In dogs, the barking trait is dominant over the silent trait. Using Punnet Square, work out the possible puppies born to two barking parents with genotype (Rr).

Solution

As we can be inferred from the punnet square
Characteristics of puppies:
$3$ puppies will bark,
$1$ puppy will be silent
Genotypic ratio= $1 : 2 : 1 (R R : R r : r r)$
Phenotypic ratio= $3 : 1$ (Barking trait:Silent trait)
