In humans, hemophilia is a sex linked trait. Females can be normal, carriers, or have the disease. Males will either have the disease or not (but they won’t ever be carriers) X”X’ x”Y = female, normal = male, normal X”X” x” Y = female, carrier male, hemophiliac x” x” X X = female, hemophiliac<\/p>\n\n\n\n

The Correct Answer and Explanation is :<\/strong><\/mark><\/p>\n\n\n\n

The given genetic cross describes the inheritance of hemophilia, a sex-linked recessive disorder, which is carried on the X chromosome. In this case, the different symbols represent individuals’ genotypes based on their sex chromosomes, where “X” refers to a normal X chromosome and “X'” represents the hemophilia allele on the X chromosome. Here\u2019s the breakdown of the cross:<\/p>\n\n\n\n

Parental Genotypes:<\/h3>\n\n\n\n
    \n
  • Female (X”X’) = A carrier of the hemophilia allele. She has one normal X chromosome (X) and one hemophilic X chromosome (X’).<\/li>\n\n\n\n
  • Male (X”Y) = A normal male, as males have one X and one Y chromosome, and the X chromosome is normal (X”).<\/li>\n<\/ul>\n\n\n\n

    Punnett Square:<\/h3>\n\n\n\n

    For the cross X”X’ x X”Y, we need to determine the possible offspring:<\/p>\n\n\n\n

    <\/th>X” (Mother)<\/th>X’ (Mother)<\/th><\/tr><\/thead>
    X” (Father)<\/strong><\/td>X”X” (female, normal)<\/td>X”X’ (female, carrier)<\/td><\/tr>
    Y (Father)<\/strong><\/td>X”Y (male, normal)<\/td>X’Y (male, hemophiliac)<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

    Explanation:<\/h3>\n\n\n\n
      \n
    • X”X” (female, normal)<\/strong>: This female inherits a normal X from both parents, so she is not affected by hemophilia.<\/li>\n\n\n\n
    • X”X’ (female, carrier)<\/strong>: This female inherits a normal X chromosome from her father and a hemophilic X from her mother, making her a carrier of the disorder but not affected by it.<\/li>\n\n\n\n
    • X”Y (male, normal)<\/strong>: This male inherits the normal X chromosome from his mother and the Y chromosome from his father, so he is not affected by hemophilia.<\/li>\n\n\n\n
    • X’Y (male, hemophiliac)<\/strong>: This male inherits the hemophilic X chromosome from his mother and the Y chromosome from his father, so he has hemophilia.<\/li>\n<\/ul>\n\n\n\n

      Key Points:<\/h3>\n\n\n\n
        \n
      • Hemophilia is a recessive trait on the X chromosome, which means males with the hemophilia allele on their only X chromosome will be affected.<\/li>\n\n\n\n
      • Females need two copies of the hemophilia allele (one on each X chromosome) to be affected by the disease, making them more likely to be carriers if they inherit only one allele.<\/li>\n<\/ul>\n\n\n\n

        Now, I’ll generate the image for this Punnett square.<\/p>\n\n\n\n

        Here is the generated image of the Punnett square showing the inheritance of hemophilia. It details the genetic cross between a carrier female (X”X’) and a normal male (X”Y), along with the possible outcomes for their offspring. Let me know if you need further explanation or adjustments!<\/p>\n\n\n\n
