Answer:

Explanation:
It is given that
B is the dominant allele which represents the black color
and b is the recessive allele which represents the white fur.
B being dominant will result into black color fur for genotype "Bb"
Given -
Frequency of black fur allele (p) is 
As per Hardy Weinberg's first law of equilibrium

Substituting the value of p in above equation, we get -

q represents the frequency for white fur allele
Frequency of white fur phenotype is

Frequency of homozygous black fur phenotype (BB) is

As per Hardy Weinberg's second law of equilibrium -

Combined frequency of homozygous and heterozygous black fur phenotype is

Answer:
The correct answer is D is synthesized as a series of okazaki fragments.
Explanation:
During DNA replication the leading strand is replicated continuously whereas the lagging strand is replicated discontinuously.
As a result a continuous stretch of nucleotides are synthesized in the leading strand whereas a number of short fragments are generated in the lagging strand .These short fragments are termed as okazaki fragments.
