Genetics Revision List
Understand and be able to use the following words in a
sentence:
DNA, cell, nucleus, gene, allele, chromosome, dominant, recessive,
homozygous, heterozygous, characteristic (trait), inherited, gamete, zygote,
Punnet square, normal distribution, bell-shaped curve, discrete(either/or)
variation, continuous variation, sex chromosomes, selective breeding, natural
selection, evolution, mammal, primate, bipedal, opposable thumb
Variation:
o Describe continuous variation
o Give examples of characteristics (traits) that exhibit continuous variation
o Draw and describe the shape of graph you would get if you drew a
frequency histogram of a characteristic that shows continuous variation
o Describe discrete variation
o Give examples of characteristics (traits) that exhibit discrete variation
o Draw and describe the shape of graph you would get if you drew a
frequency histogram of a characteristic that shows discrete variation
o Explain the difference between continuous and discrete variation and say
which would show less variation
Fertilisation, genetics and growth:
o Describe the relationship between genes, DNA and
chromosomes
o Understand that cells divide and that the process to produce
gametes is different to the process that produces more body
cells
o Be able to explain how genetic material in offspring is the
combination of the parents’ original genetic information
o Be able to put information into a punnett square to work out probability of
offspring carrying specific characteristics
o Show using a punnett square how there is always a 50% chance of
producing a boy or a girl
Adatpations, natural selection and evolution
o Describe adaptations and outline the process of natural selection
o Explain how useful characteristics are passed on to the next generation
and how less fit individuals die before they can pass on their genes
o List adaptations of a chosen organism and give details on how these
adaptations allow it to survive in it’s environment
o Be able to interpret the mammalian family tree and explain
relationships between the families
o List characteristics of early humans and explain the
differences between them and our ape relations
