6 0

Answer:

The natural selection on polygenic traits affects selection.

Explanation:

The natural selection process allows changes in frequencies of alleles in a character that is determined by single gene. The polygenic characteristics are disproportionately affected by natural selection as natural selection affect the phenotype distribution.

This occurs in three ways that are disruptive selection, stabilizing and directional selection.

A phylogenetic tree can be described as a diagram which depicts evolutionary histories among organisms of different species. The organisms which are more closely related are more closer to one another in a phylogenetic tree.

Human, chip, gorilla, orangutan all are greater apes whose complete DNA have been sequenced. The sequencing of their genomes showed that humans have the closest relationship with chimpanzees. Hence, scientists believe that humans might have evolved from the chimpanzees.

When two genes from two different people are sequenced and aligned, it is discovered that there are multiple sequence difference
ikadub [295]

Answer:

On the basis of the phenomenon of the degeneracy of codons, the coding of single amino acid can take place by various codons like four different codons, that is, CCC, CCU, CCG and CCA can code for single amino acid proline.  

In case, if there is a mutation in DNA, due to which CCA get transformed to CCG, even in such case coding for the same amino acid proline will take place. Hence, one can conclude that at the level of DNA mutation is taking place, however, the same is not getting witnessed in a protein, and that is why such kind of mutations are termed as silent mutation.

Answer:

cada célula tendrá dos núcleos

Explanation:

El complejo o aparato de Golgi es un organela compuesta por un grupo de membranas apliladas una sobre la otra formando una serie de sacos aplanados. El complejo de Golgi tiene diversas funciones: maduración, modificación (glicosilación), transporte y secreción de proteínas. En células vegetales, el aparato de Golgi sintetiza vesículas que forman parte del tabique telofásico el cual sirve para dividir el citoplasma de células vegetales durante la citocinesis. En consecuencia, si se eliminara esta organela, el tabique telofásico no se formaría y las células resultantes estarán compuestas por dos núcleos.
