Question
In a diploid species of plant, the genes for height and fruit shape are linked and located 18 map units apart. Allele D produces tall plants and is dominant to the d allele which produces short plants. Allele R produces round fruit, which is dominant to allele r for oval fruit.
1) A plant with genotype DR/dr produces gametes. Identify the genotypes of the GAMETES this plant could produce, whether they are parentals or recombinants, and the frequency at which gamete type will be produced.
Gamete Genotype?(4) , Parental or Recombinant?(4) ,Frequency(4) ?
Explanation / Answer
Parental: 41% DR, 41% dr; recombinant: 9%Dr, 9% dR
