Inherited Disorders (GCSE Biology)

Which technique produces genetically identical plants quickly from a single parent plant and is often used to preserve plants with desirable traits?

Which scenario is an example of natural selection acting on genetic variation in a population?

A genetic test detects whether an unborn foetus has inherited two copies of a recessive disease allele. What type of test that samples cells from the placenta is commonly used for this purpose during pregnancy?

Which of the following is an ethical concern commonly raised about genetic screening and testing for inherited disorders?

What is a likely consequence of inbreeding (mating of close relatives) in small populations regarding inherited disorders?

Cystic fibrosis (CF) is caused by a faulty CFTR gene and is inherited as a recessive trait. If two carrier parents (both heterozygous) have a child, what is the probability the child will have CF?

Which process explains how populations become better suited to their environment over many generations due to inherited differences?

Which term describes a person who carries a recessive disease allele but does not show the disease symptoms?

Which of the following is a likely effect of a mutation in a gene encoding haemoglobin?

In pedigree analysis, a disease that appears in every generation and affects both sexes equally is most likely to be inherited how?

Carrier screening can identify people who carry recessive disease alleles. What is a main benefit of offering carrier screening to couples planning a family?
