how are genes expressed for a particular trait?

Genes are expressed in two ways which could be either genotype or phenotype

genotype reflects the dominancy or recessives of a particular trait over another while phenotype entails the physical expression of such trait which could be height, color of skin among others

e.g

If P is purple while p is white

PP x Pp= PP, Pp, PP. Pp these are the genotype produced from the crossing of two parents which results into 2 homozygous gene and 2 heterozygous gene without any recessive gene

while the phenotype shows that all the offspring are Purple
