Inheritance and Genetics Flashcards
Sexual Reproduction
Reproduction that involves two parents and creates genetically distinct offspring
A-sexual reproduction
Sexual reproduction with only one parent that gives genetically identical offspring
Meiosis
Mitosis but splits twice without reproducing another set of DNA giving two haploids
Variation
The variation that occurs with some random genetic mutations
Diploid
A cell with two sets of chromosomes to make a full set of chromosomes
(46 with humans)
Haploid
Half the full amount of chromosomes (one set)
23 with humans
Chromosomes
The structure that DNA is packed into and code for one characteristic
Malaria mitosis Asexual repro
In human mitosis in the red blood cells until they rupture and this posses is repeated
Malaria Sexual repro
This is in the mosquito when is feeds off another human and the two different malaria strains sexually reproduce with gametes

Embryo Screening
Amniocentesis -
15-16 weeks pregnancy takes fluid from around
embryo for Genetic material
Chorinic Villus
10-12 weeks in pregnancy takes small cell sample of
cells from the placenta
Embryo Screening Risks + concerns
can give false positives and negatives and therefore wrongly destroyed embryos
Could give the ability to select characteristics intelligence and height (superior race)
