Question 1.
Given the following test cross data of tomato in which the heterozygous F1 plants were crossed with a strain that has ovate fruit, curled leaves and mottled coloration (homozygous recessive ovov cucu momo) and the following progeny were observed:

Normal   curled   mottled   3
Normal   curled     solid   26
Normal   flat         solid   304
Normal   flat        mottled 68
Ovate     curled    mottled 310
Ovate     curled       solid 60
Ovate        flat         mottled 24
Ovate          flat         solid 5

Note: Normal fruit vs. ovate fruit
Flat leaves or curled leaves
Solid color or mottled coloration

1. Determine the two parental genotypes.

2. Designate the parental, single crossover, and double crossover classes of offspring. Label each row of the above table: as parental, single crossover or double crossover class of offspring.

3. Determine the order of gene loci and calculate the genetic distance of these three loci. Present the data as a labelled linkage map.
