What is the genotype of a homozygous black guinea pig?
BB
In Guinea pigs, the genotype (BB) is black, and the genotype (bb) is white color, and (Bb) is grey color, The gene (Bland bare sex-linked.
What is the genotype of a white guinea pig?
bb
If we see a white guinea pig, it’s genotype must be “bb”.
What is the probability of a hybrid offspring in the cross?
Reading Punnett Squares and Pedigree Charts
| A | B |
|---|---|
| What is the probability of a hybrid offspring from this cross?, | 50% – the Bb guinea pigs |
| What are the phenotypes of the parents in this cross?, | Bb is black and bb is white |
| What are the genotypes of the parents in this cross?, | BB and bb |
What is the phenotype of a guinea pig?
In guinea pigs, dominant allele “B” states for black fur, while the recessive allele “b” states for white fur. If an animal has genotype bb, it means that it has two alleles for white fur. Thus, the phenotype of the animal is white.
Is DD heterozygous or homozygous?
| Individual | Genotype | |
|---|---|---|
| Sam (father) | DD | homozygous dominant |
| Sally (mother) | dd | homozygous recessive |
| Susan (child) | Dd | heterozygous |
Is FF heterozygous or homozygous?
Mendelian Genetics
| Genotype | Phenotype | |
|---|---|---|
| F F | Homozygous dominant | No cystic fibrosis (Normal) |
| F f | Heterozygous | Carrier (has no symptoms but carries the recessive allele) |
| f f | Homozygous recessive | Cystic fibrosis (has symptoms) |
What is the probability that parents AaBb and AaBb will have offspring with genotype AaBb?
The correct answer: The probability of an aabb offspring when AaBb x AaBb parents are crossed is b. 1/16 .
What is the probability of a homozygous offspring?
100%
If two homozygous dominants are crossed, the probability that an offspring will be homozygous dominant is 100% or 1.00.
How many HH alleles does a baby guinea pig inherit from its mother?
two
Explanation: “The amount of alleles that a baby Guinea pig inherit from the mother are two , 1 from its mother and 1 from its father.
What is example of phenotype?
Examples of phenotypes include height, wing length, and hair color. Phenotypes also include observable characteristics that can be measured in the laboratory, such as levels of hormones or blood cells.
Is PP purple or white?
The two alleles representing the trait are identical (e.g. PP for purple color, pp for white color). The two alleles representing the trait are different (e.g. Pp for purple color).
What happens if a guinea pig is crossed with a BB?
If a homozygous black guinea pig BB is crossed with a homozygous white guinea pig bb what is the probability that an offspring will have black fur? Wiki User ∙ 2011-11-17 01:30:08
What is the genotype of a black guinea pig?
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? Assuming black allele exhibits complete dominance and the white allele is recessive, the genotype is Bb. What is the probability of two black guinea pigs having black offspring?
How many guinea pigs are born with black fur?
If Bb also gives the guinea pigs black fur then 3 in 4 or 75% of them will be black. If only BB does then only 1 in 4 or 25% will be born with black fur. 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?
When does a guinea pig have a homozygous parent?
This depends on what punnet square b looks like. A guinea pig is homozygous if its two alleles are both dominant or both recessive. Usually, the homozygous parent is the one with either the two capital letters in the genotype or the two lowercase letters. Heterozygous is when there is one uppercase letter and one lowercase letter in the genotype.
