Two birds that look very similar to each other have always been considered two distinct species based on differences in their bo

dy size and in where they live. A group of ornithologists studying the two species begins to think they might not be separate species based on observed behavior. What would be the best next step regarding this new hypothesis?

The evaluation of their DNA and short tandem repeats will let them know if the birds are related or not. The genetic linkage will provide information about their common ancestry as well as if they belong to the same species, or are closely related species.

Answer:

A Genetic structure analysis

Explanation:

An analysis of genetic structure will help to know if these two groups are really different species. For that, some mitochondrial markers could be used first. Mitochondrial markers are used quite frequently for this purpose, since they usually show genetic preferences between different species. This is because they evolve faster than nuclear markers.

The Big Five trait dimension or the five factor model is based on descriptors of personality. The big five traits are:

Openness
Beuroticism
Agreeableness
Extraversion
Conscientiousness

From these, the trait expressed is Extraversion. This trait is characterized by outgoing and energetic behavior. Energy creation is gained through external means.

Match each definition to the appropriate term. locus
liraira [26]
I) Locus- the chromosomal site where a specific gene is located. A locus is a fixed position on a chromosome, like the position of a gene or a marker. Each chromosome carries ,many genes; human's estimated haploid (n) protein coding genes are about 20,000, on the 23 different chromosomes.


ii) Interference; the observed double crossover frequency differs from the expected double crossover frequency. Cross over interference is used to refer to the non-random placement of crossovers with respect to each other during meiosis. It results in widely spaced crossovers along chromosomes. Interference may exert its effect across whole chromosomes. As chromosomes in many eukaryotes are large, interference must be able to act over megabase lengths of DNA. 

iii) Linkage- the tendency for genes located in close proximity on the same chromosome to be inherited together. Normally when two genes are close together on the same chromosome, they do not assort independently and are said to be linked. Whereas genes located on different chromosomes assort independently and have a recombination frequency of 50%, linked genes have a recombination frequency that is less than 50%.

iv) Recombination- the process by which a new pattern of alleles on a chromosome is generated. Genetic recombination is the production of offspring with combinations f traits that differ from those found in either parent. During meiosis in eukaryotes, genetic recombination involves the pairing of homologous chromosomes. This may be followed by information transfer between the chromosomes.

katen-ka-za [31]

Answer:

Dissimilar organisms might have evolved from a distant, common ancestor.

Explanation:

First of all we should know species. Species is considered as a basic unit of taxonomic classification of an organism.

Initially, the scientists are agreed on this phenomenon that all distinct species are evolved gradually from common ancestor. Today, the species which are different from each other just like hummingbirds, humans and whales are from the same ancestor but with the time passage genetic mutation occurs and at the end dissimilar organisms we can see in our environment/surroundings.
