In parrots blunt beak is dominant over pointy beak A heteroz

In parrots, blunt beak is dominant over pointy beak. A heterozygous male parrot with a blunt beak is cross with a female pointy beak parrot. Of the resultant offspring, 50% of the males have blunt beaks and 50% of the females have blunt beaks. What is the mode of inheritance?

1) Spontaneous mutation

2) Sex-linked

3) Autosomal recessive

4) Linkage

5) X-linked

Solution

The resultant offspring in parrots which have 50% blunt beaks in males and 50% blunt beaks in females is through the LINKAGE mode of inheritance. Because linkage mode of inheritance is of 50% -50% from parents.Hence linkage mode of inheritance is the best answer.
