A common recessive trait in dogs is deafness. A pure bred dog with normal hearing is bred with a pure line of deaf dogs. What percent of the F1 generation is expected to have normal hearing? O 25 % O 0% 50 % O 100 %

Color blindness is typically an inherited genetic condition in which individuals have a decreased ability to see color or differences in color. Color blindness only occurs in individuals who have two recessive alleles for the condition. Normal color vision is due to a dominant allele (C) Color blindness is due to the recessive allele (c) a) If Susan is homozygous for normal vision, and Matt is homozygous for color blindness, what is the likelihood (in percentage) that their son Alex will have color blindness? Perform a Punnett Square (either below or by hand on paper) to find the probability. Provide your answer in a full sentence. If you did the Punnett Square by hand, attach your photo to the next question.

Although in reality the inheritance of cleft chin (e.g., the deep chin dimple seen in Ben Ameck) is slightly more complicated, for now let's assume that the presence or absence of a cleft chin is determined by one gene. By studying pedigrees, we know that no child possesses a cleft chin unless at least one parent does (either the mom or the dad). Hint: Based on that last statement, you should now know the mode of inheritance! What is it? (Remember Recessive traits can hide, but dominant traits never do! ) O Cleft chin is a dominant trait. O Cleft chin is a recessive trait.

You are excited to be entering the world of chinchilla breeding!   At the most recent chinchilla pet event you purchased a lovely grey chinchilla with large ears. You do some research and learn that Grey is dominant to white (Gg), and large ears are dominant to small (Ee). Your chinchilla breeding mentor has many combinations of chinchillas and he gives you a one-time offer to breed with any of this chinchilla!    List all of the possible genotypes for your chinchilla:                           How could you determine which of these is the genotype of your chinchilla? How do we call this type of mating?
