Sauron [17]

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

nikitadnepr [17]

A white blood cell engulfing a bacterium is an example of blood functioning in protection.

<h3>What is a white blood cell?</h3>

White blood cells or better called leukocytes are blood cells produced in the bone marrow that belong to the immune system which are responsible for the <u>protection </u><u>and</u> <u>combat of infections and diseases</u>.

There are different types of white blood cells, among these are: <em>neutrophils, eosinophils, basophils, monocytes and lymphocytes</em>.

Usually the blood count of these leukocytes is used to detect situations such as infections, allergies, inflammation or leukemia.
