GENES YAPPING Flashcards
What makes a species
Reproduction good
What makes a population
Species same area
Gene pool
All the genes and alleles in the POPULATION
Allele frequency
Gene pool, how many times an allele shows up
Lateral gene transfer
Genes are swapped outside of reproduction, usually the single celled organisms cuz they’re weird
Polygenic
two or more genes (not alleles but the genes themselves)
Frequency questions approach how
Math and graphs and stuff
Evolution: Yap about gene duplication
If extra genes are copied with no bad effects then it makes more diversity with the genome
Evolution: yap about genetic rearrangement
Sequences can add, delete, or rearrange DNA and this constantly makes new code for new proteins
yap about hox genes and evolution
Homologous genes that code for early and important development in a lot of different animals
Evolution: yap about neutral mutations
They can be used to predict how related in time different species are, calculates “molecular clocks” and can compare how genes evolved over time
How to create accurate molecular clocks
Not easy, need to determine how often mutations occur and it’s different for every DNA
Why do polygenic traits show bell curves
More genes means more levels of intermediate phenotypes are possible
