In a hypothetical population of plants, flower color is determined by a single gene with two alleles. In a population of 500 pla
Dvinal [7]

Answer:

Phenotype genotype Number of individuals

Red RR 245

Pink Rr 210

White rr 45

Number of alleles in total

R = 245 + 245 + 210 = 700 ---> 700/1000= 0.7 R frequency

r = 210 + 45 + 45 = 300 -----> 300/1000 = 0.3 r frequency

Predict (Hardy Weinberg) genotype frequencies=

p^2 + 2pq + q^2 = 1

p= 0.7

q=0.3

0.49 + 0.42 + 0.9 =1

According Punnett Squares in F1 we have=

Rr* rr = Rr 50% and rr 50%

In a diploid species of plant, the genes for plant height and fruit shape are syntenic and separated by 18 m.u. Allele D produce
FinnZ [79.3K]

Answer:

C)Parental: 41% Dr, 41% dR; recombinant: 9% DR, 9% dr.

Explanation:

The notation Dr/dR for genotypes means that one homologous chromosome has the alleles Dr and the other homologous chromosome has the alleles dR.

The heterozygous plant  Dr/dR will produce 4 types of gametes: two identical to the chromosmes the individual has in its somatic cells (called parental), and two gametes which will be a mix of the alleles in the homologous chromosomes (called recombinant).

  • Dr: parental
  • dR: parental
  • DR: recombinant
  • dr: recombinant

To calculate the frequency of each type of gamete, we must use the formula:

Distance (map units) / 100 = frequency of recombination.

18 mu / 100 = 0.18.

The total frequency of recombination between the genes D and R is 0.18, but every time crossing over happens, two recombinant gametes are generated. Therefore, each recombinant gamete will have a frequency of 0.18/2=0.09 = 9%.

The frequency of parental gametes will be:

1 - frequency of recombinant gametes

1 - 0.18 = 0.82

But there are 2 parental gametes, so each of them will have a frequency of 0.82/2=0.41 = 41%.
