Answer:

Gene flow or allele flow is the transfer of genes or genetic variation among populations.

This gene flow or migration of genes help maintain the similarities between the species or genetic diversity in a population but slows the process of speciation and variation in the population.

The causes of gene flow are:

1. Random mating- random mating among organisms of different population causes movement of alleles in populations.

3. Recombination of chromosomes during meiosis- can change the alleles of the organism.

2. Mutation- mutation in DNA can create new alleles in a population.

4. Random fertilization.

Reika [66]

Answer;

Two organisms that are placed on distantly spaced twigs on a phylogenetic tree are distantly related. They don't share the most recent common ancestor.

Explanation;

A phylogenetic tree is a diagram that describes the evolutionary relationships among carious species, based on the information available to and gathered by systematists. Should be viewed as hypotheses.

-The pattern of branching in a phylogenetic tree reflects how species or other groups evolved from a series of common ancestors. In trees, two species are more related if they have a more recent common ancestor and less related if they have a less recent common ancestor.

Streptomycin and fluoroquinolone would be contraindicated. Both rifampicin and pyrazinamide are not derivative of penicillin. </span>
