Hi! Please complete a genetic cross of two parents BB x bb using a Punnett square Alleles B (dominant) has a fast phenotype and allele b (recessive) has a slow phenotype (B-fast, b-slow).

1. Show me the completed Punnett square with the genotypes and phenotypes in each square

2. Give the genotypic and phenotypic ratios

Which sentence best expresses the differing opinions of these two book reviews?
