- 8. The diagram below shows a pedigree of cystic fibrosis (CF), in which the black colour indicates the presence of CF. What is the probability that the individual labelled X is a carrier of CF? a) 100% b) 50% c) 25% d) 0%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…Patient D died shortly after birth, with a multitude of anomalies, including microcephaly, low set malformed ears, bilateral harelip, cleft palate, and congenital heart defects.
