Quick explanation
Define genotype and phenotype
- This point belongs to Genetics and ecosystems official content, especially Inheritance.
- You need to be able to define genotype and phenotype.
- The key ideas to know are phenotype and genotype.
- Use the linked flashcards and practice questions to check recall, then practise applying the idea in an exam-style answer.
Key concepts
Why it matters
This objective helps connect Inheritance to exam-style questions, flashcards, and revision notes for Genetics and ecosystems official content.
Quick student answer
Which of the following best defines the term 'genotype'?
Direct answer
The genotype refers to the genetic makeup of an organism, which includes all the alleles present.
Key terms
- Allele: Different forms of a gene that can exist at a specific locus on a chromosome.
- Dominant: An allele that expresses its phenotype even in the presence of a recessive allele.
Common trap
Confusing genotype with phenotype: Remember that genotype refers to the genetic makeup, while phenotype is the physical expression of those genes.
