Question
In gorgonzolas, there are three recessive traits that affect the organism's appeal: shrunken fruit, foul-smelling flowers, and short height. A heterozygote was crossed with a homozygote, yielding the following offspring: (46 foul-smelling),( 44 shrunken fruit, short height), (8 short height), (8 shrunken fruit), (7 foul-smelling, short height), (6 foul-smelling, shrunken fruit), (3 foul-smelling, shrunken fruit, short height), and (1 normal phenotype). What would the genetic map look like, and what are the map distances?Explanation / Answer
Let f = allele for foul-smelling flowers; s = allele for shrunken fruit; and h = allele for short height
The genetic map would be as follows:
-----f----------s-----h-----
Distance from f to s: 10 arbitrary units
Distance from s to h: 5 arbitrary units
Total length of segment: 20 arbitrary units
