Why can’t the evolutionary relationships between certain species be explained thoroughly?

Biology
1 answer:
vredina [299]3 years ago

Answer:

Phylogeny: It is related to evolution dealings in the evolutionary development of a species. It is represented by different ways vertical or slanted.  

Phylogenesis: It refers to the evolutionary relationships among species.  

Phylogenetics: It is determination or estimation of evolutionary relationships among groups of species, organisms and genes.  

Phylogenetics is a field of biology which is used to find relationships among different organisms. This relationship is showing through a tree (used to model actual evolutionary relationship of organisms). Ancestral divided into two descendant species because closely related organisms are shown in near branches. If there is too much divergence between two species its mean they are not closely related.  

The history of speciation (one species becomes divided into more than one new species) tells us how these species are related to each other. If they evolve to be separate species relatively recently then they are "closely relative" similarly if they evolve to be separate specie long above then they are "distant relatives". For example orthologs are genes in different species that evolved from common ancestor gene by speciation; they retain same function in the course of evolution.

Explain why the genetic code is called a triplet code
salantis [7]
The genetic code is broken down into a series of codons on the mRNA. Each codon consists of 3 nucleotides which (normally) correspond to a single amino acid (e.g. AUG codes for methionine). I say normally because you can also have a codon indicate a stop codon (so no amino acid will be inserted and instead the polypeptide chain will terminate). This mRNA molecule with its list of codons will instruct a ribosome to synthesize a protein according to this code. 

This code is the set of rules - based on the triplet or codon. This triplet code is universal - all organisms use the same codons to specify the placement of each of the 20 amino acids in a protein.

What alternative form of genes do nucleic acids have that allows them to offer variability?
inna [77]

The answer to the above question is alleles.

<h3>What are Alleles?</h3>

The two nucleic acids in living things that are employed for conveying and storing genetic information are RNA and DNA. The genetic material in living things is called deoxyribonucleic acid (DNA), and it contains sections coding for beneficial proteins and products as well as carrying genetic information from one generation to the next. These chunks are referred to as genes.

However, genes also have a different form that is in charge of the genetic diversity in the qualities they are coding for. Allele refers to a gene's alternative or variant version. In a diploid creature like the human, each trait is encoded by genes that include contrasting pairs of alleles, allowing variation for that specific trait, i.e. two alleles for each gene. For instance, a gene with two alleles that codes for one of the human height traits includes the short variety (t) and the tall variety (T).
