BIOD 210 GENETICS MODULE 1 7 COMPLETE
STUDY GUIDE WITH SOLVED QUESTIONS
◉ William Harvey.
Answer: English physician and scientist who proposed epigenesis
◉ Preformation Theory.
Answer: The idea that a fertilized egg contained a tiny version of a
complete adult (homunculus). Epigenesis contradicted this idea
◉ Homunculus.
Answer: A tiny version of a completely developed adult
◉ Cell Theory.
Answer: (1830s) proposed that all living organisms were composed
of organized structures called cells, and that these cells were derived
from identical precursor cells
◉ Matthias Schleiden and Theodor Schwann.
Answer: Proposed cell theory
◉ Spontaneous Generation.
, Answer: The theory that living things could spontaneously generate
from non living components; debunked by cell theory
◉ Natural Selection.
Answer: Proposed by Charles Darwin in 1859, this theory posited
that more offspring were produced than an environment could
support, so the offspring that inherited the most desirable traits for
a certain environment would ultimately survive
◉ Gregor Mendel.
Answer: Augustinian monk and botanist whose experiments in
breeding garden peas led to his eventual recognition as founder of
the science of genetics (1822-1884). Explained the development of
hybrids within pea plants and basic foundations of trait
transmission.
◉ Genetics.
Answer: The study of heredity; coined in early 1900s, focuses
primarily on the understanding of genes and how they contribute to
the passing of traits
◉ Chromosomal Theory of Inheritance.
Answer: Proposed in 1910s, showed that both heredity and
development depended on the passing of genetic information via
genes that were contained in chromosomes
