Chapter 7, Problem 8GP
Summary Introduction

(A)

To determine:

The percent of the egg produced by a carrier female is affected with cystic fibrosis.

Introduction:

The allele is the form of a single gene present in an organism. The different combination of the alleles determines the genotype and phenotype of the organism. The allele can be of two types dominant or recessive. The dominant allele has a property to mask the effect of the recessive allele in heterozygote condition.

Summary Introduction

(B)

To determine:

The percent of the egg produced by a carrier male would carry a gene for cystic fibrosis.

Introduction:

The allele is the form of a single gene present in an organism. The different combination of the alleles determines the genotype and phenotype of the organism. The allele can be of two types dominant or recessive. The dominant allele has a property to mask the effect of the recessive allele in heterozygote condition.

Summary Introduction

(C)

To determine:

The probability of the offspring affected by the condition of cystic fibrosis.

Introduction:

The allele is the form of a single gene present in an organism. The different combination of the alleles determines the genotype and phenotype of the organism. The allele can be of two types dominant or recessive. The dominant allele has a property to mask the effect of the recessive allele in heterozygote condition. The cystic fibrosis is an autosomal recessive disorder, that occur by the inheritance of two affected or recessive alleles.

Summary Introduction

(D)

To determine:

If the probability of the offspring affected by the condition of cystic fibrosis is same as in part C.

Introduction:

The allele is the form of a single gene present in an organism. The different combination of the alleles determines the genotype and phenotype of the organism. The allele can be of two types dominant or recessive. The dominant allele has a property to mask the effect of the recessive allele in heterozygote condition. The cystic fibrosis is an autosomal recessive disorder, that occur by the inheritance of two affected or recessive alleles.

Respond to the following in a minimum of 175 words:  How might CRISPR-Cas 9 be used in research or, eventually, therapeutically in patients? What are some potential ethical issues associated with using this technology? Do the advantages of using this technology outweigh the disadvantages (or vice versa)? Explain your position.
