The most accurate description of an organism with genotype AaBb is heterozygous. A homozygous genotype is aaBB and AA.
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.
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
In a BB x bb cross, all offspring will have the genotype Bb. The offspring will exhibit the dominant trait of the B allele.
A genotype is the actual genetic coding for an organism A phenotype is the physical appearance For example, let's say BB or Bb is the coding for black hair. BB/Bb is the genotype, and the black hair is the phenotype
Homozygous recessive.
"BB" and "bb" are Homozygous"Br" are hetrozygous
the genotype is BB
A. homozygous at two loci (AA & cc).
Heterozygous, because it has one dominant allele (B) and one recessive allele (b). An organism with two identical alleles (such as BB or bb) would be homozygous.
Genotype
Genotype versus Phenotype Genotype is your specific gene for a certain Trait. lets say B was for Tall gene and b is for small gene. your Genotype to Tall could be BB or Bb your gentype for small will be bb. Phenotype is what is the physical Appearance evne though the Genotpe has one gene that codes for big and one that codes for small for example (Bb) the physical appearnce is Tall.
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.
If both parents are genotype BB, the child can only be blood type B. The child's genotype would also be BB.
