In the given case, if the trait is favorable, it will be passed on to the offspring over many generations, leading to a population of darker squirrels.
The mutation refers to the sudden modification in the DNA's nucleotide sequence. Some of the mutations are harmful, while some offer survival benefits to the species. The mutations that offer the adaptive or survival advantages are favored by natural selection and the species with this kind of mutations seem to reproduce and survive more in comparison to the species with no mutation.
Therefore, if the darker color fur would be beneficial to the squirrel, for example, it would be tough for the predators to locate the squirrel with darker fur, then they seem to survive more and the traits keep on passing from one generation to another.
Answer:
The correct answer would be - they can mate or reproduce and produce fertile offspring.
Explanation:
In the biological world, there can be certain species the might have different looking organism due to environmental condition such as weather, geographical change, and many more.
In such a case, The biological species concept help in determining if these organisms belong to the same species or not. According to this concept, different species are separated by pre and post-zygotic barriers and due to this they can not mate, or even if they mate there would be no fertile offspring.
It just takes one sperm cell to go into the female egg to then produce a baby
Answer: This is a case of incomplete dominance inheritance because we can asume that the tail length is a trait with 2 alleles (no tail and long), but is posible to see 3 fenotypes, long, no tail, and medium which can be consider as a half way between long and no tail.
The phenotypes that seem a mix of two traits have heterozygous genotype, in this case the two parental cats have genotype Ll (assuming L as the symbol for long tail) since they have medium tails
When 2 heterozygous individual cross, the proportions according to Mendel's laws is:
25% offspring: Homozygous dominant
25% offspring: Homozygous recesive
50% offspring: Heterozygous
This proportions are quit similar to those obtained in the exercise
2/11 = 18 % Long tail: LL
3/11 = 27% No tail: ll
6/11 =54% Medium tail: Ll
Answer:
Anchoveta feed on large zooplankton whereas sardines feed mainly on phytoplankton. Use this information to suggest why sardine numbers are less
likely to collapse during an El Niño event?
Reason why sardine are less likely to collapse during an El Nino event is as a result of sardine survival is neither dependent on zooplankton nor anchoveta rather sardine is dependent on phytoplankton which is not scarce
Explanation:
