2. (2 pts) According to the cladogram, which organisms develop in an “amniotic egg”?

IrinaK [193]

Answer:

The answer is primates, rodents/rabbits, crocodiles and birds.

Explanation:

Cladogram

A cladogram is a diagrammatic epresentation of the evolutionary relationships between organisms that emerged from the same ancestor. Basically, it shows how closely one organism is related to another.

A cladogram differs with a phylogenetic tree in the sense that a cladogram only shows evolutionary relationships between one ancestor and all its descendants. On the other hand, a phylogenetic tree explains relationships between many clades (group of related species)

A cladogram also identifies various evolutionary points or milestones of the development of certain characteristics.

According to this cladogram, the amniotic egg evolved before the emergence of the common ancestor of primates, rodents, crocodiles and birds.

The presence of freckles is due to a dominant allele. four percent of the individuals in a particular population lack freckles.

vaieri [72.5K]

Let us assign the recessive allele for freckle to be f and the dominant F. According to the statement, we deduce that ff = 0.04.

The frequency of the recessive f allele is, therefore, is 0.2 (square root of 0.04 ).

Hardy-Weinburg p + q = 1

P + 0.2 = 1; p = 1- 0.2 = 0.8

Therefore using the Hardy-Weinburg equation of a population in equilibrium

P2+2pq+q2=1

Heterozygous individuals are;

2pq = 2*0.8*0.2 = 0.32

This is 32% of the population
