If an organism has alleles Bb, it is considered heterozygous for that particular gene. This means it has two different alleles for that trait, one dominant (B) and one recessive (b). The dominant allele usually determines the organism's phenotype, while the recessive allele's effects may only be expressed if the organism is homozygous (bb).
What else can I help you with?
Are organisms with alleles BB recessive or dominant?
Organisms with alleles BB are considered homozygous dominant. This means that the dominant allele (B) is expressed in the phenotype. Dominant alleles mask the effects of recessive alleles in heterozygous individuals.
What does it mean if an organism is homozygous?
An organism is considered homozygous when it has two identical alleles for a specific gene, one inherited from each parent. This means that both alleles express the same trait, whether dominant or recessive. For example, if an organism has two alleles for blue eyes (bb), it is homozygous for that trait. In contrast, heterozygous organisms possess two different alleles for a gene.
What Describes an individual that has two alleles for a trait?
It sounds like you are referring to homozygous vs heterozygous. If an organism has two identical alleles of the same gene, it is said to be homozygous. If an organism has two different alleles of the same gene, it is said to be heterozygous.If a homozygous organism has two identical dominantalleles, it is said to be homozygous dominant, while an organism with two identical recessive alleles is said to be homozygous recessive.If this was not what you're asking, please clarify your question on the discussion page so someone can Terms_that_describe_two_alleles_of_the_same_genethis answer.
What does a punett square show?
The chance of a particular trait being inherited. For each trait there are several alleles, some are dominant and others recessive, for example brown eyes are dominant over blue. The recessive phenotype can only have a genotype with both recessive alleles eg. bb The dominant phenotype can have a genotype with both dominant alleles eg. BB or one of each eg. Bb A punnet square shows the likelihood of a phenotype being inherited from given genotypes, alleles etc... BB and Bb makes BB BB Bb Bb All offspring will have the dominant phenotype (BB or Bb) eg. brown eyes Bb and Bb makes BB Bb Bb bb One in four of the offspring will have the recessive phenotype (bb) eg. blue eyes
What genotype is produced by the phenotype B?
Genotypes are not created by phenotypes, they are the alleles/genes of the organism. Genotypes (in combination with environment) produce phenotypes. It would be expected that the genotypes Bb and BB would produce the phenotype B.
Are organisms with alleles BB recessive or dominant?
Organisms with alleles BB are considered homozygous dominant. This means that the dominant allele (B) is expressed in the phenotype. Dominant alleles mask the effects of recessive alleles in heterozygous individuals.
What describes an organism that has the genotypes Bb?
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.
If an organism has alleles BB?
The organism is homozygous dominant for that trait.
What is homozygous and heterozygous genotypes and the notation used to express them?
Homozygous or heterozygous are terms used to describe the genotype of a diploid organism at a locus of the DNA. Homozygous means that the organism has the same two alleles at that locus denoted by AA for dominant alleles or AA for recessive. Heterozygous means that the organism has two different alleles at that locus and is denoted Aa.
What word describes an organism that has the genotype Bb?
The most accurate description of an organism with genotype AaBb is heterozygous. A homozygous genotype is aaBB and AA.

Is the BB genotype heterozygous or homozygous?
Heterozygous
What genotype is produced by the phenotype B?
Genotypes are not created by phenotypes, they are the alleles/genes of the organism. Genotypes (in combination with environment) produce phenotypes. It would be expected that the genotypes Bb and BB would produce the phenotype B.
What is a heterozygote?
An organism that contains two different alleles of a particular gene and thus, providing an increase to varying offspring - diversification.In individual that contains two different alleles for a gene (it might be written Bb or Rr, etc.).
In genes what does BB Bb and bb mean?
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.
A hetrozygous genotype is when the alleles present are?
Different, such as Bb.
