The answer to this question would be: a male inherits only one allele of the X-linked gene controlling hair color

Tortoiseshell phenotype appears when a cat has two different X-linked gene that controls hair color. This result as a combination of hair color. Male cat sex gene is XY. Normally male cat only has 1 X gene, thus only have 1 color and can't have tortoiseshell phenotype unless there is pathological multiplication in X gene.

Aneli [31]

There are choices for this question namely:

Ativan 1 mg orally
Nitroglycerin SL 
Serum electrolytes 
Chest x-ray

The correct answer is "Nitroglycerin SL". The SL means sublingually. The physician will still order Nitroglycerin to be taken sublingually whenever there is chest pain. The patient's medication may have been expired being stored for 12 months now. Ativan or Lorazepam will not be given as this is a sedative and there is no indication for sedatives.

Serum electrolytes and chest xray will not be requested as these diagnostic examinations are not usually done in patients with stable angina.

Reptile [31]

Answer:

a. Determine the allele frequencies of:

f(T) = 0.485 ≅ 0.48

f(t) = 0.515 ≅ 0.52

b. Determine the genotype frequencies of the exposed generation

F (TT) = 0.21
F (Tt) = 0.55
F (tt) = 0.24

the genotype frequencies of the next generation

F(TT) = 0.23
F(Tt) = 0.5
F(tt) = 0.27
