The correct answer is option D, that is since genetic drift is random, it does not always favor the better or healthier organisms.
A mechanism of evolution in which the frequencies of alleles of a population change with generations because of sampling error is known as genetic drift. It takes place in all the populations of non-infinite size, however, its influences are strongest in small populations.
Answer:
The answer is option D.
Explanation:
A component of development in which the frequencies of alleles of a populace change with ages due to examining blunder is known as hereditary float. It happens in every one of the populaces of non-limitless size, be that as it may, its persuasions are most grounded in little populaces.
Answer:
1. What is the relationship between chromosomes and DNA? The chromosome is a molecule formed by a chain of DNA associated with proteins. Together, they form a group of molecules directly responsible for heredity.
2. What is heredity? It is the biological process where the genes present in a DNA are transmitted by parents to their children, through the division of gametes. These genes carry the codes that form the genotypic and phenotypic characteristics, which allows a similarity between parents and children to occur.
3. What is the role of proteins associated with the DNA molecule that makes up the gene? Proteins are responsible for keeping the DNA line tightly compressed, maintaining the chromosome structure. In addition, they control the activities of the genes present in this DNA molecule, being essential in maintaining heredity.
4. How do chromosomes participate in gene transmission? As mentioned above, genes are part of DNA and DNA is the molecule that makes up chromosomes, in this case, chromosomes are molecules loaded with genes. In the human body, cells have 46 pairs of chromosomes, with the exception of gametes that have half that number. During the reproductive process, the gametes (reproductive cells) divide and produce a new being. The mother's gametes unite with the father's gametes to form a new being. Each gamete has 23 chromosomes, which contain the genes responsible for transmitting the characteristics.

Answer:
White blood cells are the cells which play an important role in providing immunity to the body. The WBC can be categorized into five types which perform distinct functions in immunological response.
In the given question, since the WBC is engulfing the bacteria particle by the process of phagocytosis. The WBC contains cytoplasm and bilobed nucleus, therefore, this could be wither a neutrophil or eosinophil.
because the probability of hemophilia would be 1:2
because the probability of hemophilia would be 100%
Answer:
Because the probability of hemophilia would be 1:4
Explanation:
Hemophilia is a disease that comes with a sex chromosome (pair 46).
It is a recessive allele associated with chromosome X, women have two X chromosomes they can carry it, but they don't have it because they have another dominand allele non-hemophilic.
If you draw a Punnet square with a non-hemophilic father and a carrying mother, you'll found you have 1:4 chances of having a baby boy with hemophilia.
Carrying mother = X(H)X(h)
Father = X(H) Y
A carrier woman has a 50% chance to pass the hemophiliagene to her son. Hemophilia, a sex-linked disorder, impairs blood clotting leading to excessive bleeding. Therefore, surgeries like circumcision that cause significant bleeding should be avoided.
A woman carrying the hemophilia gene can indeed pass it on to her son. Hemophilia is a sex-linked genetic disorder predominantly occurring in males. The reason being, the defective gene causing this condition is located on the X chromosome, and males have one X chromosome received from their mother and one Y chromosome from their father. If the X chromosome obtained from the mother carries the hemophilia gene, the male child will develop the disease. This is because males lack a second X chromosome that can compensate for the one carrying the defective gene.
If a woman who carries the hemophilia gene has a son, there is a 50% probability that the son will have hemophilia. That's why it's essential for such a woman to take precautionary measures. Circumcision is a surgical procedure which involves significant bleeding. In cases of hemophilia, blood clotting is impaired, leading to a high risk of excessive and prolonged bleeding. Therefore, it would be a wise decision to avoid circumcision where there is a risk of the boy having hemophilia.
