Answer:
C) The ancestral population probably had this type of blood pigment, but it was lost through genetic drift in the other 29 populations.
Explanation:
The presence of a blood pigment that is extraordinarily effective at carrying oxygen is a beneficial genetic trait and should be favored by natural selection. According to the given information, the organisms of only a single population of pupfish have this trait while the others do not have it.
This means that the trait was present in the ancestral populations of the pupfish but was lost in the other populations due to some accidental/chance event. Loss or fixing of an allele by a chance event is called genetic drift. It does not include any natural selection but results in a random change in the allele frequencies of a population. Therefore, loss of the trait by genetic trait might have occurred in the other populations.
The correct answer is option Memorization.
The memorization of the data help the scientist to recall all the facts and the theories, which are related to the experiments. In case, a scientist remembers all the things, the analyzing the data would be easier, as he can relate the data without referring to many sources. Hence, memorization would be very helpful in making connections across the data.
explanation/Answer:
If these factors existed, why didn't moose just keep getting bigger and bigger? Think of some possible reasons. Conflicting selection pressures such as joint weakness due to excessive size, metabolic problems with increased size, lack of genetic raw material for increased growth.
