Biogenesis, the fir tree began life when fertilization occurred to produce a singlee cell.
        
                    
             
        
        
        
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
 
        
             
        
        
        
They are very hard to understand so just stop making them
        
                    
             
        
        
        
This occurs through the process of cell specialization, where in some cells genes are active whereas in others they are not.
