Answer:
See the answer below
Explanation:
Let the disorder be represented by the allele a.
Since the disease is an autosomal recessive one, affected individuals will have the genotype aa and normal individuals will have the genotype Aa or AA.
Since the four adults are carriers, their genotypes would be Aa.
Aa x Aa
Progeny: AA 2Aa aa
Probability of being affected = 1/4
Probability of being a carrier = 1/2
Probability of not being affected = 3/4
(a) The chance that the child second child of Mary and Frank will have alkaptonuria = 1/2
(b) The chance that the third child of Sara and James will be free of the condition = 3/4
(c)
(d) If someone has no family history of the disorder, their genotype would be AA.
AA x aa
4 Aa
<em>The chance that a child with alkaptonuria will have an offspring with alkaptonuria if the child's mate has no family history </em>= 0
(e)
(f) <em>The chance that a child with alkaptonuria will have an offspring with alkaptonuria if the child's mate has no family history</em> = 0

Answer:
Cancer is a disease in which abnormal cells divide uncontrollably and destroy body tissue.
Explanation:
Cancer is caused by gene mutations, which are sometimes caused by inherited gene mutations (ones you are born with), or mutations that occur after birth (i.e smoking, being overweight, chronic inflammation, viruses, cancer-causing chemicals (carcinogens), hormones, and lack of exercise.)
Your habits (drinking alcohol frequently etc. )
And family history are the main influences of cancer.
However, inherited cancer is usually rare.
