5Mitochondria are [blank_start]organelles[blank_end], responsible for the basic [blank_start]energy[blank_end] processing that goes on inside cells. They contain about [blank_start]0.05[blank_end]% of the DNA contained in chromosomes, which are called [blank_start]mtDNA[blank_end]. Unless the mitochondrial DNA [blank_start]mutates[blank_end], child has exactly the same mitochondrial genes as its [blank_start]mother[blank_end], because it does not recombine with DNA from the [blank_start]sperm cell[blank_end]. The accumulation of mutations allows us to derive the [blank_start]phylogenetic[blank_end] history of non-recombining sections of DNA, thus scientists can use [blank_start]mtDNA[blank_end] to reconstruct a tree of descent based on [blank_start]derived[blank_end] similarities. It is also possible to estimate the time that has passed since the last common [blank_start]ancestor[blank_end] of one or more [blank_start]species[blank_end].

- EThe movement of genes from one population to another, or from one part of a population to another, as the result of interbreeding.
10Gene flow is the [blank_start]movement[blank_end] of genes from one [blank_start]population[blank_end] to another, or from one part of a [blank_start]population[blank_end] to another, as the result of [blank_start]interbreeding[blank_end].
- Amovement
- Bpopulation
- Cpopulation
- Dinterbreeding
11What is the term used to describe the evolutionary development and diversification of a species or group of organisms, or of a particular feature of an organism?
- Acladistics
- Bphylogeny
- Cheredity
- Ddescent theory
- Econvergence
12Cladistics is a method of [blank_start]classification[blank_end] of animals and plants that aims to identify and take account of only those [blank_start]shared[blank_end] characteristics which can be deduced to have originated in the [blank_start]common ancestor[blank_end] of a group of species during evolution, not those arising by [blank_start]convergence[blank_end].
- Aclassification
- Bshared
- Ccommon ancestor
- Dconvergence
13DNA is arranged in a [blank_start]double-helix[blank_end] that includes a sequence of [blank_start]nucleotides[blank_end] along the DNA backbone. Nucleotides are [blank_start]nitrogenous[blank_end] base molecules that form [blank_start]pairs[blank_end] and bond together through hydrogen bonds. Normally, DNA is compacted through coiling into [blank_start]chromosomes[blank_end] in the cell nucleus. Humans have [blank_start]46[blank_end] chromosomes which come in [blank_start]23[blank_end] pairs, which includes approximately 3 billion nucleotide [blank_start]base-pairs[blank_end].

- Bmutation
- Cevolution
- Dadaptation

25The lottery principle: focuses on the [blank_start]unpredictability[blank_end] of the environment. Natural selection works on the [blank_start]current[blank_end] environment, meaning your adaptations are suitable for the here and now. But the environment changes- and it can be unpredictable. it may pay for you to gamble by introducing variation in your offspring- If the environment changes, you might be lucky and some of your offspring may be able to [blank_start]survive[blank_end] and [blank_start]reproduce[blank_end].
- Aunpredictability
- Bcurrent
- Csurvive
- Dreproduce
26The red queen hypothesis...
- Afocuses on the unpredictability of the environment
- Bproposes that variation is advantageous because organisms need to be able to evolve resistance to pathogens
- Cproposes that if you reproduce asexually, you create new genotypes and greater variations in your offspring
- Dwas first proposed by Gregor Mendel
- Eis a possible explanation for the evolution of sexual reproduction
27If you reproduce [blank_start]asexually[blank_end], there’s no way to get rid of these “bad” mutations, and you are stuck with them. If you reproduce [blank_start]sexually[blank_end], the shuffling of genes may mean that some of your offspring, by chance, end up getting most of the [blank_start]beneficial[blank_end] mutations while some end up getting most of the [blank_start]deleterious[blank_end] mutations. This means the offspring with all the good genes are more likely to [blank_start]survive[blank_end] and [blank_start]reproduce[blank_end].
- Aasexually
- Bsexually
- Cbeneficial
- Ddeleterious
- Esurvive
- Freproduce
28What is Bateman's Principle?
- AThat the sexes differ in their ability to reproduce offspring
- BThat the sexes differ in their reproductive limits
- CThat sexual dimorphism occurs when males compete with each other for females
- DThat females are limited by mates
- EThat males are limited by resources
29[blank_start]Females[blank_end] invest more in [blank_start]reproduction[blank_end] and can only produce a [blank_start]limited[blank_end] number of offspring, so they cannot afford to produce offspring with [blank_start]deleterious[blank_end] genes, and are therefore [blank_start]choosy[blank_end] about their partners.
[blank_start]Males[blank_end], on the other hand, can potentially reproduce relatively [blank_start]cheaply[blank_end] and can have almost an unlimited number of offspring- so it pays for [blank_start]males[blank_end] to [blank_start]compete[blank_end] to gain access to [blank_start]females[blank_end]. This is why we tend to see stronger selection in [blank_start]males[blank_end].- AFemales
- BMales
- Cfemales
- Dmales
- Emales
- Flimited
- Greproduction
- Hdeleterious
- Ichoosy
- Jcheaply
- Kcompete
30SNPs..

- Bare sections of DNA where we find variation in just one pair of nucleotides in a sequence
- Cgive you information on human genetic diversity
- Dstands for synthesised-nucleotide phenotypes
- Ewant Scottish independence
31Humans are genetically very [blank_start]similar[blank_end]. Many other studies confirm this. If you pick any 2 people from any population across the globe, on average, their genes will differ by only [blank_start]0.1[blank_end]%. There is greater variation [blank_start]within[blank_end] populations than [blank_start]between[blank_end] populations. Other studies estimate that around [blank_start]90[blank_end]% of [blank_start]genetic variation[blank_end] is found within a population, and [blank_start]10[blank_end]% between populations. There is greater genetic variation in [blank_start]Africa[blank_end] than anywhere else. If you pick two random individuals from [blank_start]Africa[blank_end], they are more likely to be genetically [blank_start]different[blank_end] from each other than if you picked a European person and a Chinese person and compared their genes.
