Stickleback fish found in lakes rapidly evolve a low armor plate morphology when compared to marine populations. analysis of the gene responsible shows that populations with low plating form one clade and marine populations form another. however, gene trees formed with other genes show that the low plating phenotype probably evolved independently multiple times. how have scientists resolved these contradictory gene trees? group of answer choices
a. the mutation first appeared in a single lake, but gene flow between lakes connected by rivers has spread the mutation to new populations where it increased in frequency.
b. all of the populations in lakes are very closely related. the other genes suggesting different topologies of relatedness are biased by geographic covariation.
c. mating between individuals of different populations has allowed introgression of the gene into many lake populations.
d. high armor evolved independently from a low armor state in the oceanic population, where it increased in frequency to near fixation.
e. a single origin of the low plating gene in the oceanic population that remained at a low frequency until lakes were colonized. then the gene independently became.

Option (e).

Explanation:

Evolution may be defined as the change in the species with respect to time. New characters are involved in the species according to their habitat and feeding habits of the species.

The contradictory gene tree can be solved by the study of evolutionary tree. The low plating gene might have single origin in the oceanic population. These genes remains in the low frequency but after the colonization of lakes, the genes fixed independently in each population.

Thus, the correct answer is option (e).

the father in the first generation probably had the recessive colorblind trait in his x chromosome. if he and his wife both had the colorblind trait, even if she had 1 recessive and 1 dominant, then that trait would be passed on to their kids.

(since you didn't attach the family tree this is just an assumption)

question: which statement best describes the different properties of metals?

answer: they are shiny and bend without breaking.

since metals have certain characteristics properties, they include the following: they are ductile, malleable, shiny, hard, lustrous, flexible and they are good conductor of heat and electricity. so therefore, metals are not dull and they are not non-flexible as listed. instead, they are shiny and flexible.

hope this , have a good day. c;
