What is mitosis?
Preserved remains of ancient organisms
What are Fossils?
The four nitrogenous bases in DNA
What are adenine, thymine, cytosine and guanine?
The study of genes and how they are expressed.
What is genetics?
The islands that Darwin visited on his voyage
What are the Galapagos islands?
A way of showing the likely genotypes of the offspring of a particular pairing when doing genetics problems.
What is a Punnet square?
When a species disappears from the earth entirely.
What is Extinction?
The basic building block of DNA
What is a nucleotide?
The combination of alleles an individual has for a gene, expressed in letters.
What is genotype?
A feature that helps an organism to survive or reproduce in its environment
What is an adaptation?
The 'father of genetics' who did experiments with pea plants.
Who is Gregor Mendel?
The process where favourable traits are 'chosen' by factors in the environment.
A well supported testable explanation for the way species change over time to better suit their environment
What is the theory of evolution?
The state of having two of the same allele for a gene.
What is homozygous?
The 'father of evolution'
Who is Charles Darwin?
The process where a cell divides to form four non-identical daughter cells.
Meiosis
The idea that individuals most suited to an environment will survive.
What is survival of the fittest?
Different related species of birds that had different shaped beaks depending on the island they were from
What are (Darwin's) finches?
The state of having two different alleles of a gene.
What is heterozygous?
The chemical molecule that contains the instructions for all life processes in your cells.
What is DNA?
A rod-like structure that contains many genes along it and which is made up of a long strand of DNA
What is a chromosome?
The area of research that compares the early stages of development of different species to determine evolutionary relationships.
What is embryology?
The passing on of traits from parents to offspring.
What is heredity?
The appearance or physiology of an organism, as determined by genes and environment.
What is phenotype?
