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.

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).


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.

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.


A brown guinea pig(X)with smooth fur has parents that both have black coarse fur.X is crossed with a female guinea pig(Y)that is black with coarse fur.She is heterozygous for both characteristics.what is the symbol to indicate the cross between X and Y?

Cross between homozygous black rough (BBRR) guinea pig and homozgous white smooth guinea pig (bbrr) produced black and rough animals in F1​ generation.


Why is the genotype of the guinea pig with black fur expressed as (B)?

The genotype of the guinea pig with black fur is expressed as (B) because it represents the dominant allele for fur color. In genetic notation, uppercase letters indicate dominant traits, while lowercase letters represent recessive traits. Since black fur is a dominant characteristic, the presence of at least one (B) allele will result in the expression of that trait, regardless of the other allele's state. Thus, a guinea pig with the genotype (BB) or (Bb) will both display black fur.


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 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.


What is the genotype of the parent guinea pigs if they give birth to a brown guinea pig if the parents are white?

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%.
