Hi,
Attached is solution diagram. You can see that true breeding means both have same alleles for purple PP and white WW flowers.
They were crossed to produce hybrid plants that all had purple flowers PW because purple was the dominant trait.
However, upon self fertilization of those hybrid plants, both purple and white flower plants were produced in 3:1.
Hope it helps!
Answer:
Genotype of long winged fly is Ll
Genotype of short winged fly is ll
Explanation:
Given
Allele for long wing trait is "L"
Allele for short wing trait is "l"
When a long winged fly is crossed with a short winged fly, half of the offspring have long wings and other half have short wings as the ratio is
Let us say that the genotype of long winged fly is Ll
and the genotype of short winged fly is ll
The cross between the two will produce following offspring
Ll * ll
Ll, Ll, ll, ll
Out of four off spring two have long wings (Ll)
and the other two have short wings (ll)
Thus the ration of long to short wing offspring is i.e
