codominance | the alleles of gene pair in a heterozygous are fully expressed |
haploid cells | a cell that has half the usual numbers of chromosomes |
diploid cells | a cell that contains two complete sets of chromosomes |
sex-linked genes | genes that are in the sex chromosomes & that are inherited differently between males & females |
sex chromosome | chromosomes which determine the sex of individual organisms |
selective breeding | humans use animals/plant breeding to selectively develop particular phenotype traits |
inbreeding | the production of offspring from the breeding of individuals or organisms that are closely related genetically |
genetic engineering | altering the DNA in an organism's genome |
gene therapy | an experimental technique that uses genes to treat or prevent disease. |
genome | an organism's complete set of DNA, including all of its genes |
4 types of asexual reproduction | budding, binary fission, mitosis, regeneration |
budding | a new organism develops from an outgrowth or bud due to cell division at one particular site |
binary fission | fission, the DNA molecule divides and forms two DNA molecules. The cell then grows to create room for each molecule to move towards the opposite side of the bacterium. |
regeneration | the action or process of regenerating or being regenerated, in particular the formation of new animal or plant tissue. |
