PORTAGE GENETICS MODULE 1 WITH
COMPLETE SOLUTIONS
What is an example of selective breading? - ANSWER-fossils of dogs showing they
were from wolf ancestors (humans and wolfs were competitors, then turned to
companions)
What is selective breading? - ANSWER-a process used by humans that allows only
those animals with desired characteristics to produce the next generation of organisms.
Who proposed the idea of epigenesis - ANSWER-William Harvey
define epigenesis - ANSWER-concept that a fertilized human egg undergoes
developmental events that lead to the formation of a human
Define preformation - ANSWER-a fertilized egg contained a tiny version of a fully
developed adult (called a homunculus)
What organism was one of the earliest models in genetics? - ANSWER-fruit flys
genetic mutations results in different: - ANSWER-alleles
What are wild type alleles - ANSWER-prevalent alleles in a population (normal genetics)
phenotype - ANSWER-An organism's physical appearance, or visible traits.
genotype - ANSWER-the pair of alleles that make up a trait
Who introduced the idea of cell theory (2) - ANSWER-Matthias Schleiden and Theodor
Schwann
define spontaneous generation - ANSWER-the idea that living things can spontaneously
generate from non living components
Define cell theory - ANSWER-All living things are composed of cells and come from
preexisting cells
define homologous chromosomes - ANSWER-Pairs of chromosomes
Who confirmed that DNA carried genetic material ? (3) - ANSWER-Avery, MacLeod,
McCarthy
