g To generate a vaccine to pertussis toxin, a heat-killed preparation of Bordetella pertussis (the bacteria that produce pertussis toxin) is mixed with a purified preparation of the inactivated toxin protein. The mixture is then injected subcutaneously into mice. In an effort to enhance the antibody response to the toxin, a group of test mice is depleted of all their dendritic cells immediately prior to immunization. However, instead of enhancing the antibody response, the dendritic cell depletion nearly eliminated the anti-toxin antibody response because why

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?
