Answer:

- Alelos:  

Locus 1: A (alto); a (enano)

Locus 2: B (púrpura); b (blanco)

- Cruzamiento parental: AABB  x aabb

Genotipos F1: AaBb

- Cruzamiento F1: AaBb x AaBb

Fenotipo: 100% plantas altas púrpuras

- Genotipos F2:  AABB (1/16); Aabb (1/16); aaBB (1/16); aabb (1/16); AaBb (4/16); AABb (2/16); aaBb (2/16); AaBB (2/16); Aabb (2/16)

- Fenotipos F2: 9/16 A-B- (altas púrpuras); 3/16 A-bb (altas blancas); 3/16 aaB- (enanas púrpuras); 1/16 aabb (enanas blancas)

Explanation:

Un cruzamiento dihíbrido refiere a un tipo de cruzamiento entre dos parentales que difieren para  dos pares de alelos (AABB x aabb). Si consideramos dos <em>loci</em> de dominancia completa, un cruzamiento dihíbrido producirá una F1 heterocigota para ambos genes donde la progenie expresará ambos rasgos dominantes. Como resultado de la distribución independiente expresada en la segunda ley de Mendel, La F2 de este tipo de cruzamiento producirá un proporción fenotípica 9:3:3:1; es decir 9 individuos con ambos rasgos dominantes (A-B-), 3 con el rasgo uno dominante (A-bb), 3 con el rasgo dos dominante (aaB-) y 1 con ambos rasgos recesivos (aabb).

Decide whether the discovery should be considered reasonable or surprising:
Readme [11.4K]

Answer:

A. Surprising.

Explanation:

The above scenario is completely surprising because there are 10 planets in solar system and considering all the orbit approximately in the same plane. But amazingly half (five) of the planets orbit counterclockwise, while remaining five planets orbit clockwise (opposite direction).

Reasonably, all planet should be orbit in same direction but it's surprising that in a same solar system half are orbit clockwise and half are anticlockwise.

Compare and contrast polysaccharides and nucleic acids in terms of monomer diversity and how they monomers are joined together
harkovskaia [24]

The monomer units of the carbohydrates vary in their total numbers extensively. Moreover, positions of the carbonyl groups along with the orientation of the hydroxyl groups also vary in the carbohydrates' monomers. The presence of any modification is also variable.

On the other hand, the nucleic acids have only 4 monomeric units. The linkages between the nucleic acid residues have less geometry than the glycosidic linkages.
