Answer:

The answer to the given question is =7/8

Explanation:

In autosomal dominant traits, one copy of the affected gene is enough to cause the disease. Let ’A’ be the affected gene, ‘a’ be the non affected gene. Since IV-4’s parents are a couple of affected and non-affected. So, he has the genes Aa, i.e. a single affected gene.  

A a

a aA aa

a aA aa

Number of children affected=\frac{1}{2}

Number child affected out of three = (\frac {1}{2}) ^{3}

At least one child affected out of three = 1-P (number of children affected out of 3 )

                                                                      = 1-(1/2)^{3}

                                                                     = \frac{7}{8}  

So, the answer to the given question is 7/8

Proteins are polymers of _____. Proteins are polymers of _____. Nucleotides hydrocarbons amino acids ch2o units glycerol request
Nina [5.8K]

Proteins are polymers of amino acids. There are a fixed set of amino acids that are involved in the making of a protein. These amino acids are varied in number and type to give rise to different combinations in a polymer. This creates a diversity of protein molecules.

The amino acids link to other amino acid in the polymer through the formation of a peptide bond between them. It forms when the carboxylic group of one amino acid molecule reacts and binds to the amino group of the other molecule.
