How can you tell whether a black guinea pig is homozygous or heterzygous when black fur is dominant over white fur?
You could try breeding it with a homozygous recessive partner (hh)
Lets assume that you breed the original mystery rabbit with an hh recessive partner, and they have 10 offspring.
If the original rabbit is homozygous dominant, it would be HH + hh, which would give all 10 the offspring Hh genotypes, which would give them the dominant hair color.
If it was heterozygous dominant, it would be Hh + hh, which would lead to either Hh or hh offspring. This means that in theory, 5 would be dominant colored while the other 5 would not be.
What else can I help you with?
How could a guinea pig breeder whether a rough-coated guinea pig is homozygous or heteorzygous for this trait?
A breeder could determine if a rough-coated guinea pig is homozygous or heterozygous by conducting a test mating. Breeding the rough-coated guinea pig with a smooth-coated guinea pig would show if the rough coat is dominant or recessive. If all the offspring have rough coats, it indicates the rough-coated guinea pig is homozygous for the trait. If both rough and smooth-coated offspring are produced, then the rough-coated guinea pig is heterozygous.
What Guinea pig coat color is determined by a single gene. The allele for black coat color is dominant to brown. In a cross between two black-haired guinea pigs 20 offspring are born. If both parents?
If both parents are black-haired guinea pigs and the black coat color is dominant, they could either be homozygous (BB) or heterozygous (Bb) for the black coat gene. If both are heterozygous (Bb), the offspring ratio would typically be 25% homozygous black (BB), 50% heterozygous black (Bb), and 25% brown (bb). Therefore, among the 20 offspring, we would expect around 15 to be black (BB or Bb) and about 5 to be brown (bb) if the parents are Bb. If both parents are homozygous (BB), all offspring would be black.
If a homozygous black guinea pig is it dominant to white hair what is the phenotype?
The phenotype of the homozygous black guinea pig would be black hair. Since black is dominant to white in guinea pigs, having two copies of the black allele (BB) would result in the guinea pig displaying the black hair phenotype.
If a homozygous black guinea pig is crossed with a homozygous white guinea pig what is the probability that an offspring will have black fur?
100% because BB is dominant over bb and all the crosses make Bb
A black guinea pig crossed with an albino guinea pig produces 12 black offspring When the albino was crossed with a second black one 7 blacks and 5 albinos resulted What is the best explanation?
No idea i am guessing it is kinda like people. if a black and a white cross it is a 50/50 chance the child will be black or white so its unpredictable it was a 50/50 chance the baby pigs would be blacks or albinos. hope this helps YOU ARE SO RACIST!!!!!

In guinea pigs black hair color is dominant B and white hair color is recessive b What hair color are the guinea pigs offspring?
To determine the hair color of the guinea pigs' offspring, we need to know the genotypes of the parents. If one parent is homozygous dominant (BB) and the other is homozygous recessive (bb), all offspring will be heterozygous (Bb) and will have black hair. If both parents are heterozygous (Bb), approximately 25% of the offspring are expected to be homozygous dominant (BB), 50% heterozygous (Bb), and 25% homozygous recessive (bb), resulting in a 75% chance of black hair and a 25% chance of white hair.
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).
In guinea pigs the allele for a rough coat r is dominant for the allele for a smooth coat r a heterozygous guinea pig and a homozygous recessive guinea pig are mated lists the distribution of geno?
When a heterozygous guinea pig (Rr) is mated with a homozygous recessive guinea pig (rr), the possible genotypes of their offspring are 50% Rr (heterozygous, rough coat) and 50% rr (homozygous recessive, smooth coat). This results in a genotype distribution of 1:1, with half of the offspring expected to have rough coats and the other half having smooth coats.
What if a homozygous black guinea pig BB is crossed with homozygous white pig b what is the probability that an offspring will have lack fur?
If a homozygous black guinea pig (BB) is crossed with a homozygous white guinea pig (bb), all offspring will inherit one black allele (B) from the black parent and one white allele (b) from the white parent, resulting in heterozygous offspring (Bb). Since black fur is dominant over white fur, all offspring will have black fur. Therefore, the probability of an offspring having black fur is 100%.
If Brown fur (B) is dominant to white fur (b) in guinea pigs. Which is the only phenotype that is incorrectly paired with its possible genotype?
The phenotype "brown fur" can be associated with two possible genotypes: homozygous dominant (BB) and heterozygous (Bb). The phenotype "white fur," however, can only be paired with the homozygous recessive genotype (bb). Therefore, any pairing that suggests a genotype of BB or Bb with white fur would be incorrectly matched.
What Guinea pig coat color is determined by a single gene. The allele for black coat color is dominant to brown. In a cross between two black-haired guinea pigs 20 offspring are born. If both parents?

If both are heterozygous (Bb), the offspring ratio would typically be 25% homozygous black (BB), 50% heterozygous black (Bb), and 25% brown (bb). Therefore, among the 20 offspring, we would expect around 15 to be black (BB or Bb) and about 5 to be brown (bb) if the parents are Bb. If both parents are homozygous (BB), all offspring would be black.
What is the genotype of two black heterozygous guinea pig?
here is my answer found using a Punnett Square: for one trait (lets use hair color) both guinea pigs are hazel. But, because they are heterozygous they also have the resessive gene for white. So, you cross Hh with Hh. You then have this genotypic ratio: 1 HH:2 Hh:1 hh This can be translated into a phenotypic ratio: 3 hazel: 1 white The final answer: You will have 25% homozygous dominant, 50% heterozygous (showing the dominant), and 25% homozygous recessive.
Which guinea pig parents in punnett square b is homozygous and which are heterozygous?
The side because they are the same. The top because they are different.
If a homozygous black guinea pig is it dominant to white hair what is the phenotype?
The phenotype of the homozygous black guinea pig would be black hair. Since black is dominant to white in guinea pigs, having two copies of the black allele (BB) would result in the guinea pig displaying the black hair phenotype.
Paul decides to cross his long haired guinea pig with a short haired guinea pigBoth were homozygous for their traitWhat is the genotypic ratio of the offspring?
The offspring will look more like the mom but they will have mid hair.
If a homozygous black guinea pig is crossed with a homozygous white guinea pig what is the probability that an offspring will have black fur?
100% because BB is dominant over bb and all the crosses make Bb
