Inheritance Flashcards
Gametes
Sex cells
Gene
A section of the DNA
Inheritance
Traits genetically transmitted from parents to offspring
Variation
Any difference between cells, individuals, organisms or groups of organisms
Evolution
A change in the genetic composition of a population over several generation s
Meiosis
Number of chromosomes halved and combined with new genes from the sexual partner to produce unique offspring
Gene mutation
Occur continuously and on rare occasions can affect the functioning of the animal or plant
Genetic engineering
Taking genes from one species and introduce them in to the genome (complete set if genetic information)of another
Remain highly controversial
Reproduction
Making of an offspring
What happens during reproduction
Genetic info in the chromosomes is passed on from the parent to the offspring
Two different ways of reproducing
Asexual and sexual
Fertilisation
Fusing of a male and female sex cell
What does a fertilised egg cell form and what happens after?
A zygote which goes into develop into a new indicator
Plants can reproduce into two ways
Sexually and asexually
In plants male and female gametes are….
Male gametes = pollen
Female gametes = eggs
