What is a key difference between sexual and asexual reproduction?
Sexual reproduction involves two parents and leads to genetic variation, whereas asexual reproduction involves only one parent and produces genetically identical offspring.
What is the structure of DNA called, and what is it made of?
DNA has a double helix structure and is made of nucleotides, which consist of a sugar, a phosphate, and a base (A, T, C, G).
What is a gene?
A gene is a section of DNA that codes for a specific protein.
Explain how a person can inherit cystic fibrosis.
Cystic fibrosis is caused by a recessive allele, so a person must inherit two copies (one from each parent) to develop the disorder.
What are two factors that cause variation within a species?
Genetic factors: Differences in DNA from parents.
Environmental factors: Conditions such as diet, climate, and lifestyle.
What is meant by the term ‘natural selection’?
Natural selection is the process where organisms with advantageous traits survive, reproduce, and pass on their genes, while less adapted organisms are less likely to survive.
How does genetic engineering differ from selective breeding?
Genetic engineering involves directly modifying an organism’s DNA using biotechnology, while selective breeding involves choosing parents with desirable traits to breed naturally.
What is the main concern about genetically modified (GM) crops?
Concerns include potential harm to ecosystems, reduced genetic diversity, and possible long-term health effects.
How are organisms classified in the Linnaean system?
Organisms are classified into hierarchical groups: Kingdom, Phylum, Class, Order, Family, Genus, and Species.
What evidence supports the theory of evolution?
Fossil records, DNA similarities between species, and observations of natural selection (e.g., antibiotic resistance in bacteria).
