In Section B.2, by mating a heterozygous individual (Pp) with a homozygous recessive individual (pp), we observed progeny exhibiting both heterozygous (Pp) and homozygous recessive (pp) genotypes.
How to check the phenotype
This affirms that the unidentified organism may possess the heterozygous (Pp) or homozygous recessive (pp) condition.
C.1, as the dominant allele (P) responsible for purple flowers exists in the heterozygous state (Pp), all the offspring will manifest the dominant trait of purple flowers.
C.2, the progeny have an equal probability (50%) of showcasing the dominant trait of purple flowers (if they inherit the P allele) and an equal chance (50%) of displaying the recessive trait of white flowers (if they inherit the recessive allele, pp). This illustrates the fundamental principle of dominant and recessive traits in genetic inheritance.
