What is the result of a cross of a heterozygous curly winged fly to a straight-winged fly? (Include both genotype and phenotype with fractions of each)
Do I need to make a monohybrid cross or a dihybrid cross?
If only two alleles of one gene are involved, it would be monohybrid. Since curly-winged is heterozygous, curly would be dominant, Cs. Assuming straight-winged is homozygous, ss.
Take it from there.
