In Europe, approximately 4% of people are red-haired, mostly due to a recessive mutation in the melanocortin 1 receptor (MC1R).

Wewaii [24]

Answer:

33%.

Explanation:

The 4% population is red-hair due to the recessive mutation in melanocortin 1 receptor (MC1R).

Since, the population is in Hardy-Weinberg equillibrium- laet the frequency of recessive allele with red - hair is 'q' and the frequency of dominant allele in the population is 'p'.

$q^{2} =4\%$

$q^{2} = 0.04$

q=0.2

According to hardy-weinberg equillibrium

(p+q)=1

p=1-q

p=1-0.2

p=0.8.

The total population with non red hair is calculated by

= $p^{2} +2pq$

= 0.64 + 0.32

= 0.96

The percentage of the population with non red headed carrier for MC1Rr is calculated by:

=0.32/0.96*100

=33%

Thus, the correct answer is (B).

The nursing student considers the differences between gram-negative and gram-positive bacteria. which are true statements regard

igomit [66]

A scientist named Hans Christian Gram made 2 kinds of bacteria that is based on their differences in the cell walls. The gram positive and the gram negative.There are differences on these 2. One of it is that Gram negative are more resistant with antibodies compared to the gram positive. Example of these would be pseudomonas aeruginosa while for the positive would be Staphylococcus. Another difference between the 2 would be for flagellar structure in gram negative have 4 rings while positive has only 2.
