A population of rabbits follows the typical pattern of inheritance and the law of dominance for fur color. B is the allele for b
lack fur and b is the allele for white fur. In a population of rabbits, 120 bunnies are born. How many bunnies should be black, according to the Punnett square? A) 60 B) 85 C) 90 D) 100
As per Mendel’s law of dominance, the dominant allele expressed in F1 offspring in heterozygous condition. Thus, in heterozygous condition, the dominant gene determines the phenotype for a trait. In the given question all the bunnies of the F1 generation will be black fur (Bb). B is the dominant allele. When heterozygous rabbit with black fur are crossed then both black and white fur rabbits are produced in the F2 generation in the ratio 3:1. Recessive phenotype, white fur (bb) will appear only in homozygous condition.
As per the question, 120 bunnies are born. 90 bunnies will be with black fur and 30 will be of white fur in the ratio 3:1. The 90 bunnies will be black.
Horses are diphyodontous, erupting a set of first deciduous teeth (also known as milk, temporary, or baby teeth) soon after birth, with these being replaced by permanent teeth by the age of approximately five years old.
