The probable genotype for the white mouse would be homozygous recessive.
That depends which mouse has the dominate geans, they could potentially have either black or white offspring or even a combination of both.
Black female I = Bb
Black female II = BB
Brown male = bb
Depends. What letter are you using? Is white dominant over black?
BB and bb
A heterozygous genotype is always a capital letter, then a lowercase letter. Example: Hh
White fur
A dominant gene is always expressed if present, and the recessive gene is only expressed with the homozygous recessive genotype. For example, if the dominant gene is red (represented by the letter R) and the recessive gene is white (represented by the letter r), then a homozygous dominant organism's genotype will be RR, and its phenotype will be red. If the organism is homozygous recessive, then the genotype will be rr and the phenotype will be white. If the organism is heterozygous, then the genotype will be Rr, and the organism will be red.
To determine the genotype of a white ram, breed him with black females. Black females are homozygous recesive for the black trait, a. If the ram is homozygous dominant, all offspring will be white (and heterozygous). If the ram is heterozygous, approximately half of it's offspring will be white and half will be black.
The answer is genotype
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.
It would look like this. --¦ W W -------------- w¦ Ww Ww w¦ Ww Ww All the offspring would be black-furred, all carrying one dominant gene and one recessive.
The white eyed female fruit fly has two recessive traits for eye color. The genotype would be xx for example.
White-Ankled Mouse was created in 1904.
One way to determine the male's genotype would be to breed him to females with a known genotype of Black-Black. If any resultant calves were born with a white coat, you would then know that the male were Black-White. If calves were consistently black coated, you could be fairly certain he was also of the Black-Black genotype.

No.
Assuming black allele exhibits complete dominance and the white allele is recessive, the genotype is Bb.
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).
