The clamshell orchid can have a dorsal sepal that is either bright purple (P) or yellow (Y), and may have ventral sepals that are curly (C) or flat (F). Assume that each trait is caused by a single gene in which one allele is completely dominant to the other and that these genes are independently assorting. Look at the table 1 below and determine the dominant and recessive alleles for sepal colour and shape. Table 1: resulting offspring produced by mating parents of the indicated phenotypes Cross 1 Cross 2 Cross 3 Parent 1 Purple, curly Purple, flat Purple, curly Parent 2 Yellow, flat Offspring Phenotypes Purple, curly 11 Purple, flat 20 Yellow, flat 0 Purple, flat Yellow, curly 12 Which shape phenotype is recessive? 9 59 43 X 7 0 Yellow, flat 11 Based on the information shown in the table above, determine the dominant and recessive alleles for colour and shape. Complete the information asked below: Which colour phenotype is recessive? 22 0 Choose appropriate symbols (basic nomenclature, single letter) for the colour alleles (dominant symbol in first blank, recessive in second): Choose appropriate symbols for the shape alleles (dominant symbol in first blank, recessive in second): Based on Table 1, determine the genotypes for the parents of Cross 1 and enter them below (colour first and shape second). Be sure to use appropriate genotype punctuation and don't put any spaces! Parent 1 (purple curly, first blank) x Parent 2 (yellow flat, second blank)
