Answer:
d) do all jobs for survival
Explanation:
A single cell perform all its activity on its own.
Because they are made mostly or partly out of gas.
In order for a recessive trait to be apparent in an organism, the organism must receive a copy of the allele for that trait from both parents.
Let the:
black coat: B
brown coat: b
Trotter: T
pacer: t
The offspring received both of the recessive alleles because it demonstrates the recessive phenotypes. Therefore, they genotype of the offspring is:
bbtt
The black horse that is a pacer that can produce this offspring will be:
Bbtt
Therefore, the brown horse's genotype must be:
bbTt
The offspring will receive b from both parents and t from both parents.
