In fruit flies, the traits for a yellow body and white eyes are always inherited together. which conclusion can be drawn from this phenomenon? a. the genes for the traits are adjacent in the genome. b. both traits are dominant. c. the species has only one allele for each trait. d. the traits are controlled by one gene.

What two fields of study provide the core information that is used to classify organisms?

Coat color in cats is determined by genes at several different loci. at one locus on the x chromosome, one allele (x ) encodes black fur and another allele (xo) encodes orange fur. females can be black (x x ), orange (xoxo), or a mixture of orange and black called tortoiseshell (x xo). males are either black (x y) or orange (xoy). bill has a female tortoiseshell cat named patches. one night, patches escapes from bill\'s house, spends the night out, and mates with a stray male. patches later gives birth to the following kittens: one orange male, one black male, two tortoiseshell females, and one orange female. what are the genotypes of patches, the stray male, and the kittens?
