How A Bb guinea pig crosses with a Bb guinea pig all four off springs re black how does this happen?
In guinea pigs, the black coat color is typically determined by the dominant allele (B), while the brown coat color is determined by the recessive allele (b). When two Bb guinea pigs are crossed, the possible genotypes of the offspring are BB, Bb, Bb, and bb, resulting in a 3:1 phenotypic ratio. However, if all four offspring are black, it suggests that the bb genotype did not occur, possibly due to a selection bias in the observed offspring or an error in the initial assumption about the parents' genotypes.

What would happen if a meteorite hit a black hole?
It would be torn apart by tidal forces as it approached the black hole. Once it crosses the event horizon id disappears into the black hole forever.
What is the phenotype of a black guinea pig and a white guinea pig?
A black guinea pig would have a black coat color, while a white guinea pig would have a white coat color. Color variation in guinea pigs is due to different alleles of the gene controlling coat color, resulting in different phenotypes.
Is it ok to wear black crosses?
Yes.
What animal is bad luck in Russia?

Do black cat mean good or bad luck?
The superstition is your in for bad luck if a black cat crosses your path.
What kind of cross might tell you if a black guinea pig is BB or Bb?
A test cross with a homozygous recessive guinea pig (bb) would reveal the genotype of the black guinea pig. If all offspring are black, then the black guinea pig is most likely homozygous dominant (BB). If both black and white offspring are produced, then the black guinea pig is likely heterozygous (Bb).
Is Sephy white in Noughts and Crosses?
No Sephy is black.
What does omen mean?

Should a guinea pigs poo be black?

What is the genotype of a black guinea pig if it is crossed with a whites guinea pig and they have 4 offspring that are black and 2 offspring are white?
The black guinea pig is likely heterozygous (Bb) for coat color, while the white guinea pig is homozygous recessive (bb). The black guinea pig passes on a black allele to all offspring, resulting in 4 black (Bb) and 2 white (bb) offspring.
Which direction does a black cat cross from right to left?
A black cat crosses from right to left.
