Question

In a certain species of animals, black fur (B) is
dominant over brown fur (b). Predict the genotypic
and phenotypic ratios of the offspring when both
parents are 'Bb' or have heterozygous black fur.​

Answer 1

$\huge{\boxed{\bf{\pink{An}\orange{swe}\pink{rs}}}}$

As the black fur is dominant over brown fur therefore the cross obtained as follows:

BBXbb On crossing the 2 the progency obtained are Bb which are the Black furred..

Answer 2

Answer:

The genotype of the offsprings will be: BB, Bb, Bb, bb

The phenotype of the offsprings will be:

Black fur : Brown fur in the ratio 3: 1  

Genotype is the genetic makeup of a cell and thus reflects the genome of the individual.

Phenotype is the morphological form or physical appearance of the individual. There is a specific genotype and phenotype which is attributed to a specific trait ( like brown fur in this question).

Since black fur B is dominant, so both parents with genotype Bb will be having black furs.
