In: Biology
Apterous is wingless . Wingless flies is a recessive trait and winged is the dominant trait .
Red eyes is similarly the dominant trait and sepia eyes is the recessive trait.
The dominant traits are exptessed in homozygous dominant and heterozygous conditions. That is WWRR or WwRr
In F1 generation all the genotypes are WwRr so genotypic ratio is 1.
All phenotype will be winged and ted colored eyes ,so again phenotypic ratio is 1.
If this helps please give it a positive rating thank you!
