From this we have that 25% of the progeny have the ‘SS’ genotype and are hence round (homozygous), 50% have the ‘Ss’ genotype and are also round (heterozygous), and 25% of the progeny have the ‘ss’ genotype and are hence wrinkled. Pulling like phenotypes together we have that 75% (25% + 50%) of the ...
