A. homozygous at two loci (AA & cc).
Genotype refers to an organism's complete set of genetic material inherited from its parents. Terms that describe genotype include genetic makeup, genetic code, and DNA sequence.
The "B" allele codes for a black coat color, so offspring with a BB or Bb genotype will both have a black coat due to the dominant nature of the "B" allele. The presence of at least one "B" allele ensures that the offspring will express the black coat color phenotype.
No probability. Neither parent has an "A" for the child to inherit to make an "AB".
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.
The most accurate description of an organism with genotype AaBb is heterozygous. A homozygous genotype is aaBB and AA.
the genotype is BB
A. homozygous at two loci (AA & cc).
Genotype
In genetics, BB represents a homozygous dominant genotype, where both alleles are dominant. Bb represents a heterozygous genotype, where one allele is dominant and one is recessive. bb represents a homozygous recessive genotype, where both alleles are recessive.
The mother is genotype AB, the father is either genotype BO or BB. If the father is genotype BO, the children can be genotype AB, AO, BB, or BO. This results in children with phenotype blood types of: AB, A, or B. If the father is genotype BB, the children can be genotype AB, AB, BB, or BB. This results in children with phenotype blood types of: AB or B.
The mother is genotype AB, the father is either genotype BO or BB. If the father is genotype BO, the children can be genotype AB, AO, BB, or BO. This results in children with phenotype blood types of: AB, A, or B. If the father is genotype BB, the children can be genotype AB, AB, BB, or BB. This results in children with phenotype blood types of: AB or B.

This results in children with phenotype blood types of: AB, A, or B. If the father is genotype BB, the children can be genotype AB, AB, BB, or BB. This results in children with phenotype blood types of: AB or B.
If both parents are genotype BB, the child can only be blood type B. The child's genotype would also be BB.
In the cross BB x bb, all offspring in the F1 generation will have the genotype Bb, as they inherit one allele from each parent. None of the offspring will have the same genotype as either parent.
Heterozygous
This question is worded weird, because if someone had a dominant phenotype, as in Brown eyes dominant, than they would be BB or Bb. The exact genotype would need to have a key to what one of their parents' genotype was. Example: If a man with brown eyes (dominant) had a mom with blue eyes (recessive) then what would the man's genotype be? the answer would be Bb because that means that the man's dad would have BB and mom would be bb and when using punnent square, his genotype is Bb (only possible genotype is Bb)
