What occurred during the Cambrian explosion? How is this significant in terms of common ancestry?
tia_tia [17]
The Cambrian Period marks an important point in the history of life on Earth; it is the time when most of the major groups of animals first appear in the fossil record. This event is sometimes called the "Cambrian Explosion," because of the relatively short time over which this diversity of forms appears

In guinea pigs hair straightness or curliness is thought to be governed by a single pair of alleles showing incomplete dominance
Nimfa-mama [501]

Answer:

Frequency of allele S is p = 0.4939

Frequency of allele C is q = 0.666

The population is not in Hardy-Weinberg equilibrium

Explanation:

Given -

Number of individuals with straight hair = 244

Number of individuals with curly hair = 444

Number of individuals with Wavy hair = 312

Let "p" represents the frequency for allele for straight hair and "q" represents the frequency for allele for curly hair

p^2 represents the frequency of genotype "SS"

p^{2} = \frac{244}{1000} \\= 0.244

q^2 represents the frequency of genotype "CC"

p^{2} = \frac{444}{1000} \\= 0.444

2pq represents the frequency of genotype "SC"

2pq = \frac{312}{1000} \\= 0.312

Frequency of allele S is p

= \sqrt{0.244} \\= 0.4939

Frequency of allele C is q

tex]= \sqrt{0.444} \\= 0.666[/tex]

For being in Hardy Weinberg's equation-

p+q=1\\

Substituting the values in above equation, we get -

0.4939+0.666\neq 1

hence, the population is not in Hardy-Weinberg equilibrium
