I think it’s all of the above.

Changing the environment would mean that traits are going to me favored, but that also means that niches also open up as a result.

I hope that helps.

Is erythematous a disease

Daniel [21]

Answer:

Erythema nodosum is characterized by tender, red bumps, usually found symmetrically on the shins. Up to 55 percent of cases have no clear identifiable cause. Sometimes, erythema nodosum is not a separate disease. Rather, it is a sign of some other infection, disease, or of a sensitivity to a drug.

Indicate the coat color and the proportion of offspring with that color for each of the following crosses of rabbits. Assume all

PolarNik [594]

Answer:

C) all chinchilla

Explanation:

As we know that dominance of alleles for the coat color in rabbits goes like this:

C+ > Cch > Ch > C.

The allele for full colour or agouti is designated as C+.
Allele for mutant coat color silvery- gray coat-chinchilla is Cch.
Allele for “Himalayan” coat is called ‘Ch
Albino rabbits have whole white coat and allele for this is c

If we cross homozygous chinchilla with homozygous chinchilla the cross will look like this:

P1: chinchilla x chinchilla

P1: Cch Cch X Cch Cch

F1: Cch Cch : Cch Cch

Since all offspring have Cch Cchgenotype that is foe chinchilla phenotype it means that all the offspring will have chinchilla phenotype that makes option C correct.

Hope it help
