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.

Answer:
When starfish were removed from their environment, the species richness of that area went down. This was because the starfish ate the mussels, and when the starfish were removed, the mussels became abundant and preyed on many of the other species.
This experiment showed that the starfish were a keystone species. A keystone species is a species that has a low biomass but a large impact on the community they are living in.
