Answer:
The process by which diploid cells undergo and produce haploid gametes is called meiosis.
1. Meiosis is a type of cell division that occurs in the reproductive cells, also known as germ cells.
2. The primary purpose of meiosis is to reduce the chromosome number in half, resulting in the formation of haploid cells.
3. Diploid cells contain two sets of chromosomes, one from each parent, while haploid cells contain only one set of chromosomes.
4. Meiosis consists of two rounds of division, known as meiosis I and meiosis II.
5. During meiosis I, the homologous chromosomes pair up and exchange genetic material in a process called crossing over.
6. This genetic exchange promotes genetic diversity and creates new combinations of genes.
7. After crossing over, the homologous chromosomes separate, resulting in two haploid cells with duplicated chromosomes.
8. Meiosis II is similar to mitosis, where the duplicated chromosomes line up and separate, producing four haploid cells.
9. These four haploid cells are the gametes, such as sperm or egg cells, which are used in sexual reproduction.
10. When two gametes fuse during fertilization, the resulting zygote will have the full diploid chromosome number again.
Overall, meiosis allows for genetic variation and ensures the production of haploid gametes necessary for sexual reproduction.
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.
