Answer:
The population is not following the Hardy-Weinberg equilibrium.
Explanation:
Hardy-Weinberg proposed that the population will remain in the equilibrium if they are not affected with the external natural force like genetic drift, mutation and many others. The gene pool of a population will remain in equilibrium state for generations.
The mathematical expression for the Hardy-Weinberg are
Genotypic frequency is p²+q²+2pq=1
Allele frequency is p+q=1
where p-dominant allele,
q-recessive allele
Therefore,calculating expected frequency of allele q,
q² (recessive genotype)- q²+2pq/1000
= 22+188/1000
=210/1000
= 0.21
q= 0.45
Calculating expected frequency of allele p,
Using p+q=1
p=1-q
p= 0.55 (expected)
Calculating observed value of frequency of p,
p²= p²+2pq/1000
= 790+188/1000
= 978/1000
= 0.978
p = 0.988 (observed)
Since the expected frequency does not match the observed frequency therefore the population is not under the Hardy-Weinberg equilibrium and the gene pool is disturbed.
Answer: It is a carbon residue left by a decaying organism.
This picture of the fossil is different from other fossils in terms of its impression. This is an example of compression fossil which is formed by the compression of something on it. The leaves of the tree got stuck on the rock and created an impression on it.
It is different from other fossils in the terms that it does not contains the actual part of the organism, it is just an impression.
