The possible genotypes of the parental generation are as follows :
- Male : Night Blindness
- Female : Normal
What is Genotype ?
Genotype is the collection of the the two alleles that makes up the gene inherited by an offspring from its parents.
Given that only one of the males of the first generation suffers from Night blindness, He inherited the Night blindness from the parental generation. therefore the male from the parental generation is a carrier of the Night blindness allele while the Female is not a carrier.
Hence we can conclude that The possible genotypes of the parental generation are Male : Night Blindness and Female : Normal.
