"C. They never have a shell" is the best statement that describes a characteristic of amoeboids. These can take multiple different shapes and forms and must be flexible.
The correct answer for the question that is being presented above is this one: "(3) all cells in his body." A man is exposed to large amounts of ultraviolet radiation while sunbathing on the beach. This exposure causes genetic change in the DNA of a skin cell. In the future, this change can be passed on to (3) all cells in his body.
Here are the following choices:
(1) his male and female children
(2) his male children, only
(3) all cells in his body
(4) his skin cells, only

Answer:
Frequency of B allele is 0.6681
Explanation:
If p represents the frequency of dominant allele and q represents the frequency of recessive allele, according to Hardy-Weinberg equilibrium:
p + q = 1
p² + 2pq + q² = 1
where p² = frequency of homozygous dominant genotype
q² = frequency of homozygous recessive genotype
2pq = frequency of heterozygous genotype
Given that number of recessive chestnut horse = 28
Total horses = 226 + 28 = 254
frequency of b² genotype = 28/254 = 0.1102
frequency of recessive b allele = √0.1102 = 0.3319
So, frequency of B allele =
1 - 0.3319 = 0.6681
Hence frequency of B allele is 0.6681
