A New Kind of Tulip Is Produced That Develops Only

Multiple Choice

A new kind of tulip is produced that develops only purple or pink flowers. Assume that flower color is controlled by a single-gene locus and that the purple allele (C) is dominant to the pink allele (c) . A random sample of 1000 tulips from a large cultivated field yields 847 purple flowers and 153 pink flowers. Estimate the proportion of all purple flowering plants that are heterozygotes and homozygotes.

A) heterozygotes = 694, homozygotes = 153
B) heterozygotes = 565, homozygotes = 282
C) heterozygotes = 476, homozygotes = 372
D) heterozygotes = 424, homozygotes = 423
E) heterozygotes = 0, homozygotes = 847
