- C. A woman who has type A blood has a child with type AB blood. She is suing a man for child support who has type O blood. Is she suing the right man?A. In man, hemophilia, the "bleeder's disease" in which the time required for blood to clot is greatly prolonged, requires the presence of the recessive allele of a sex-linked (found on the X chromosome). Remember to list the genotypes and phenotypes of the sons and daughters separately. geneType of Inheritance: I Explanation: Punnett Square: II 2 III

- The likelihood that a son of a patient with severe hemophilia A will have hemophilia is:In humans, as well as with many other animals, sex is determined by special sex chromosomes. An individual containing two X chromosomes is a female, while an individual possessing an X and Y chromosome is a male. he sex chromosomes bear alleles for traits. Sex linkage applies to genes that are located on the sex chromosomes. These genes are considered sex-linked because their expression and inheritance patterns differ between males and females. The genes present on the X chromosome are said to be X linked. Many more genes are present on the X chromosome than found on the Y chromosome. Nonetheless, those genes found on the Y chromosome are said to be Y linked. The Y chromosome is smaller than its homologue, the X chromosome. Consequently, most of the loci present on the X chromosome are absent on the Y chromosome. 1. In humans, hemophilia is a sex linked trait. Females can be normal, carriers, or have the disease. Males will have the disease or not (but they won't be ever carriers) XH…Explain the following term: Homozygous:
