Predict the genotypic ang phenotypic ratios in the offspring if the mother is bald and the father is not bald. perform a cross using a punnett square?

Assuming baldness is a trait determined by a dominant allele (B for bald, b for not bald), if the mother is bald (genotype BB or Bb) and the father is not bald (genotype bb), the offspring's genotypic ratio will depend on the mother's genotype. If the mother is BB, all offspring will be Bb (bald), resulting in a phenotypic ratio of 100% bald. If the mother is Bb, the genotypic ratio will be 1 Bb : 1 bb, leading to a phenotypic ratio of 50% bald and 50% not bald.
