Answer:
The correct answer is -
TT - short BB - blue eyes
Tt - short tail Bb - blue eyes
tt - no tail bb - brown eyes
Step-by-step explanation:
In this given question it is stated that short tails of ribbits are dominant over the no tail trait of the rabbits and similarly blue eyes trait of the rabbits is also dominant over the brown-eye trait.
A dominant trait is represented by a capital letter and a recessive trait is represented by the small letter so for the tails alleles will be denoted as T and t, and for the eyes, the alleles would be B for blue and b for brown.
The key for these traits would be-
TT - short BB - blue eyes, due to both dominant allele,
Tt - short tail Bb - blue eyes, due to dominant allele masks the recessive allele
tt - no tail bb - brown eyes, due to both alleles are recessive
