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).

Answer:

(1) Amoeboid protozoans or sarcodines

They are unicellular, jelly-like protozoa found in fresh or sea water and in moist soil.

(2) Flagellated protozoans or zooflagellates

They are free living, non-photosynthetic flagellates without a cell wall.

(3) Ciliated protozoans or ciliates

They are aquatic individuals that form a large group of protozoa.

Which of the following are important features for transcription?
devlian [24]

Answer:

The correct answer will be option-A and B.

Explanation:

Transcription is a process which synthesizes a complementary molecule of DNA which acts a messenger called RNA.

The gene contains a sequence of the nucleotide at the beginning of gene called promoter sequence. The promoter sequence has the ability to attach an RNA synthesizing enzyme called RNA polymerase.

The RNA polymerase is the enzyme which synthesizes the RNA molecules using a single strand of DNA called template strand.  RNA polymerase binds nucleotide at 3' end of the strand thus proceeding the strand in 5' to 3' direction.  

The promoter and RNA polymerase begins the process of transcription and thus option-A and B is the correct answer.

After crossing purebred red (dominant) and purebred white (recessive) flowers, pink flowers appeared. Using symbols, show the cr
-Dominant- [34]
Since after crossing a red and a white flower produced pink flowers, the red color trait shows an incomplete dominance and has a genotype of Rr.
Using the Punnett to determine the cross between pink and white flowers:
   |   R   |   r   |
r  |  Rr  |   rr   |
r  |  Rr  |   rr   |

The results indicate that the cross between pink and white flowers will produce a ratio of 1:1

Rr x rr
