Which of the following can arise from a zygotic mitotic problem in an individual with a normal XY genotype? Kleinfelter's syndrome. B Hermaphroditism. Male pseudohermaphroditism. D) Female pseudohermaphroditism. E Turner's syndrome.

in humans, as well as with many other animals, sex is determined by special sex chromosomes. An individuai containing two X chromosomes is a female, while an individual possessing an X and Y chromosome is a male. The 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 A 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 homoloque, 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…

Usually, if a gene that affects a particular genetic trait is NOT located on a sex chromosome, then consequently (click all that apply) it is an autosomal gene. a diploid cell should have at least two copies of this gene during G1 phase. this gene will be absent from the genomes of gametes. this trait should appear with roughly equal frequency in males and females. this trait must be “dominant.”

Which of the following conditions is not the result of a chromosomal alteration? ○ Chronic myelogenous leukemia (CML) ◇ Down syndrome (Trisomy 21) Turner syndrome O Mosaicism
