Variant for a character
Trait
Heritable feature that varies among individuals
Character
What is true-breeding
Homozygous breeding
Crossing of two true-breeding organisms
Hybridization
Alternate versions of a gene
Alleles
Law of segregation
Alleles separate during meiosis
Observable traits
Phenotype
Genetic makeup
Genotype
Heterozygous for one character as a result of breeding
Monohybrids
Heterozygous for two characters
Dihybrid
Law of independent assortment
Alleles separate independently
Offspring looks like one of two parents
Complete dominance
Alleles “blend”
Both kinda show
Incomplete dominance
Both alleles show fully in different spots
Codominance
Genes that have multiple phenotypic effects
Pleiotropy
Multiple alleles affect a phenotype
Polygenic inheritance
Range of phenotypic possibilities
Norm of reaction
Family tree used to track traits
Pedigree
Chromosome theory of inheritance
Genes have specific loci along chromosomes
Place for a gene on a chromosome
Locus
Phenotype most commonly observed in natural populations
Wild type
Gene located on specific chromosome
Sex-linked gene
Genes linked together in crosses
Linked genes
The production of offspring with combinations of traits that differ from those found in either parent
Genetic recombination
Offspring that match a parents phenotype
Parental type
Offspring with new combinations of phenotype
Recombinant type
Recombinant
1%=
1 map unit
Mishap in chromosome number
No disjunction
A zygote w abnormal no. Of chromosomes
Aneuploidy
Organism w more than two complete sets of chromosomes in all somatic cells
Polyploidy
Removes a chromosome
Repeats a chromosome
Reverses a segment
Rearrangement
Deletion
Duplication
Inversion
Translocation
A change in genotype Nd phenotype due to the assimilation of external dna by a cell
Transformation
Bacteria eaters
Bacteriophages
The replication of a DNA molecule begins at
Origins of replication
