Question

Problem 4: In guinea pigs, rough coat (R) is dominant over smooth coat (r). What is the result of a cross between two homzygous rough-coated guinea pig?

Answer 1

the genotypes of the parents are RR and RR

the gametes from the first parent are RR

and from the second parent RR

on the punnet square we can see that 100% of the offspring will be RR

`\left[\begin{array}{ccc}RR&RR\\RR&RR\end{array}\right]`
