A recessive trait will be observed in individuals that are ________ for that

trait.CORRECT ANSWER: homozygous

Addition Rule of ProbabilityCORRECT ANSWER: 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 ANSWER: "Father of Biogeography," was the first to propose that animal species have "geographies"

Alternate forms of a gene are called _______.CORRECT ANSWER: alleles

amino acidsCORRECT ANSWER: building blocks of proteins

analogyCORRECT ANSWER: similarity of function and superficial resemblance of

structures that have different origins (e.g. wings of a fly, moth and bird)

• / 3

AnaphaseCORRECT ANSWER: Phase of mitosis in which the chromosomes separate

and move to opposite ends of the cell

ancestral characteristicsCORRECT ANSWER: characteristics that have arisen in

organisms as a result of common evolutionary descent

assortative matingCORRECT ANSWER: 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 ANSWER: Chiasmata

autosomal dominant inheritanceCORRECT ANSWER: inheritance of a dominant gene

mutation on an autosome

autosomal inheritanceCORRECT ANSWER: The inheritance patterns that occur when

genes are located on autosomes rather than on sex chromosomes.

Autosomal Recessive InheritanceCORRECT ANSWER: two recessive alleles must be

present for trait to be displayed

Avery, McCarty, MacLeod (1944)CORRECT ANSWER: biological researchers who

identified DNA as the likely transforming principle in Griffith's experiment.

bacterial transforming principleCORRECT ANSWER: 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 ANSWER: DNA

replication

• / 3

Binomial DistributionCORRECT ANSWER: The probability distribution of X with

parameters n and p

carrierCORRECT ANSWER: A person who has one recessive allele for a trait, but does not express the trait.

cell cycleCORRECT ANSWER: The regular sequence of growth and division that cells undergo to produce two new daughter cells

central dogmaCORRECT ANSWER: theory that states that, in cells, information only flows from DNA to RNA to proteins

Chargaff's RuleCORRECT ANSWER: A=T and C=G

Charles Darwin (1809-1882)CORRECT ANSWER: English naturalist who postulated a

theory of evolution by natural selection.

chiasmataCORRECT ANSWER: X-shaped regions where crossing over occurred.

chromosomesCORRECT ANSWER: a threadlike structure of nucleic acids and protein

found in the nucleus of most living cells, carrying genetic information in the form of genes.

cladesCORRECT ANSWER: a group of organisms believed to have evolved from a

common ancestor, according to the principles of cladistics.

cladistic approachCORRECT ANSWER: a method for constructing a phylogenetic tree

that is based on identifying the unique traits of each monophyletic group.

cleavage furrowCORRECT ANSWER: the first sign of cytokinesis during cell division in an animal cell; a shallow groove in the cell surface near the old metaphase plate
