Carrots have a gene called Fat-root with alleles F and f. F, which is dominant, encodes early development of the carrot root to make a bigger carrot faster, while f encodes later development. At an unlinked gene on the same chromosome, the dominant allele P makes purple carrots, while the absence of p makes orange roots. A true-breeding orange, skinny carrot is crossed to a true-breeding (meaning homozygous for all traits of interest) purple, fat carrot. The resulting F1 offspring are
a. true-breeding purple & fat
b. purple & fat, but heterozygous (not true-breeding)
c. 50% purple & skinny and 50% orange & fat
d. 25% of each parental and recombinant type
e. there is not enough information
