In cucumbers, dull fruit (D) is dominant over glossy (d) fruit, orange friut (R) is dominant over cream fruit (r), and bitter co
stiv31 [10]

Explanation:

  • Dull fruit (D) is dominant over glossy (d) fruit.
  • Orange friut (R) is dominant over cream fruit (r).
  • Bitter cotyledon (B) is dominant over non-bitter cotyledons (b).

The three genes are independent.

<h3>a)</h3>
  • A plant homozygous for dull, orange fruit and bitter cotyledons has the genotype <em>DDRRBB</em><em>.</em>
  • A plant homozygous for glossy, cream fruit and non-bitter cotyledons has the genotype <em>ddrrbb</em>.

100% of the F1 will have dull, orange fruit and bitter cotyledons and will be heterozygous for all genes: <em>DdRrBb</em>.

<u>The F2 will have 8 possible phenotypes:</u>

  • 27 D_R_B dull, orange fruit and bitter cotyledons
  • 9 D_R_bb dull, orange fruit and non-bitter cotyledons
  • 9 D_rrB_ dull, cream fruit and bitter cotyledons
  • 3 D_rrbb dull, cream fruit and non-bitter cotyledons
  • 9 ddR_B_ glossy, orange fruit and bitter cotyledons
  • 3 ddR_bb glossy, orange fruit and non-bitter cotyledons
  • 3 ddrrB_ glossy, cream fruit and bitter cotyledons
  • 1 ddrrbb  glossy, cream fruit and non-bitter cotyledons

<h3>b)</h3>

An F1 plant is crossed with a plant that has glossy, cream fruit and non-bitter cotyledons.

<h3>DdRrBb x ddrrbb </h3>

The F1 individual can produce 8 types of gametes: DRB, DRb, DrB, Drb, dRB, dRb, drB and drb. The cream fruit and non-bitter cotyledons individual can only produce drb gametes. This cross also produces a progeny with the following genotypes and phenotypic proportions:

  • 8 DdRrBb dull, orange fruit and bitter cotyledons
  • 8 DdRrbb dull, orange fruit and non-bitter cotyledons
  • 8 DdrrBb dull, cream fruit and bitter cotyledons
  • 8 Ddrrbb dull, cream fruit and non-bitter cotyledons
  • 8 ddRrBb glossy, orange fruit and bitter cotyledons
  • 8 ddRrbb glossy, orange fruit and non-bitter cotyledons
  • 8 ddrrBb glossy, cream fruit and bitter cotyledons
  • 8 ddrrbb  glossy, cream fruit and non-bitter cotyledons

Artist 52 [7]
The correct answer to the question about why can a Benedict solution be used to distinguish between a glucose and a sucrose is letter A. Benedict's Solution is used to test the presence of reducing sugar. Glucose is a reducing sugar while Sucrose is a non-reducing sugar since it has a glycosidic bonds between their structure that hinders the formation of open chain. In the end, Sucrose stuck at its cyclic form.
