Abiologist began studying a population of bullfrogs. in 1998, she found that
most of the male frogs croaked, but some did not. a bat species known to
prey on male frogs migrated to the area in 2005. the biologist returned to the area in 2008 and repeated population counts of male frogs. the table shows her data.

what factor most likely caused the noncroaking male population to increase
after 2004?

a) selective pressure in the form of a new predator

b) adaption of the croakers in the presence of a new predator

c) extinction of the croakers because of the new predator

d) learning to avoid the new predator

In a hypothetical breed of dogs, coat color is controlled by two genes. there are six different coat colors in this breed: black, brown, cream, gray, silver, and tan. consider the following crosses.cross 1: black females from a lineage of all black dogs are crossed with brown males from a lineage of all brown dogs. f1 males and females are all black. when f1 are intercrossed, f2 males and females are black or brown.cross 2: black females from a lineage of all black dogs are crossed with tan males from a lineage where all males are tan and all females are cream. f1 males are black, f1 females are gray. when f1 are intercrossed, f2 males and females are black, brown, gray, or tan.cross 3: silver females from a lineage where all females are silver and all males are gray are crossed with brown males from a lineage of all brown dogs. f1 males and females are all gray. when f1 are intercrossed, f2 males are black, brown, gray, or tan, f2 females are cream, gray, silver, or tan.select the correct statements regarding the mode of inheritance of the coat color genes.a) both genes are x-linked.b) both genes are autosomal.c) one of the genes modifies the expression of the other gene.d) each gene has an additive effect on the intensity of coat color.e) each gene independently specifies three colors.f) one of the genes is autosomal, and the other is x-linked.
