It might be 2 dark brown rabbits
There are so many species of finch--and of many other members of the animal kingdom--because of something called natural selection. Natural selection comes about because of hereditary variations within a population, organisms producing more offspring than can survive, and because these offspring vary in their ability to in turn produce offspring and survive. For example, let's say there was a population of white-coated rabbits living in a woodland habitat. A particular mating between two white rabbits resulted in many white-coated offspring, but a few brown-coated offspring as well. (This is an example of hereditary variation.) Of all the offspring, many die because there are more than can survive, but those that die in greater numbers are white, not brown. This is because a white-coated rabbit is not suited to its habitat; its coat stands out to predators against the brown tones of the woodland. The brown rabbits, however, blend in (called camouflage) and so are not noticed as readily by predators. These rabbits will survive much better than their white siblings, and will go on to produce offspring of their own. Eventually, all or nearly all the white rabbits will be wiped out because their physical traits do not suit their habitat. All that will remain are the brown rabbits and their offspring. Each generation of brown rabbits will pass on their advantageous brown coats to the next... It's rather fascinating. To me, it's a miracle of nature that such hereditary variations occur at all. It's as though nature knows it needs to make changes in its populations and so it does!
There are four main colours of rabbits They Are: Brown Black White Grey

Both parents were heterozygous (Bb). The offspring would statistically be: BB, Bb, Bb, and bb. All but the bb offspring would be black and the bb would be brown.
75% or 3/4. The two F1 (offspring) mice have a genotype Bb, and express the dominant (brown) trait. When they mate, 1/4 will be BB (homozygous dominant - brown), 2/4 will be Bb (heterozygous - brown), and 1/4 will be bb (homozygous recessive - white).
Black coat homozygous: BB Black Coat heterozgous: Bb
It would depend on the brunette's genotype. If they are heterozygous for that trait, then the offspring could be any combination of blonde hair, brown hair, blue eyes, or brown eyes. If the brunette is homozygous dominant, then it's 100% sure the offspring will have a phenotype the same as the brunette.
Both of the parents were heterozygous with the blonde hair allele, which is recessive. When there are two parents that are heterozygous, there is a 25% chance their offspring will get two of the recessive alleles. A punnett square can be useful when determining the different phenotypes and genotypes possible in offspring
Sure you don't mean heterozygous dominant? If you don't there would be no blue eyed offspring. Let's assume you meant heterozygous dominant.B = brownbl = blueBbl X Bbl1/4 of the offspring would have blue eyes, 25%.

You can use a Punnet Square to figure it out. For example, if gray elephants dominate over brown elephants, and you cross 1 homozygous gray elephant (GG) and one homozygous brown elephant (gg), the Punnet square predicts that the offspring will all be heterozygous Gg. They will all be gray, however, because gray dominates over brown.
