Genetics and inheritance
Aim: 1. To recall the important terms that
relate to genetics and inheritance (KS4)
2. Describe the basic structure of DNA
![Page 2: Genetics and inheritance Aim: 1.To recall the important terms that relate to genetics and inheritance (KS4) 2.Describe the basic structure of DNA](https://reader036.vdocuments.mx/reader036/viewer/2022062515/56649d235503460f949f9187/html5/thumbnails/2.jpg)
In your own words, explain the following terms
1. Chromosome2. Gene3. Features4. Gametes5. Zygote6. Diploid7. Allele8. Homozygous9. Heterozygous10. Selective breeding11. Genetic engineering12. Meiosis13. Mitosis14. Sexual reproduction15. Asexual reproduction16. Mutations17. Dominant 18. Recessive

The instructions that tell cells what we look like are carried in these. There are 23 pairs of them in a normal human cell.
![Page 4: Genetics and inheritance Aim: 1.To recall the important terms that relate to genetics and inheritance (KS4) 2.Describe the basic structure of DNA](https://reader036.vdocuments.mx/reader036/viewer/2022062515/56649d235503460f949f9187/html5/thumbnails/4.jpg)
These are the units which make up chromosomes. Responsible for inheritance of specific characteristics
![Page 5: Genetics and inheritance Aim: 1.To recall the important terms that relate to genetics and inheritance (KS4) 2.Describe the basic structure of DNA](https://reader036.vdocuments.mx/reader036/viewer/2022062515/56649d235503460f949f9187/html5/thumbnails/5.jpg)
These are things like eye colour, skin colour and hair colour.
They are controlled by genes.

Sperm and egg cells are both this type of cell.Contain half the amount of DNA of normal diploid cells
![Page 7: Genetics and inheritance Aim: 1.To recall the important terms that relate to genetics and inheritance (KS4) 2.Describe the basic structure of DNA](https://reader036.vdocuments.mx/reader036/viewer/2022062515/56649d235503460f949f9187/html5/thumbnails/7.jpg)
When a sperm and egg cell fuse together,
they produce this.

We use this word to describe cells which contain the full
complement of genetic material. In humans this would be
46 chromosomes (23 pairs)

The different versions of genes
![Page 10: Genetics and inheritance Aim: 1.To recall the important terms that relate to genetics and inheritance (KS4) 2.Describe the basic structure of DNA](https://reader036.vdocuments.mx/reader036/viewer/2022062515/56649d235503460f949f9187/html5/thumbnails/10.jpg)
Alleles of a given
gene are identical
(can be either
dominant or recessive
![Page 11: Genetics and inheritance Aim: 1.To recall the important terms that relate to genetics and inheritance (KS4) 2.Describe the basic structure of DNA](https://reader036.vdocuments.mx/reader036/viewer/2022062515/56649d235503460f949f9187/html5/thumbnails/11.jpg)
Alleles of a given gene are not identical
![Page 12: Genetics and inheritance Aim: 1.To recall the important terms that relate to genetics and inheritance (KS4) 2.Describe the basic structure of DNA](https://reader036.vdocuments.mx/reader036/viewer/2022062515/56649d235503460f949f9187/html5/thumbnails/12.jpg)
Where plants and animals with useful or desired traits are bred together
to produce offspring with those desired traits

The altering of the character of an organism by
inserting genes from another organism

Division of a cell to produce 2 daughter cells which each has the same
number and kind of chromosomes as the mother cell

Type of reproduction that involves fusion of gametes

Reproduction whereby
individuals are produced from a single
parent

Random change in the genetic material of the cell
![Page 18: Genetics and inheritance Aim: 1.To recall the important terms that relate to genetics and inheritance (KS4) 2.Describe the basic structure of DNA](https://reader036.vdocuments.mx/reader036/viewer/2022062515/56649d235503460f949f9187/html5/thumbnails/18.jpg)
The allele that is expressed where an individual is heterozygous
![Page 19: Genetics and inheritance Aim: 1.To recall the important terms that relate to genetics and inheritance (KS4) 2.Describe the basic structure of DNA](https://reader036.vdocuments.mx/reader036/viewer/2022062515/56649d235503460f949f9187/html5/thumbnails/19.jpg)
The allele that is ‘hidden’ (not expressed) when an individual is heterozygous
for a given gene

What does it look like?
