would a karyotype be useful for determining if a child has an autosomal recessive disorder like cystic fibrosis? briefly explain your answer.



Answer :

No a karyotype would not be useful for determining if a child has an autosomal recessive disorder like cystic fibrosis. Due to the organism's homozygous recessive status for both characters, which would cause it to exclusively produce "ry" gametes.

A person's karyotype is made up of all of their chromosomes. The phrase can also refer to an image created in a lab showing a person's chromosomes separated from one cell and organised in numerical order. A karyotype can be used to check for chromosomal number or structural abnormalities.

Two altered genes (mutations), one from each parent, are inherited in order to have an autosomal recessive condition. Usually, two carriers pass on these diseases. Although they only occasionally have health problems, they have one changed gene (recessive gene) and one unmodified gene (dominant gene) for the illness.

A illness called cystic fibrosis harms your lungs, digestive system, and other organs. A faulty gene causes the genetic disorder, which can be passed down through the generations. Cystic fibrosis has an effect on the cells that produce mucus, sweat, and gastrointestinal secretions.
