In a diploid species of plant, the genes for plant height and fruit shape are syntenic and separated by 18mu. Allele D produces tall plants and is dominant to d for short plants, and allele R produces round fruit and is dominant to r for oval fruit. a. Identify the gametes for a plant with the genotype DR/dr, label parental and recombinants and give the frequency of each gamete type.
b. Give the same information for a plant with genotype Dr/dR
