DNA and Genetics (ms Assari) Flashcards
Alleles
Different versions of the same gene
Asexual reproduction
Reproduction which requires only one parent; results in clones
Cancer
A disease which occurs at the result of cell changes that lead to uncontrolled growth and division
Clone
An organism which is genetically identical to its parent
Continuous variation
Variation which can take any value between a minimum and a maximum
Discontinuous variation
Characteristic which falls into distinct groups
Dominant allele
Version of a gene whose characterises is always expressed if present in the genotype
Environmental variation
Variation caused by the environment
Fertilisation
Joining together of two gametes
Gametes
Sex cells
Genetic cross
Technique used to show the possible characteristic of an offspring
Genetic variation
Variation caused by an organisms genetic material
Genome
All the genetic material present in an organism
Genotype
The combination of alleles present in an organism
Mutation
Change in the sequence of dna bases
