Sexual reproduction |
The process of making offspring, using gametes from both a male and female |
|
|
Asexual reproduction |
A mode of reproduction by which offspring arise from a singal parent and inherit genes frkm that parent only |
|
|
Types of asexual reproduction |
Binary fission, regeneration (fragmentation), budding, vegetative propogation, spore formation |
|
|
Binary fission |
The process of asexual reproduction in which an organism reproduces by dividing into two individuals |
|
|
Regeneration |
The process in which specialised cells proliferate and make a large number of cells |
|
|
Vegetative propogation |
Asexual reproduction in which new plants are produced from roots, stems, leaves and buds (no seeds) |
|
|
Budding |
Asexual reproduction where an outward growth of an organism develops into a new individual |
|
|
Spore formation |
a spore germinates and develops into a new individual |
|
|
Mendels two laws |
Principle of segregation: two members of a gene pair (alleles) segregate from each other in the formation of gametes. Half the gametes carry one allele and the other half carry the other allele. 2) principle of independant assortment: genes for different traits assort independently of one another in the formation of gametes |
|
|
Co dominance |
Where both characteristics are displayed equally |
|
|
Incomplete dominance |
Neither gene is displayed fully. When two characyeristixs are displayed in an intermediate/mixed form |
|
|
Sex linked |
A gene on the x chromosome is affected: females only possess the trait if their father has the trait and passes on the affected 'X' chromosome as well as the mother. Males only have one x chromosome and will inherit the and will inherit the trait from the mother if she has the trait. |
