- What is genetic disorders? Explain by giving an example.arrow_forwardAchondroplasia is an autosomal dominant disorder characterized by disproportionate short stature: the legs and arms of people with achondroplasia are short compared with the head and trunk. The disorder is due to a base substitution in the gene, located on the short arm of chromosome 4, that encodes fibroblast growth factor receptor 3 (FGFR3). Although achondroplasia is clearly inherited as an autosomal dominant trait, more than 80% of the people who have achondroplasia are born to parents with normal stature. This high percentage indicates that most cases are caused by newly arising mutations; these cases (not inherited from an affected parent) are referred to as sporadic. Studies have demonstrated that sporadic cases of achondroplasia are almost always caused by mutations inherited from the father (paternal mutations). In addition, the occurrence of achondroplasia is higher among the children of older fathers; approximately 50% of children with achondroplasia are born to fathers…arrow_forwardDifferentiate a multifactorial disorder from a chromosomal disorder.arrow_forward

- A girl and a boy were born to a young married couple. The girl is absolutely healthy. The examination of the boy's karyotype has shown 46 chromosomes. But one of the chromosomes of the 15th pair is longer than normal as a part of a chromosome from the 21st pair has joined it. How many autosomes and sex chromosomes are in the boy's karyotype?
