Question

In cucumbers, dull fruit (D) is dominant over glossy fruit (d): orange fruit (R) is dominant over cream fruit (r); and bitter cotyledons (B) is dominant over nonbitter cotyledons (b.) The three characters are encoded by genes located on different pairs of chromosomes. A plant homozygous for dull, orange fruit and bitter cotyledons is crossed with a plant that has glossy, cream fruit and nonbitter cotyledons. The F1 are mated to produce the F2.

What is the probability of dull, orange fruit with the bitter cotyledons in the F2?

probabilitoy of glossy orange fruit with nonbitter cotyledons in the F2?

Probability dull, cream fruit with bitter cotyledons in the F2?

Going to use these as references for study. Thanks

Explanation / Answer

1. dull,orange fruit with the bitter cotyledons in the F2 is-27 out of 64. 27/64 (DRB)

2. glossy orange fruit non bitter cotyledens in the F2 is -3 out of 64. 03/64 (dRb)

3. dull,cream fruit with bitter cotyledons in the F2 is --3 out of 64. 03/64 (Drb)
