Question

determine the phenotypes of the offspring shown in the punnett square. bb: bb: bb: retry

Explanation:

Step1: Understand dominant - recessive concept

In genetics, if 'B' is the dominant allele and 'b' is the recessive allele, individuals with at least one dominant allele (BB or Bb) will show the dominant phenotype.

Step2: Determine phenotypes

For BB, since it has two dominant alleles, it shows the dominant phenotype. For Bb, having a dominant allele 'B', it also shows the dominant phenotype. For bb, with two recessive alleles, it shows the recessive phenotype.

Answer:

BB: Dominant phenotype
Bb: Dominant phenotype
bb: Recessive phenotype
