When a species diverges into two new species over time. This is referred to as

Describe Reproductive based on adaptation and speciation. Give a real world example.

Assume you are studying secondary contact in two species of birds. You notice that hybrids are produced and that much of the DNA of each species is becoming more similar over time. The likely end point of this process is which of the following?     Fusion     Evolution of reproductive isolation     Reinforcement     Stable and minimal hybrid production

Describe and give example of Behavioural in Adaptation and Speciation

What is an example of how migration causes changes in gene frequencies?         Genetic material can become lost over time due to lack of reproduction when animals migrate.         When animals migrate, their genes mutate on their own, changing the frequency that a gene allele shows up.         When animals migrate, the mating becomes less random, causing inbreeding and, therefore, shifts in the proportion of alleles.         Seeds of plants are carried to different locations and introduced to a new population, adding their own genetic material and, therefore, changing gene frequencies.

According to the data table, which shows the number of differences in DNA for a small gene, which two species are most closely related? Number of Differences in DNA for 4 Species A B A 8 5 B 5 O species A and species C species B and species C O species C and species D O species A and species B

According the Red Queen hypothesis, a species must continually evolve if it is to continue to be able to survive. True False

Two populations of the same species of frogs have been separated by a mountain range for thousands of years. The females from one population are no longer attracted to the mating calls of the males from the other population. This is an example of which type of reproductive isolation mechanism? Temporal isolation Behavioral isolation Mechanical isolation Hybrid viability

Which of the following is a post -zygotic barrier that can cause reproductive isolation ? Two fish who live in different location in a lake and don't come into contact often enough to breed . Two fish who breed at different times of the year . The hybrid offspring of two fish species cannot reproduce .

Which of the following are post-zygotic reproductive barriers?a. Different mating songs prevent mate recognitionb. Species A breeds in Spring, Species B breeds in summerc. Species A and B mate, but the embryos die before hatchingd. The gametes of species A aren’t compatible with the gametes of species Be. Species A and B can mate and produce healthy offspring, but the offspring are infertile
