For a gene that determines wing color in butterflies, there are three possible genotypes: BB (blue wings), bb (white wings), and

Bb (white wings with blue blotches). A sample of 100 butterflies was collected, and the following was observed:
Wing Color Number of Butterflies
blue 60
white with blue blotches 30
white 10


What is the frequency of the Bb genotype in this population if it is in Hardy-Weinberg Equilibrium?

Answer: The frequency of the b allele is calculated as follows: since there are 2 alleles in each organism, total number of genes is 200. The number of white alleles is 10*2+30 (since there are 2 copies of the alleles in white organisms and 1 copy of the b allele in the white wings with blue blotches). So the total number of white alleles is 20+30=50 white alleles. The frequency of the white allele is then 0.25. So the frequency of the blue allele is 1-0.25=0.75. Since heterozygous term is 2*p*q, the frequency of the Bb genotype is 2*0.25*0.75=0.375. Hope that helped!

Manny is using a computer model to investigate the effects of substitution mutations. The model presents Manny with a long base
Troyanec [42]

Answer:

The most likely explanation for the truncated polypeptide -due to the substitution of cytosine for adenine- is that mutation introduced a stop codon in the middle of the gene.

Explanation:

A codon consists of three nucleotides -in the RNA chain- whose order determines a specific amino acid. Not all codons code for amino acids, as there are termination codons, also called stop codons, which are UAG, UGA and UAA.

If in Manny's computer model, the substitution of cytosine by adenine produced a termination codon, the synthesis of a peptide is stopped prematurely resulting in a truncated peptide.

Two methods of testing that would be more accurate than litmus paper
Kay [80]

Answer:

pH meter and pH paper.

Explanation:

There are a few other ways that are commonly used, including titration, but most are tedious and require detailed hands-on work. A pH meter is normally assisted by the use of a computer or a digital user interface. The use of pH paper can be likened to the use of a Galileo thermometer.
