Answer:
66 P_ Q_: 9 P_ qq: 9 pp Q_: 16 pp qq
Explanation:
As the genes are 20 m.u apart, recombination frequency between P & Q genes will be 20% (As 1% recombination = 1 m.u).
Parental cross \rightarrow PP QQ x pp qq
Parental gametes \rightarrow PQ, pq
F1 \rightarrow Pp Qq
F1 gametes \rightarrow PQ (Frequency = 0.4), pq (Frequency = 0.4), Pq (Frequency = 0.1), pQ (Frequency = 0.1) (As non-recombinant gametes frequency will be 0.8 & recombinant gametes frequency will be 0.2)
See the attached table.
