Let us assign the dominant allele (that of brown hair) letter R
while
We assign the recessive
allele (that of white hair) letter r
We then note down the
Hardy-Weinburg equation p2 + 2pq + q2 = 1
Brown fur population (p2
+ 2pq) = 64% = 0.64
White fur population (q2) = 36% = 0.36
Then we also remember that the frequencies of both allele
add up to 1 (p + q = 1);
Therefore q = ü.36
= 0.6
P = 1 – q = 1 – 0.6 = 0.4
The heterozygous population will be 2*0.6*0.4 = 0.48 = 48%
Homozygous domain population will therefore be (64% - 48%) =
16%

Answer: There are three of chromosome number 18
Explanation: normally every chromosome is a pair, this is a triplet which is a genetic disorter
It contains the DNA and control the cell :)
The right answer is The oxygen component would have been smaller.
Photosynthesis is a biological process that occurs exclusively in plants with chloroplasts. It aims to synthesize oxygen from carbon dioxide and water.
If photosynthesis is absent, then the rate of oxygen in the air would be decreased since there is no production of the latter.
