In certain rats black fur is dominant over white fur If two rats both heterozygous for fur color are mated their offspring would be expected to have?
There different genotypes and two different colors Black fur is dominant --> F White fur is recessive --> f The parents are bot Ff (heterozygotes, and because black fur is dominant they have a black fur). If they mate, you get parents: Ff x Ff Offspring: FF Ff Ff ff so 25% will be homozygous for Black fur 2x25=50% will be heterozygous, and have a Black fur and 25% wil be homozygous for White fur. Hence, of their offspring, 75% will have a black fur and 25% will have a white fur
A female quinea pig homozygous dominant for black fur color is mated with a male homozygous for white fur In a litter of eight offspring there would probably be?
To answer this, first determine the genotypes of the parents. The female is homozygous dominant, which means it carries two copies of the black allele (which we will designate B), so its genotype we can represent as BB. The male is homozygous for the recessive trait (white, designated as b), so its genotype can be represented as bb. So the cross looks like this: BB X bb Next, we must determine the types of gametes each parent can produce. In this case it's easy, because both are homozygous. The female can only produce B gametes, while the male can only produce b gametes. Since the offspring carry one allele from each parent, all of the offspring can have only one genotype: Bb. Since black (B) is the dominant allele, and every offspring carries the dominant allele, all eight of the offspring from this cross will be black.
What does a Punnett Square do for geneticists?
Punnett Squares are useful because they allow you to see the chance of what genes will be handed down to the offspring. They are a quick and easy way to determine the chance of a offspring having a certain characteristic
The offspring of two true-breeding plants is .?
The offspring of two true-breeding plants is also true-breeding, meaning they will consistently display the same traits as the parents. This is because true-breeding plants are homozygous for a particular trait, so when they are crossed, their offspring will also be homozygous for that trait.
What color will the baby rabbits be if mom black and dad white?
The baby rabbits will likely have a mix of black and white fur since the parents have different coat colors. The specific colors of the offspring may vary depending on the genetic contribution from each parent.

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 a homozygous black guinea pig is crossed with a white guinea pig what is the probability that an offspring will have black fur?
depends if the black fur gene is dominant.. if it is... then yu would cross BB with bb making all heterozygous genotypes(Bb) therefore, having all possible offspring with black fur so theres a 100% probability of offspring with black fur(:
What do you think the offspring of a black mouse and a white mouse will look like?
The appearance of the offspring of a black mouse and a white mouse depends on the genetics of the parents. If the black mouse is homozygous for black fur and the white mouse is homozygous for white fur, all offspring would likely be black. However, if the black mouse is heterozygous, the offspring could be a mix of black and white, or even gray if there is incomplete dominance. Ultimately, the specific traits will depend on the alleles inherited from each parent.
Show the cross between 2 heterozygous dogs. black fur B is dominant to brown fur b?
The Punnett square for crossing two heterozygous dogs (Bb x Bb) would result in a 25% chance of offspring with homozygous dominant black fur (BB), a 50% chance of offspring with heterozygous black fur (Bb), and a 25% chance of offspring with homozygous recessive brown fur (bb).
What color is a black cat?
True to their name, black cats are black.
If a black and brown rabbit mate out of 4 offspring how may would be dark brown?
If a black and brown rabbit mate, their offspring could potentially have a mix of black, brown, and dark brown fur. It is not possible to predict exactly how many offspring would be dark brown without knowing the genetics of the parents. Each offspring has a different combination of genes that determine its fur color.
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
What fraction of the progeny of the cross BbTt x BBtt will have black fur and long tails?
50% of the progeny will have black fur and long tails. This is because all of the offspring will inherit at least one dominant B allele for black fur, and 50% will inherit a dominant T allele for long tails.
What is the probability that one of the offspring mice will have black fur?
The answer depends on how big the litter is: as the litter size increases the probability of one black fur increases. But as it gets larger still, the probability falls because two or more black furs become more probable.
Does polar bear have black skin?
Yes, Polar Bears have black skin, but most people do not know this because they have colorless fur (not white...). You can see this is true by looking at the nose of a polar bear, where the fur is thinnest, and you will see that it is black.
What are mammalian characteristics?
Fur. Feed milk to offspring.
