Which one of the following statements is TRUE about Cystic Fibrosis (CF)?Group of answer choicesCF exhibits a recessive pattern of inheritance, where, in simple terms, two copies of the mutated gene are required for the disease to occur.CF exhibits a dominant pattern of inheritance, where, in simple terms, two copies of the mutated gene are required for the disease to occur.CF exhibits a dominant pattern of inheritance, where, in simple terms, only one copy of the mutated gene is required for the disease to occur.CF exhibits a recessive pattern of inheritance, where, in simple terms, only one copy of the mutated gene is required for the disease to occur.

Cystic fibrosis is a genetic disorder controlled by a single gene and it follows a simple recessive inheritance pattern.If C is the dominant allele (lacking cystic fibrosis) and c is the recessive allele (having cystic fibrosis) then which of the following statements are correct?CC – will suffer from the disease and can pass it on to offspringCc – will not suffer from the disease but can pass it on to offspringcc – will not suffer from the disease but can pass it on to offspringcc – will suffer from the disease and can pass it on to offspring

Cystic fibrosis is caused by the inheritance of recessive alleles depicted by a lower case ‘c’. Which of the following genotypes would result in an individual being affected by the condition?CFCcCCcc2What is the term for a person who has inherited a recessive allele for a disease, but is not affected by the condition? MutatorCarrierIncubatorMessenger3What is the genotype of a carrier for cystic fibrosis?  CFccCCCc4What percentage of the offspring of two cystic fibrosis carriers are likely to be affected by the condition?50%25%75%100%5The inherited disorder Huntington’s disease is controlled by a dominant allele, H. If one parent has a homozygous dominant genotype, what percentage of the offspring will inherit the condition?100%50%25%75%6If both parents are heterozygous for Huntington’s disease, what percentage of their offspring will inherit the condition?50%75%100%25%

The product of the cystic fibrosis gene affects the functioning of several different organs. Males with the disease may be infertile because the vas deferens did not develop properly early in life. Males also have a buildup of sticky mucus in the lungs as their disease progresses. An explanation for why these two different effects can be caused by the same gene is that the cystic fibrosis gene is ______.Multiple choice question.only expressed in adulthoodexpressed at different stages of developmentonly expressed in early embryonic life

Compare and contrast population and evolutionary effects on cystic fibrosis mutations and CCR5 mutations and whether these represent similar examples of genetic phenomena or are different with respect to natural selection in the human.

2. The allele that causes cystic fibrosis is recessive. An individual who is heterozygous for cystic fibrosisa. cannot reproduce.b. will have children who are all carriers of cystic fibrosis.c. is a carrier.d. cannot have children with cystic fibrosis.
