Kit⁺Kit⁺ Mice Were Crossed with Kit⁺Kit^t Mice

Kit⁺Kit⁺ mice were crossed with Kit⁺Kit^t mice. The embryos resulting from this cross were then injected with miRNAs specific to Kit mRNA. What phenotype will these embryos develop to have?

A) All mice will have the wild-type phenotype.
B) All mice will have the mutant phenotype.
C) The Kit⁺Kit⁺ mice will have the wild-type phenotype, and the Kit⁺Kit^t mice will have the mutant phenotype.
D) The Kit⁺Kit⁺ mice will have more mutant phenotypes than wild-type phenotypes, and the Kit⁺Kit^t mice will have the mutant phenotype.
E) The Kit⁺Kit⁺ mice will have the wild-type phenotype, and the Kit⁺Kit^t mice will have a 1:1 ratio of the wild-type to mutant phenotype.
