. The somatoplasm
mutations had _______ passed along to offspring. These mutations ______
communicate information to the germplasm. - Answers -Mutation (in the germplasm)
Nothing (passed along).
Don't (communicate information).
Like Mendel, Weismann's theory of ____ also involved hereditary particles rather than
____. - Answers -Inheritance (also involved...)
