Contrivance - Answer an adaptation that is a result of the modification of a previous ancestor
Adaptation - Answer A trait that helps an organism survive and reproduce
Exaptation - Answer evolutionary adaptation of an existing structure for a completely new
purpose
Vestigial Trait - Answer A trait inherited from a common ancestor but is no longer used
dipliod cell - Answer cell that has 2 copies of each chromosome, one from egg, one from
sperm (46)
Hapliod - Answer having a single set of unpaired chromosomes, one egg (23) or on sperm (23)
Gametes - Answer reproductive cells
Crossover - Answer exchange of genetic material between non-sister chromatids
Meiosis - Answer cell division results in four daughter cells each with half the number of
chromosomes of the parent cell. (sexual reproduction)
Mitosis - Answer cell division in which the nucleus divides into nuclei containing the same
number of chromosomes
Nondisjunction - Answer failure of a pair of homologous chromosomes or sister chromatids to
separate normally during nuclear division
Trisomy - Answer an extra copy of a chromosome present in nuclei
, Law of Segregation - Answer alleles separate into gametes where each gamete contains one
allele of each gene
law of independent assortment - Answer pair of alleles that occur on different chromosomes,
will behave independently of each other
Recombination - Answer the genetic process by which one chromosome breaks off and
attaches to another chromosome during reproductive cell division
non-recombinant - Answer An offspring whose combination of traits has not changed from the
parental generation.
Cladistics - Answer comparing only recently derived traits to determine relatedness, rather
than all traits
allopatric speciation - Answer the process of speciation that occurs with geographic isolation
sympatric speciation - Answer The formation of new species due to preference
phylogentic species concept - Answer relatedness is determined by similarity in traits due to a
common ancestor
morphospecies concept - Answer determine species by physical similarities
plietropy - Answer single genes can affect multiple characteristics
Polygenetic - Answer two or more genes contribute to the phenotypic expression of a single
characteristic
epigenetic effects - Answer environmental influences on gene expression
sexual dimorphism - Answer Differences in physical characteristics between males and females
of the same species.
