About 50%, if there are no other genes available.

How would the probability of a brown-coated offspring change if the brown coated parent had the gene BB?
In this case, it doesn't matter what the genotype of the other parent is since BB is homozygous dominant (assuming this is the only gene that affects coat colour of course). All of the BB parent's offspring will PHENOTYPICALLY be brown-coated. They may be heterozygous though (Bb) depending on genotype of the second parent. So the PHENOTYPIC probability of a brown coat is 100% The genotypic probability of a homozygous genotype depends on the second parent.
When you cross a homozygous brown horse with a heterozygous brown horse which will be the dominant trait?
a brown horse i just did this in school a few weeks ago
What phenotype is produced byBB?
The phenotype is the physical/observable trait of the animal - therefore the phenotype of this rabbit is black fur.The genotype, Bb, makes this rabbit heterozygous.
What are the characteristics of watermelon seeds?
Black and brown Oval or round Black and brown Oval or round Black and brown Oval or round
What is heterozygous?
Heterozygous refers to alleles that are not the same. For example, lets pretend that the gene for hair color is H for brown hair and h for blond hair. If someone was HH, they would be homozygous because the two alleles of the gene are the same. If a person was blond, their genes would have to be hh, which is homozygous recessive. Heterozygous is when the alleles are different, like so: Hh.

In rabbits B is an allele for black coat and b is an allele for brown coat so what the genotypes for a rabbit that is homozygous for black coat and another that is heterozygous for black coat?
Black coat homozygous: BB Black Coat heterozgous: Bb
Black mare really black her only foal you know of was a brown She is bred to a strawberry roan for this spring any chance of getting a blue roan?
If the stallion carries the a gene and is heterozygous for roan your chances of a true blue roan are 50% if your mare is Ee. If she is EE there is no chance of a chestnut coated foal so the color of the foal will be controlled by the genetics of the stallion at the agouti site...either brown, bay or black.
If Ted has blue eyes and Mary is heterozygous what is the chance that their offspring will have brown eyes?
Assuming that you mean heterozygous for blue/brown eyes, 50%.
Show the cross between 2 heterozygous dogs. black fur B is dominant to brown fur b?
BbxBb = 25% homozygous BB; 50 % heterozygous Bb, and 25% homozygous recessive bb.
In birds black feathers are dominant over brown feathers Two birds with black feathers were crossed They had an offspring with brown feathers How is this possible?
Both parents were heterozygous (Bb). The offspring would statistically be: BB, Bb, Bb, and bb. All but the bb offspring would be black and the bb would be brown.
An organism that has an allele for brown eyes and an allele for blue eyes you?
Heterozygous (got it from my 9th grade biology textbook)
A plant can have either brown B or red b leaves Brown is the dominant trait If a plant has genotype bb which best describes the plant?
heterzygous with brown leaves
When you cross a homozygous brown horse with a heterozygous brown horse which will be the dominant trait?

A homozygous dominant brown mouse is crossed with a heterozygous brown mouse (White is the recessive color)?
A pretty bow
Both parent organisms have brown fur Bb what is the probability that an offspring will have brown fur?
75%
There are 20 students in room 14 of the students have brown eyes and 12 have blonde hair If a student is chosen randomly what is the probability that he or she will have brown eyes and blond hair?
The probability that he or she will have brown eyes and blond hair is 21/50.
