1 An Autotetraploid Plant With Genotype B B B B Is Selfed A What Proportion Of Progeny Will Not Have The Parental Gen 1 (55.4 KiB) Viewed 157 times

1) An autotetraploid plant with genotype B/B/b/b is selfed. a) What proportion of progeny will not have the parental genotype? b) The dominant allele B leads to purple flowers, the recessive allele b gives white flowers. Assume there is a second gene on the same chromosome (gene D).D causes ovate leaves, and d leads to round leaves. Loci B and D are 30 m.u. apart. The autotetraploid plant is BD/BD/bd/bd. What proportion of the progeny resulting from a testcross with a diploid plant will have purple flowers and round leaves, if there are no crossovers in the region between the two genes in the autotetraploid plant? Explain your answer.
