Document Summary

A: c)a large complex genome that allows for the creation of billions of possible mutations. Wild types: phenotype that is commonly seen out in nature. Wild type does not mean dominant trait, can be a recessive trait (ex: dwarfism is wild type but we are all not 3 ft tall) Pure breeding lines mean you have only 1 allele (ex: yy or yy, not yy) Selfed means pollunating with itself so f1 is yy and is mating with itself, so it"s a yy crosed with yy. Selfed is a 1:2:1 ratio, 25% to 50% to 25%, or to to . Do not need to memorize the 7 phenotypes mendel studied, just have idea of what he studied. Zygote: fertilized egg, first cell that could become progeny. Somatic cells are found everywhere except for sex cells. Start with 2n and end with 2n (look exactly like parent cell, genetically identical) One progenitor cell -> 2 genetically identical cells.
