Hello please help.
1.In wild-type fruit flies, gray body G and regular wings R aredominant to black body g and vestigial wings r. A wild-type fruitfly homozygous for gray body and regular wings is crossed with ablack bodied vestigial winged fly.
a. If the resulting heterozygous offspring were crossed with aknown homozygous recessive individual and the two traits were notlinked, what would be the phenotypes and the frequencies of thiscross?
b. However, the above cross yielded the following phenotypes andfrequencies, independent of sex: 40% of the offspring weregray-regular, 40% of the offspring were black-vestigial, 10% of theoffspring were gray-vestigial, and 10% of the offspring wereblack-regular. What kind of inheritance is being demonstratedhere?
c. How many map units is body color from wing length?
d. If a third trait (eye color) is known to be 10 map units fromwing length and 10 map units from body color, show the sequence ofgenes on this chromosome.
