A female, tortoise-shell, tailless Manx cat mates with a male solid black tailless Manx cat. Their first litter produced 1 taill
ess tortoise-shell female, 1 tailless black female, 1 tailed black female, 1 tailless orange male, 1 tailless black male and 1 tailed orange male. In the second litter, they had 1 tailed tortoise-shell female, 2 tailless black females, 1 tailless black male, 1 tailless orange male, and 1 tailed black male. (Hint: Look at each trait separately for phenotypic ratios, Mendelian vs NonMendelian patterns) Required:
a. What are the inheritance patterns of the two genes described?
b. What are the genotypes of the parents?
It is possible to obseve that the fur color of the feline is connected with the male chromosome "X". The presence of Xb (recessive) and XB (dominant) results in the tortoise color.
The ausent tail T is carried in the autosomes with a dominacy over the presence of tail "t" and the presence of both dominances "TT" results in the death of the offspring.
In the experiment, the independent variable is the drug amount. Experiment group is given certain amount of drug, control group is not given the drug. The dependent variable is the body fat. I think you means the control is the living environment including food and water.
