Mendelian Genetics Flashcards
Mendelian Traits
phenotypical features whose patterns of inheritance follow Mendel’s Theories inheritance of traits
Wisconsin Fast Plants
rapid cycling Brassicas used in wide array of research, including genetics
Domiant Gene ANL
determines presence of anthocyanin in Fast Plants, a purple pigment
Recessive Fast Plants
no anthocyanin present (anl/anl), appears as bright green color
Heterozygous or Homozygous Dominant Fast Plants
(ANL/anl) or (ANL?ANL)
purple phenotype expressed at varying levels
ROS
gene in fast plants that can determine size
Dominant or Heterozygous ROS
produces normal-length stemmed plants
(ROS/ROS) or (ROS/ros)
Homozygous recessive ROS
(ros/ros)
plants have very short stem, “dwarf”
Week one Lab activity
2 petri dishes are filled with a paper towel and then a type of seeds: one dish has the F1 generation while the other has the F2 generation; water was added and the dish had constant sun exposure for one week to observe the plants again later on
phenotype
observable characteristics
Genotype
genetic material/alleles of organisms
Dominant
dominant trait or gene, heritable (observable over recessive trait)
Recessive
heritable, masked by dominant trait unless combined with another recessive allele
Monohybrid cross
examines one trait
cross in F1 generation; two individuals with differentiating homozygous traits, domiant and recessive (TT x tt)
makes F2 generation
F2 generation cross; can exhibit four different phenotypes
Dihybrid cross
examines two different traits
F1 generation: forms from parental generation, predicted genotype is AaGg
F2 generation: (AaGg x AaGg), predicted genotype is varying, creates an F2 phenotypic ratio of 9:3:3:1
