Question
In a diploid species of plant, the genes for plant height and fruit shape are syntenic and separated by 18 m.u. Allele D produces tall plants and is dominant to d for short plant, 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
**Please show work to help me figure out how to do these type of problems, I'm so lost.**
Explanation / Answer
(a) The correct answer is - Parental: 41% DR, 41%dr; recombinant: 9% Dr, 9%dR
because , 1 m.u. = 1% recombinance
•18 map units predicts
–18% recombinant gametes
•9 percent for each type
–82% nonrecombinant gametes
•41 percent for each type
that is why the answer is - Parental: 41% DR, 41% dr•Recombinant: 9% Dr, 9% dR
(b) The correct answer is - Parental: 41% Dr, 41%dR; recombinant: 9% DR, 9%dr
because ,
1 m.u. = 1% recombinance
•18 map units predicts
–18% recombinant gametes
•9 percent for each type
–82% nonrecombinant gametes
•41 percent for each type
that is why the answer is - Parental: 41% Dr, 41% dR•Recombinant: 9% DR, 9% dr
