A population of wild-flowers was scored for flower color. There were 342 blue (BB) plants, 1622 violet (BR) plants and 797 red (
BARSIC [14]

Answer:

Since the homozygous have 2 alleles and heterozygous have one of each. The allelic frequency of blue will be calculated as;

<u>Step 1 Freq B</u>

Freq B = <em>2×no of Blue+ No of purple/2× total number of plants </em>        

No of blue plants(BB)=<em>342</em>

No of violet plants(BR)=<em>1622</em>

No of red plants(RR)=<em>797</em>

Frequency of allele B=<em> 2×342+1622/5522 </em>      

Frequency of allele B=<em>0.4176</em>

<u>2. Freq red</u>

Since allelic freq should add up to 1. freq for Red will be

1-0.4176=0.5824

also using the same formula used for Blue gives the same answer.

3.Expected number for Blue, Red and Violet

a)Expected frequency=p2=0.4176² =0.1744

Expected Blue plants= 2761*0.1744=481.5184

b)Expected frequency=q2=0.5824²=0.3392

Expected Red plants=2761*0.3392=936.5312

c)Expected frequency=2pq = 2*0.4176*0.5824 = 0.4864

Expected plants=2761*0.4864= 1342.9504

In a Nucleotide, we find which other biomolecule(s) making up a piece of the nucleotide itself?
forsale [732]
If these are the choices: 
A. No other biomolecules are present 
<span>B. Protein </span>
<span>C. Lipid </span>
<span>D. Carbohydrate
</span>
My answer is D. Carbohydrate.

A nucleotide has three parts. These parts are 1) <span>nucleobase aka nitrogenous base, 2) a five-carbon sugar or pentose sugar (either ribose or 2-deoxyribose), and 3) one or more phosphate groups.

D. Carbohydrate is under the 2) pentose sugar part of the nucleotide.</span>
