What type of reproductive isolating mechanism is described by a situation in which female fireflies mate only with males who emit light in a particular pattern?
A) habitat isolation
B) temporal isolation
C) mechanical isolation
D) behavioral isolation
<u>Answer:</u>
Behavioral isolation described by a situation in which female fireflies mate only with males who emit light in a particular pattern
<u>Explanation:</u>
Behavioral isolation restricts the features of a species from mating. It is the unitedness of various manners that guide to speciation. In this means, the features of a group conflict overtime in their actions. This proceeds continuously they can no extended mate. They then enhance separate varieties.
Behavioral isolation also inhibits varieties that simply conflicted from interbreeding. This retains the pair species from uniting to mature the identical species anew. For instance, Two frog varieties are existing in equivalent circumstances. Pair individuals from these associated varieties could technically mate. Yet, they do not mate due to behavioral barriers.
Because a theory is what might happen but a law is when you know what will happen every time
