Which of the following statements is correct? a)All animals share a common ancestor. b)Sponges are diploblastic animals. c)Eumet
Alecsey [184]

All animals share a common ancestor.  

Explanation:

According to various phylogenetic gene sequence analysis, there are various evidences that proved all animals originated from a common ancestor.

Initially, it was stated that all organisms descended from a single cell which then gave rise to multicellular organisms. Organisms that descend from a common ancestor are closely related and grouped.

The lineage of the common ancestor can be traced in the neoproterozoic era.

The last common ancestor or the basal animal was sea sponge according to some researchers. The last universal common ancestor is called as the concestor.

Which disappears more rapidly from a population, a deleterious dominant allele or a deleterious recessive allele?
Allisa [31]

Answer:

Selection is a directional process that leads to an increase or a decrease in the frequency of genes or genotypes. Selection is the process that increases the frequencies of plant resistance alleles in natural ecosystems through coevolution, and it is the process that increases the frequencies of virulence alleles in agricultural ecosystems during boom and bust cycles.

Selection occurs in response to a specific environmental factor. It is a central topic of population and evolutionary biology. The consequence of natural selection on the genetic structure and evolution of organisms is complicated. Natural selection can decrease the genetic variation in populations of organisms by selecting for or against a specific gene or gene combination (leading to directional selection). It can increase the genetic variation in populations by selecting for or against several genes or gene combinations (leading to disruptive selection or balancing selection). Natural selection might lead to speciation through the accumulation of adaptive genetic differences among reproductively isolated populations. Selection can also prevent speciation by homogenizing the population genetic structure across all locations.

Selection in plant pathology is mainly considered in the framework of gene-for-gene coevolution. Plant pathologists often think in terms of Van der Plank and his concept of "stabilizing selection" that would operate against pathogen strains with unnecessary virulence. As we will see shortly, Van der Plank used the wrong term, as he was actually referring to directional selection against unneeded virulence alleles.
