Two alleles determine flower color in the plant Datura:P determine purple and p white. The P locus is on the smallestchromosme, number 3. In plants trisomic for this chromosme, n + 1pollen is never functional. Assume that P is close to thecentromere (therefore no crossing-over). What is the expected ratioof purple: white in the offspring of the following crosses?
a) Ppp females * pp male
b) PPp female * PPp male
