We can expect 9 out of 16 offspring to be red, 3 out of 16 to be pink, and 3 out of 16 to be white.
Crossing a red flower (AaBb) with a pink flower (AaBb) will result in the following expected phenotypic ratios of offspring:
Genotype Ratio:
AABB: 1/16 (Red)
AaBB: 2/16 (Red)
AABb: 2/16 (Red)
AaBb: 4/16 (Pink)
aaBB: 2/16 (White)
aaBb: 4/16 (Pink)
aabb: 1/16 (White)
Phenotype Ratio:
Red: 9/16 (AABB, AaBB, AABb)
Pink: 3/16 (AaBb)
White: 3/16 (aaBB, aabb)
This is found according to the principles of Mendelian inheritance and Punnett squares. Each parent contributes one allele for each gene (A or a for gene A, B or b for gene B), and the offspring's genotype is determined by the random combination of these alleles. The phenotype, which is the observable characteristic, is then determined by the genotype and its interaction with the environment.
