AQA GCSE Biology 4.6 Inheritance, variation and evolution overview quiz quiz

It is faster than asexual reproduction

It produces genetic variation

It needs only one parent

It produces identical clones

Two genetically identical cells with the full chromosome number

Four genetically identical cells, each with the full number of chromosomes

Four genetically different cells with half the chromosomes

Two cells, each with double the normal number of chromosomes

A single straight strand of bases with no twist

A simple ring of bases joined end to end

A solid block of protein folded into a compact shape

A polymer of two strands in a double helix

The entire genetic material of the organism

A single gene that codes for just one protein

One chromosome found within the nucleus

A type of protein built from amino acids

A random mutation makes some bacteria resistant, and they survive and reproduce

The bacteria deliberately choose to become resistant when the antibiotic is used

The antibiotic makes every single bacterium in the population stronger and tougher

Bacteria are simply unable to ever become resistant to any antibiotic at all

It increases the genetic variation in the population by far too much

It reduces the gene pool and can cause inbreeding problems

It only ever works on bacteria and never on plants or animals

It transfers genes from one species directly into another species

Breeding cows that produce more and more milk over many generations

Choosing the tastiest tomato plants each year and saving their seeds to plant

Inserting a human insulin gene into bacteria so they make insulin

Letting a wild population evolve naturally over a long period of time

The plant, animal and fungus kingdoms

Kingdom, phylum and class groupings

Genus, species and family groupings

Archaea, Bacteria and Eukaryota

By a two-part Latin name of genus then species

By their everyday common name in English language only

By the kingdom that the organism belongs to

By a unique number given to each organism
