A geneticist collected data of a population of mice. Of the 50 mice, 12 were homozygous black (BB), 24 were heterozygous black (

Bb), and 14 were brown (bb).
What are the allele frequencies for the (B) and (b) alleles in this population?

A. B = 0.32; b = 0.68
B. B = 0.36; b = 0.64
C. B = 0.48; b = 0.52
D. B = 0.45; b = 0.55

Answer:

option C: B = 0.48; b = 0.52

Explanation:

Of the 50 mice, 12 were homozygous black (BB), 24 were heterozygous black (Bb), and 14 were brown (bb).

BB        Bb       bb    Total

12     +  24    +  14   =  50

the formular for alleleic frequency (p) is (BB+ Bb/2) / total,

q = (bb + Bb/2) / total

Allelic frequecy of B (p) is (12 + 24/2) /50 = 12 + 12 = 24/50 = 0.48

Allelic frequency of b (q) is (14 + 24/2) / 50= 14 + 12 = 26/50 = 0.52

check p + q = 1; 0.48 + 0.52 = 1

Why does water move along its concentration gradients?
Artemon [7]
There is an electrical gradient and there is a concentration gradient.

1.) Chemical gradient better known as concentration gradient is much more powerful and compelling than the electrical gradient.

2.) Water is a polar molecule, meaning one side it positively charged while the other is negatively charged. This polar charged molecule causes water to have a weaker electrical gradient, thus the water has to move on its concentration gradient.

In certain mice, long tails (T) are dominant over short tails (t). If 2 hybrid mice mate, what will the outcome be?
yuradex [85]

Answer:

3 long tails : 1 short tail

Explanation:

This question involves a single gene coding for tail length in mice. The allele for long tail (T) is dominant over the allele for short tail (t). This means that an heterozygous mice will possess the long tail length.

According to this question, in a cross between two hybrid or heterozygote mice i.e. Tt × Tt, the following gametes will be produced by each parent:

Tt - T and t

Using these gametes in a punnet square (see attached image), the following will be produced: TT, Tt, Tt and tt.

Offsprings with genotype TT, Tt and Tt will have a LONG TAIL while genotype  tt will have a SHORT TAIL. Hence, the phenotypic ratio will be 3 long tails : 1 short tail.
