b
many possible genotypes, producing many possible phenotypes
c

d
fewer phenotypes than most single gene traits

A polygenic trait can have many possible genotypes, producing many possible phenotypes

Explanation:

The polygenic trait is influenced by more than one gene leading to the possibility of many genotypes and phenotypes. This trait itself is a characteristic or a phenotype which is controlled or influenced by multiple genes.

The phenotypes are produced with addition of each dominant allele. Phenotypes like height, skin color of a person are controlled by many genes and the dominant alleles finally produce the respective phenotype.

These does not follow Mendel’s rule of inheritance, where one phenotype is controlled by one genotype.

i dont know this but ask your teacher for !
