Genetics Notes Flashcards
Gene
Segment of DNA that codes for a certain protein
Acquired characteristic
Phenotypic modification arising purely from environmental influences during developmental processes of an organism
Mono hybrid cross
A cross between two individuals involving one trait or character
Gametes
Sex cells
Determine the sex of an individual
Alleles
Pairs of genes that exhibit specific traits
Heredity
The process that all living organisms reproduce themselves. New individuals provide continuity of living organisms from one generation to the next
Phenotype
Phenotype is defined as the physical and psychological characteristics of an organism from both genetics and environment, or a group of organisms having like traits. An example of phenotype is a group of organisms which are all affected in the same ways by nature and nurture.
Genotype
Genetic makeup
Homozygous
having two identical alleles of a particular gene or genes
Heterozygous
having two different alleles of a particular gene or genes.
Yeast genus and species
Saccharomyces cerevisiae
Practical uses of yeast
Alcohol products Baking Biomass conversion Alternatives to fossil fuels High protein and vitamin B low meat diets
Anerobic
2 ATP
Without oxygen converts sugars and carbons to ethanol
Aerobic
36 ATP
With oxygen converts sugars and carbons to CO2 and H2O
Autolysis
Self digestion
