Glycine glycine - Silent mutation. Lysine stop; - Nonsense mutations. Silent mutations are caused by a point mutation and have no effect of the function because they code for the same amino acid. Missense mutations are caused by a point mutation and result in a different amino acid to be placed in the protein. Nonsense mutations is caused by a point mutation and cause a stop where there should not be one. The Frame shift mutations on the other hand are caused by insertion or deletion of a nucleotide causing a reading frame to shift and the protein to be too long or too short.
<u>Renaissance women had less freedom than men</u> ↔ Low class women were expected to be housewives and take care of everything to do with the house. Working-class women were expected to help their husbands run their business. They were denied all political rights and considered legally subject to their husbands.

These undesirable substances can be biological, physical or chemical.
Answer:
a) The genotype of her father = "aa".
The genotype of her mother = "Aa".
The genotype of Sally is "Aa".
b) 1/2
c) 1/2
Explanation:
a) Sally's father has alkaptonuria. So, the genotype of her father is "aa". Her mother is normal. Since her brother is affected by the disease, he should be homozygous recessive (aa). This means that the mother also has one copy of "a" allele and is heterozygous dominant (Aa). A cross between Aa (mother) and aa (father) would give 50% affected progeny with "Aa" genotype. So, the genotype of Sally is "Aa".
b) The genotype of her mother= Aa
The genotype of her father = aa
Aa x aa = 1/2 Aa (affected): 1/2 aa (normal)
So, if Sally's parents have another child, there is a 1/2 probability that this child will have alkaptonuria.
c) The genotype of Sally = Aa
Genotype of the man Sally marries= aa (since he is affected with alkaptonuria)
Aa x aa= 1/2 Aa (affected): 1/2 aa (normal)
There is a 1/2 probability that their child will have alkaptonuria.
