Addition Rule of Probability Correct Answers Used to
determine the probability that at least one of two mutually
exclusive events will occur.
P(A or B) = P(A) + P(B) - P(AB)
Alfred Wallace (1823-1913) Correct Answers "Father of
Biogeography," was the first to propose that animal species have
"geographies"
Alternate forms of a gene are called _______. Correct Answers
alleles
amino acids Correct Answers building blocks of proteins
analogy Correct Answers similarity of function and superficial
resemblance of structures that have different origins (e.g. wings
of a fly, moth and bird)
,Anaphase Correct Answers Phase of mitosis in which the
chromosomes separate and move to opposite ends of the cell
ancestral characteristics Correct Answers characteristics that
have arisen in organisms as a result of common evolutionary
descent
assortative mating Correct Answers the type of mating that
occurs when an organism selects a mating partner that resembles
itself
At metaphase I, homologous chromosomes are connected only
at what structures? Correct Answers Chiasmata
autosomal dominant inheritance Correct Answers inheritance
of a dominant gene mutation on an autosome
autosomal inheritance Correct Answers The inheritance
patterns that occur when genes are located on autosomes rather
than on sex chromosomes.
Autosomal Recessive Inheritance Correct Answers two
recessive alleles must be present for trait to be displayed
Avery, McCarty, MacLeod (1944) Correct Answers biological
researchers who identified DNA as the likely transforming
principle in Griffith's experiment.
bacterial transforming principle Correct Answers an
experiment proposed by Frederick Griffith in 1928 which
suggested that a "transforming principle" from a heat-killed
, virulent Pneumococcus strain can transform a non-virulent strain
into a pathogenic one.
Besides growth, what must happen before a cell divides?
Correct Answers DNA replication
Binomial Distribution Correct Answers The probability
distribution of X with parameters n and p
carrier Correct Answers A person who has one recessive allele
for a trait, but does not express the trait.
cell cycle Correct Answers The regular sequence of growth and
division that cells undergo to produce two new daughter cells
central dogma Correct Answers theory that states that, in cells,
information only flows from DNA to RNA to proteins
Chargaff's Rule Correct Answers A=T and C=G
Charles Darwin (1809-1882) Correct Answers English
naturalist who postulated a theory of evolution by natural
selection.
chiasmata Correct Answers X-shaped regions where crossing
over occurred.
chromosomes Correct Answers a threadlike structure of nucleic
acids and protein found in the nucleus of most living cells,
carrying genetic information in the form of genes.
