<span>If a population is not in Hardy-Weinberg equilibrium that can cause deviations from expectation depending on the assumptions of HW that are violated. If a population violates some of the assumptions (like mutations, migrations and selection) the allele frequencies will change over time. Also, if a non-random mating occurs (like inbreeding), it will cause an increase in homozygosity for all genes.</span>
It is known as stimulus or the plural form stimuli. It can be external or internal.
<span>It can eaither be PP or Pp.</span>
The offspring that will be produced in the cross would have tortoiseshell fur.
<h3>X-linked traits</h3>
In cats, the male is XY while the female is XX.
Assuming that black fur is caused by the allele B and the orange fur is caused by A
A black female will have the genotype 
An orange male will have the genotype 
Crossing the two: x
Offspring: 
, 
, , and
= tortoiseshell fur female
= tortoiseshell fur male

Answer:organisms that happen to share a common trait, even though they evolved
Explanation: polyphyletic groups have similar characteristics but
that have been grouped together
They do not share an immediate common ancestor.
