When a genetic bottleneck happens, a species’ population ( blank ) . it’s unlikely that the species will have a high degree of ( blank ) , a population characteristic that provides a species with a greater chance of surviving changes to its environment. fill in the blanks

The right answers are : Declines (rapidly) and genetic diversity.

Phenomenon occurring when a population is greatly reduced over at least one generation. The low number of remaining breeders therefore transmits only a fraction of the initial genetic diversity to subsequent generations. This results in a genetic impoverishment of the population.

In conjunction with the founder effect, bottlenecks are one of the mechanisms of species evolution.

i believe it is "they are not used up by reactions" as the answer to your question, text me back if this is correct because i just learned this.

the answer is c.mitochondria. glad to .
