The question is incomplete. The complete question is as following:

Tay Sach's disease is a fatal genetic condition, in which affected individuals cannot metabolize fats properly. Children who inherit the disease rarely live past the age of five. The disease is caused by the presence of a homozygous recessive gene. If a child has Tay Sach's disease, what would her parents' genotypes be?

Answer:

Parents will have heterozygous genotypes

Explanation:

Tay Sach is an inherited genetic disorder that destroys nerve cells in the spinal cord and brain.

Children with Tay Sach diseases have a homozygous recessive gene, it means both parents would have heterozygous because they carry heterozygous for the dominant trait. If any one from the parent would have homozygous recessive gene, they would have died as children. it means there are 25% chance that their child will inherit Tay Sach's.

Hence, the parents would have heterozygous genotype.

The downfall of a tragic character is the result of __________.
ki77a [65]

The downfall of a tragic character is the result of <u>"a tragic flaw".</u>


The term hero is gotten from a Greek word that implies a man who faces affliction, or shows strength, despite risk. Nonetheless, at times he faces ruin too. At the point when a hero goes up against destruction, he is perceived as a tragic hero. Aristotle, the Greek philosopher, portrays these plays or stories, in which the principle character is a shocking saint, as disasters. Here, the hero goes up against his ruin whether because of destiny, or by his own oversight, or some other social reason.  

Hamartia refers to a tragic flaw that causes the downfall of a hero.
