Which of the following statements is likely true about this observation? Select all that apply. Select one or more: a. Crosses between different genetically distinct dog breeds result in an offspring population with a higher frequency of heterozygotes than predicted by 2pq. b. Re-established gene flow between pure-bred populations reintroduces non-deleterious alleles into the mutt population. c. Random mating in mutts decreases the likelihood that offspring from two mutts are carriers for recessive congenital conditions compared to offspring from crosses involving two purebred dogs of the same breed. d. Crosses between different genetically distinct dog breeds result in an offspring population that is in Hardy-Weinberg Equilibrium. e. The small founding population of many dog breeds is a likely reason for the unusually high frequency of deleterious alleles in dogs from pure-bred breeds. f. Deleterious recessive alleles are less likely to be passed to offspring of mutts.
