Enter a number rounded to two decimal places.arrow_forwardplease help with chartarrow_forwardYou are studying three linked genes in snapdragons. The flower color locus is in the center. There are 12.7 cM between the flower color locus and the plant height locus. There are 8.8 cM between the flower color locus and the leaf type locus. The coefficient of coincidence is 0.8. Pure-breeding tall, red-flowered plants with fuzzy leaves were crossed to pure-breeding dwarf, blue-flowered plants with smooth leaves. The F1 were testcrossed. Calculate the proportion of the testcross progeny that are expected to have blue flowers and smooth leaves. Round properly to 4 decimal digits. Answerarrow_forward
