The wild-type coat color, agouti (aa) is dominant to solid-colored fur (aa). however, a separate gene c, when present as the recessive homozygote (cc), negates any expression of pigment from the a gene and results in an albino mouse. therefore, the genotypes aacc, aacc, and aacc all produce the same albino phenotype. a cross between heterozygotes for both genes (aacc x aacc) would generate offspring with a phenotypic ratio of 9 agouti: 3 black: 4 albino. which type of gene interaction is this
a. complementary gene interaction. b. duplicate gene interaction. c. recessive epistasis.

The sketch shows a rynchosaur, an extinct animal that is known only from fossils. there has been much debate about the classification of these creatures. some scientists suggest that they belong with primitive amphibians, and some think they are related to snakes and lizards.the data equally support both cases. which statement best explains how to draw a cladogram that includes the rynchosaur? draw the cladogram for amphibians. draw the cladogram for reptiles. draw two cladograms, both showing the traits, and leave it as a hypothesis. draw two cladograms, both showing the traits, and have scientists vote
