Hey there! Simply put, inherited traits come from an ancestor, and acquired are ones that are earned through adaption. Hopefully that makes sense. :)

The earliest classification systems grouped organisms based on

Paul [167]

Answer:

On the basis of physical traits.

Explanation:

Newer classification systems classify organisms on the basis of physical traits of an organism. All modern classification systems gets their concept and help from Linnaean classification system. In these new classification systems, those organisms that have similar characteristics are placed in one group because they evolve from the same ancestor or having common ancestry. These changes occurs in the organisms with the passage of time that helps organisms to survive in that environment.

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.

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

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
