Final answer:
The possible genotypes resulting from a cross between two individuals that are heterozygous (Bb) include BB, Bb, and bb, with expected phenotypic ratios of 3:1 for the dominant to recessive phenotype. The correct option is D) BB, Bb, and bb
Step-by-step explanation:
When two heterozygous individuals with genotype Bb are crossed, the possible genotypes of their offspring can be determined using a Punnett square. In such a cross, both parents can produce gametes with either the dominant allele B or the recessive allele b. When these gametes combine, the resulting genotypes can be BB, Bb, or bb. A typical Mendelian cross between Bb and Bb shows that there is a 25% chance for BB, a 25% chance for bb, and a 50% chance for Bb, resulting in an expected phenotypic ratio of approximately 3:1 for the dominant to recessive phenotype.
The correct answer to the question "Which of the following represents the possible genotype(s) resulting from a cross between two individuals that are heterozygous (Bb)?" would be D) BB, Bb, and bb. The correct option is D) BB, Bb, and bb
