Rabbit Color
A precise tool.
What is the Rabbit Color & How does it work?
Rabbits exhibit a variety of coat colors due to genetic factors. The most common color in rabbits is brown, followed by black and white. The inheritance of these colors can be explained using Mendelian genetics.
P times P rightarrow F_1
P = Parental generation, F_1 = First filial generation
The color of a rabbit is determined by the presence or absence of certain alleles. For example, the allele for brown fur (B) is dominant over the allele for white fur (b). If both parents are heterozygous (Bb), the offspring can have three possible genotypes: BB, Bb, and bb.

Frequently Asked Questions
What is the difference between dominant and recessive alleles in rabbits?
Dominant alleles (like B for brown) are expressed even if only one copy is present, while recessive alleles (like b for white) require two copies to be expressed.
How do I determine the genotype of a rabbit with brown fur?
A rabbit with brown fur can have either the homozygous dominant genotype (BB) or the heterozygous genotype (Bb).
What is the probability of two heterozygous rabbits (Bb x Bb) having offspring with white fur?
The probability is 25% for each offspring to have white fur, as there’s a 1 in 4 chance of inheriting two recessive alleles (bb).
Can two black rabbits produce a white rabbit offspring?
Yes, if both parents are heterozygous for the color gene (Bb), they can produce offspring with white fur.
How do I calculate the genotype of a rabbit given its phenotype?
To determine the genotype, consider the possible combinations of alleles that could result in the observed phenotype. For example, a brown rabbit could be either BB or Bb.
What is the Punnett square method used for in rabbit genetics?
The Punnett square is a tool used to predict the genotypes and phenotypes of offspring based on the genetic combinations of parents.
How does the inheritance of rabbit coat color follow Mendel’s laws?
Rabbit coat color follows Mendel’s law of segregation, where each parent contributes one allele to the offspring. The dominant brown allele (B) masks the recessive white allele (b).
