DNA
The Base Adenine pairs with:
Thymine
This type of trait is least likely to be expressed in a population
Recessive
What is the term for the observable characteristics of an organism, such as eye colour or height?
Phenotype
What is the term for the gradual change in a species over time, often resulting in new species?
Speciation
Complete the Complementary Base pair Sequence: ATGCTGCATGTGTA
TACGACGTACACAG
What are the different versions of a gene called?
Alleles
What is the term for the genetic make up of an individual e.g Aa or aa
Genotype
Name the term for an environmental impact that may cause Natural Selection
Selection Pressure
Name the structure that provides support to DNAs double helix:
Sugar Phosphate Backbone
What is the structure that carries genetic information in living organisms?
Chromosome
If a mother has the genotype X₁X₁ and a father has XᵧY, what is the probability of their offspring being male?
50%
What is the term for the process in which organisms with traits better suited to their environment survive and reproduce more successfully?
Natural Selection
State the full name for DNA
Deoxyribonucleic Acid
What is the term for an individual who carries one allele for a recessive genetic condition but does not express the condition?
Carrier
If a person has one dominant allele for a trait (e.g., A) and one recessive allele (e.g., a), what is their genotype?
heterozygous Aa
What is the term for structures in different species that have the same origin but may have different functions, such as the human arm and the bat wing?
Homologous Structures
What is the term for the process by which DNA makes an identical copy of itself before cell division, and the process by which somatic cells divide?
DNA Replication, Mitosis
What is the term for the physical exchange of genetic material between homologous chromosomes during meiosis?
Crossing Over
What is the name of the process that produces gametes (sperm and egg) in humans and other sexually reproducing organisms?
Meiosis
What is the concept in evolutionary theory that explains how new genetic variations arise in a population, potentially leading to new traits and adaptations?
Mutations
