A population of mice has black or brown hair. The gene for black hair color (B) is dominant over brown (b). If 16% of the mice a
amm1812

B = 0.4

b = 0.6

Explanation:

From the question we derive that;

BB = 16%

Bb = 24%

The gene frequency for BB = 16/100 = 0.16

To find allelic frequency of B;

B = √0.16 = 0.4

Remember Hardy Weinberg rule that all allelic frequencies of a gene must sum up to 1;

p + q = 1

If p = 0.4

q = 1 – 0.4 = 0.6

b = 0.6

What is the mid-point of the segment (3, 7) and (2, -1)
pav-90 [236]

Answer:

(2.5, 3)

Explanation:

This question requires using the midpoint formula.

(formula is attached below as an image for better understanding)

First identify which values correspond with which variables in the formula:

First coordinate: (3, 7)

x_1 = 3

y_1 = 7

Second coordinate: (2, -1)

x_2 = 2

y_2 = -1

Now we plug the values into the formula and simplify:

((3+2)/2, (7-1)/2)

(5/2, 6/2)

(5/2, 3)

(2.5, 3
