Answer:

The correct answer is option B) "Species trees should be constructed using multiple loci (both nuclear and mtDNA)".

Explanation:

Gene genealogy is defined as the inference of relationships between individuals by using DNA testing in combination with the analysis of traditional genealogical and historical records. Gene genealogies could not be established using an unique genetic loci, since not always the same loci vary among individuals. Therefore, species trees should be constructed using multiple loci (both nuclear and mtDNA), to avoid erroneous inferences obtained by analyzing loci that do not vary among individuals.

What would happen if the pouter pigeon and the fantail pigeon and the fantail pigeon were selectively bred?

lozanna [386]

<h2>Answer:</h2>

The offspring population will contains the desirable characteristics of both fantail pigeon and the fantail pigeon.

<h3>Explanation:</h3>

The selective breeding is the planned breeding between two organism of the population with desirable properties to result in the new traits from both parents in the single next generation offspring.
In this case, the offspring of the pouter pigeon and the fantail pigeon will contain the traits of pouter and it also has fantail.
The new generation will be selective breed an it is from the breeding of intra specie organism. If breeding is inter specie than the offspring is most probably infertile.
