D) It does not segregate like other genes. E) Sister chromatids separate during mitosis.
Males have one mismatched 'pair' which is referred to as the sex chromosome. Males inherit a y chromosome from their father and an X from their mother, whereas females inherit an X from each parent. The trait on one chromosome can be blocked by the matching trait on the other chromosome in the pair.These 'matching' traits are called alleles. It is rare that we inherit a characteristic just from one pair of alleles.his is because they are passed on from the grandparents or even great-grandparents. The dimple trait which remained a recessive gene during the parents' conception, will have become a dominant gene during the grandchild's conception and therefore comes about in the form of a dimple.
