BIO 320 - EXAM 2 QUESTIONS AND
ANSWERS 100% SOLVED.
allopatric speciation - ANSWERthe process of speciation that occurs with
geographically isolated, leading to reproductive isolation and genetic divergence
Aneuploidy - ANSWERA condition in which the number of chromosomes is not an exact
multiple of the haploid number, often leading to developmental issues.
Coevolution - ANSWERThe process where two or more species influence each other's
evolutionary trajectory, often seen in predator-prey relationships.
Fitness - ANSWERA measure of an organism's ability to survive and reproduce in its
environment, often quantified in terms of reproductive success.
Genetic Drift - ANSWERA mechanism of evolution that refers to random changes in
allele frequencies in a population, particularly significant in small populations.
Muller's Ratchet - ANSWERA concept in evolutionary biology that describes how
asexual populations accumulate deleterious mutations over time.
Maintenance of Genetic Variation - ANSWERGenetic variation is maintained through
mechanisms such as mutation, gene flow, and sexual reproduction, which introduce
new alleles into populations.
Process of Recombination - ANSWERDuring meiosis, homologous chromosomes
exchange genetic material at metaphase I, leading to the formation of recombinant
gametes.
Linked Genes and Recombination - ANSWERIf genes are linked, they tend to be
inherited together, reducing the likelihood of recombination between them.
Quantitative Trait Locus (QTL) Analyses - ANSWERQTL analyses help identify the
relationship between genetic markers and phenotypic traits, aiding in understanding
complex traits.
Heterozygosity and Polymorphic Loci - ANSWERHeterozygosity refers to the presence
of different alleles at a gene locus, while polymorphic loci are those that have multiple
alleles. Both measures indicate genetic diversity but differ in their focus.
Importance of Genetic Variation - ANSWERGenetic variation is crucial for a population's
adaptability to changing environments and is the raw material for natural selection.
