Identify the isolation mechanisms described using the drop-down menus. Differences in courtship or other behaviors prevent matin
lana [24]

Answer:

First, let's add the missing piece of information

Identify the isolation mechanisms by labeling either Geographical, Behavioral, Temporal, or Anatomical from the drop-down menu

The correctly identified mechanism is

1. Behavioral

2. Geographical

3. Temporal

4. Antomical

Explanation:

Differences in courtship or other behaviors prevent mating.- our answer is Behavioral

(Behavior isolation is the term used to describe reproductive isolation as a result of variations in courtship behaviours between the members of the same species occupying the same region).

Species can no longer interact because they are separated by physical boundaries.- it is Geographical

(Geographic isolation is seen in situations where the two populations of the same species get isolated by a geographical barrier such as mountain, island or river. This results in an inability to breed between the two populations as they become distinct new species).

Species do not interbreed because they breed at different times. this is definately Temporal.

(Temporal isolation is a form of reproductive isolation due to mating at separate times and seasons among two populations of the same species).

Species cannot physically mate due to genitalia or gametes being incompatible. And the correct answer is Antomical.

(Anatomical isolation

It is observed in situations when two populations of the same or distinct species cannot interbreed due to physical features such as genitalia and gametes formed in the organisms that make them uniquely separated).

Yes! this is the right answer. I just solved this question and its CORRECT.

How this organism are related
djverab [1.8K]

Answer:Generally, the longer ago the last common ancestor lived, the less the organisms have in common. Turtles and tortoises share a common ancestor, but began evolving separately a long time ago. ... Scientists can compare the DNA of two organisms; the more similar the DNA, the more closely related the organisms.
