Bb is an example of an organism's ______. "Bb" is from Punnett square
Gene?
Bb is an example of what?
"Bb" is an example of an organism's genotype.
To understand how "Bb" represents an organism's genotype, we need a brief explanation of a Punnett square. A Punnett square is a tool used in genetics to predict the possible outcomes of a cross between two individuals. It allows us to determine the genetic possibilities for their offspring by combining the alleles (different forms of a gene) from each parent.
In a Punnett square, capital letters are used to represent dominant alleles, and lowercase letters are used to represent recessive alleles. In the case of "Bb," the letter "B" represents a dominant allele, while the letter "b" represents a recessive allele.
When it comes to genotypes, an organism has two alleles for a specific gene, one inherited from each parent. In this case, the organism possesses one dominant allele "B" and one recessive allele "b." Therefore, "Bb" represents a heterozygous genotype, indicating that the organism carries both the dominant and recessive alleles for that particular gene.
