The process in which the characteristics of species change over many generations, sometimes becoming new species.

Differences between individuals that are caused by the genetic material they inherit.

The process of creating offspring through the fusing of gametes.

Reproduction involving one parent, giving genetically identical offspring.

Sexual and asexual reproduction

Biology

Variation and genetic mutations

Natural selection at the genetic level

Mutations and evolution in bacteria

Pupils will learn about eukaryotic and prokaryotic cells, and that subcellular evidence, including from analysis of genomes, has led to the classification and sometimes reclassification of organisms into taxonomic groups from species to domains.

Pupils learned that the fossil record provides evidence of evolution from common ancestors through transitional species to modern species, and that the theory of evolution by natural selection can be used to explain phenotypic changes in populations of species over generations.

This unit covers genetic variation, comparing asexual and sexual reproduction. It explores mutations' impact on phenotypes, evolution through natural selection, and how scientific theories develop, explaining how advantageous traits lead to adaptation.

Variation and natural selection at the genetic level

Depiction or discussion of sex or sexual body parts, including sex education.

Depiction or discussion of sexual content

Differences between individuals’ genomes, caused by the genetic material they inherit, are called …

True or false? Evolution only occurs when there is genetic variation within a population of organisms.

Match the advantages and disadvantages to the correct examples.

Izzy: Sexual reproduction requires only one gamete.

Jacob: Asexual reproduction requires only one individual.

Jun: Sexual reproduction always produces two offspring.

Laura: Asexual reproduction only happens in bacteria.

The Oak pupils are discussing reproduction. Who is correct?

True or false? Organisms that reproduce asexually cannot evolve.

A mutagenic substance creates a mutation.

An error is made when the genome is copied.

The offspring inherit half of their genome from each parent.

Organisms that reproduce asexually can evolve when genetic variation arises in the population. How can genetic variation occur during asexual reproduction?

The complete process of making offspring is called {{}}.

Aisha: Reproduction only happens in plants and animals.

Lucas: Reproduction is a common life process in all living organisms.

Sofia: Bacteria just divide in two – that’s not reproduction.

When reproduction involves the fusing of gametes, it is called {{}} reproduction.

When two gametes fuse during sexual reproduction, this is called …

Each gamete carries __________ of the genetic material of the parent.
