Consider a locus with two alleles - B and b. B is dominant, while b is recessive. There is no mutation. B has a selective advant

Marat540 [252]

Answer:

0.09

Explanation:

<h3><u>Before selection</u></h3>

Total number in population = 1000

Genotype frequencies

Genotype frequency of BB = 500/1000 = 0.5

Genotype frequency of Bb = 250/1000 = 0.25

Genotype frequency of bb = 250/1000 = 0.25

Allele frequencies

Allele frequency of B = BB genotype frequency + half of the Bb genotype frequency = 0.5 + (0.25/2) = 0.625

Allele frequency of b = bb genotype frequency + half of the Bb genotype frequency = 0.25 + (0.25/2) = 0.375

<h3><u>After selection</u></h3>

We are told that after selection, the genotype frequency of bb is changed as they become 50% less fit. This means the frequency of bb individuals changes from 250 to 125 individuals (50% reduction).

Now the total number of individuals is 500 + 125 + 250 = 875.

Genotype frequencies

Genotype frequency of BB = 500/875 = 0.57

Genotype frequency of Bb = 250/875 = 0.29

Genotype frequency of bb = 125/875 = 0.14

Allele frequencies

Allele frequency of B = BB genotype frequency + half of the Bb genotype frequency = 0.57 + (0.29/2) = 0.715

Allele frequency of b = bb genotype frequency + half of the Bb genotype frequency = 0.14 + (0.29/2) = 0.285

<h3><u>Change in frequency of B after 1 generation</u></h3>

0.715 - 0.625 = 0.09

S. pyogenes is a gram-positive bacterium. gram-positive bacteria have structural differences that distinguish them from gram-neg

yKpoI14uk [10]

The method may be easily applied in order to obtain additional information for clinical prescriptions from. By new method, we could easily distinguish gram-positive and gram-negative bacteria in liquid culture media within 10 min. This modest and fast technique may be beneficial for determining the treatment course of patients with UTIs, particularly for those without a prior history of UTIs.

Anti-infectives are used to treat urinary tract infections which include which anatomical structures? (select all that apply.)

ivolga24 [154]

These anatomical structures are the following:
1. The urine itself which serves as an antiseptic, washing potentially harmful bacteria out from the body during normal urination
2. The ureters join into the bladder in a manner designed to prevent urine from backing up into the kidney when the bladder squeezes urine out through the urethra.
3. The prostate gland in men that secretes infection-fighting substance.
4. The immune system defenses and antibacterial substance in the mucous lining of the bladder eliminate many organisms.
5. The vagina of a healthy women, it is colonized by lactobacilli, a beneficial microorganisms that maintain a highly acidic environment (low pH) that is hostile to other bacteria. It also produces hydrogen peroxide, which help eliminate bacteria and reduces the ability of Escherichia coli (E. coli) to adhere to vaginal cells that is the major bacterial culprit in urinary tract infection.

Proof reading is performed by?

anygoal [31]

It's like editing over what's already written. it's the process of reading something and marking for any error. (: Usually deemed more helpful when you let two completely different people proof read the same paper to get a better result!
Good luck, rockstar! (: I wish you the best and hope you pass!
