Agouti cats (awa or awaw - we will not consider here the other alleles discussed in
Video 3.1) can have various tabby striping/spotting patterns depending on their
alleles of the T gene. Agouti cats (awa or awaw ) with the genotype TªTª or Tªt are
Abyssinians, and those with the genotype tt are blotched. However, these
striping/spotting patterns are not observed in non-agouti cats of aa genotype,
which are black regardless of their T alleles. This information is also presented
above in schematic form, and is background information for the next question as
well as this one.

Expert Solution
Step 1: Understanding the Allelic Relationships

In this scenario, we have two genes, A (Agouti) and T (Tabby), that determine coat color and pattern in cats.

  • A Gene (Agouti):
    • Genotype aa or awa results in non-agouti cats, which are black regardless of their T alleles.
  • T Gene (Tabby):
    • Genotypes TT or T't result in Abyssinian cats.
    • Genotype tt results in blotched tabby cats.
