Transcribed Image Text:### Quiz Question on Gene Linkage and Gene Order
Please select the correct statement regarding the linkage and order of the genes based on gene linkage analysis:
1. ○ All three genes are linked, but need to do more crosses and data to determine the gene order.
2. ○ All three genes are linked with the flower color gene (F) in the middle.
3. ○ All three genes are linked with the seed weight gene (S) in the middle.
4. ○ All three genes are linked with the leaf size gene (L) in the middle.
![**Question 6**
A diploid plant has red flowers, heavy seeds, and large leaves. The plant is heterozygous for the following three genes:
- flower color (gene “F”),
- seed weight (gene “S”),
- and leaf size (gene “L”).
This plant is testcrossed to a plant, which has white flowers, light seeds, and small leaves. The progeny of the testcross is as follows:
| Number | Genotype | Phenotype |
|--------|----------|--------------------------|
| 346 | FSL / fsl | Red, heavy, large |
| 348 | fsl / fsl | White, light, small |
| 100 | FSl / fsl | Red, heavy, small |
| 100 | fsL / fsl | White, light, large |
| 50 | FsL / fsl | Red, light, large |
| 50 | fSl / fsl | White, heavy, small |
| 4 | fSL / fsl | White, heavy, large |
| 2 | FsL / fsl | Red, light, small |
**Based on these results, which of the following statements is correct?**
[ ] All the crossover classes are included; you need to analyze crosses and data to determine the gene order.
[ ] There are some gene conversion events present.
[ ] We can determine the gene order based on the crossover frequencies observed.
[ ] The genotype FSL/fsl gives the same phenotype as FSL/FSL.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F1131871b-8c87-406d-9807-6125c8d6ca38%2Fef11cb78-8633-40a4-988b-0b9cb57ffac4%2Fxsg5wwg_processed.jpeg&w=3840&q=75)
