The results of pedigree analysis are less definitive than breeding experiments because the small size of human families causes Blank______.Multiple choice question.differences in chromosome segregation during meiosisfailure of independent assortmentlarge sampling errors

Genetic variation is accomplished by all but one of the following. Choose the EXCEPTION.the events of meiosis Icrossing overindependent assortmentthe events of meiosis II

The amount of genetic variation present in naturally occurring populations is Blank______.Multiple choice question.insignificantpractically nonexistentvery littlesignificant

The formation of fertile hybrids in artificial settings is not sufficient evidence to define a species because Blank______.Multiple choice question.it doesn't take into account the effects of gene flowonly a small percentage of individuals can hybridize in artificial settingsit may not occur in a natural setting

Fill in the Blank QuestionFill in the blank question.Independent assortment of alleles of different genes can be explained by the random alignment of of chromosomes during meiosis I.

Knowledge on populations requires understanding of the concept of the gene pool. The following are true regarding the relationship between populations and gene pools, EXCEPT:a.An individual can become part of the gene pool if that individual can share alleles with the other members of the population.b.The gene pool is simply the collective term referring to the entire genotypes entailed in a given population. c.Individuals who are not products or are not involved in the process of sexual reproduction are excluded from the gene pool. d.Small populations tend to interbreed and therefore decrease genetic variation, primarily because of the unshared gene pool.
