White fur color is recessive and brown is dominant. The white mouse has a genotype of bb and the brown mouse has a genotype of BB. All offspring would be heterozygous with a genotype of BB and brown fur.
The gene for white mice is recessive. If a brown mouse carrying only brown genes mates with a white mouse the offspring will be brown but will carry a white gene. That means when a white mouse is mated to a brown mouse carrying a white gene the mouse could be white or brown.
If a brown mouse carrying a white gene and a brown gene was mated to another brown mouse that also had a white gene (because it was born from the union of a white mouse and a brown mouse) it could produce either a brown mouse or a white mouse.
2 white mice can only produce a white mouse unless a spontaneous mutation occurs (which is rare but possible)
The possible gene combinations from 2 mice carrying both white and brown genes would be :-
brown gene + brown gene= brown mouse or
white gene + brown gene = brown mouse or
white gene + white gene = white mouse
homozygous recessive
Homozygous recessive
The Aberdeen Angus produces both black and brown (red) calves.Selective breeding from the brown variety produces a greater preponderence of brown (red) offspring, known as the Red Angus.The Angus breed was first established in Angus, near Aberdeen, Scotland, UK.For more information, see Related links below this box.
It might be 2 dark brown rabbits
o
Probably balck. that or brown. i don't think white because that never happens.
they would come out with bits of the parents colours They would probably be majority of brown babies possible with white patterns. It depends if either rabbit is of solid colour.
his offspring hair color will be brown
Then the parents carried the gene for green eyes as a recessive gene.
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.
yeah in the granfarter has blue eyes which happened to me!
This is probably the result of the brown genes being dominant and the white genes being recessive. this is correct.
all brown the chances of brown eyes both parents have to have blueeyes for blue eyes to become dominant but its still possible no matter what for blue or brown
GeneticsYes, it's possible for a pair of blue-eyed parents to have a brown-eyed offspring. It all depends on each parent's genotype, and which trait comes from the dominant or recessive allele.
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
Genotype is the coded for traitPhenotype is the visible characteristicSo in the case where both parents had heterozygous dominant Brown eyes (Bb - big B for brown, dominant gene; little b for blue recessive gene); it is possible for the child to have blue eyes, by being homozygous recessive (bb).However this is an educated guess, as your question does not make sense.

Probably brown. It depends on what the parents carry as a recessive gene.
