DNA
These have corresponding genes at every locus
What is a homologous pair?
Individual who produces offspring with the same trait every time it self-pollinates
What is true-breeding?
Phenotypes of hybrids is intermediate of phenotypes of true-breeding parents
What is incomplete dominance?
Represented by two capital letters
What is homozygous dominant?
Probability of male to female
What is 1:1?
An alternate form of a gene
What is an allele?
Process of determing genotype of a plant with a dominant trait by breeding with a recessive genotype
What is a testcross?
Two dominant alleles affect phenotype in separate & distinguishable ways
What is codominance?
Represented by two lower case letters
What is homozygous recessive?
1:2:1
What is the genotypic ratio of a monohybrid (F1) cross?
This process produces haploid cells from a diploid cell
What is meiosis?
Experiment involving a cross between two heterozygous individuals for a single characteristic
What is a monohybrid cross?
When characters vary along a continuum in a population
What is polygenic inheritance?
Represented by a capital letter and a lowercase letter
What is heterozygous?
3:1
What is the phenotypic ratio of a monohybrid cross?
This process of exchange results in recombinant chromosomes
What is crossing over?
Experiment involving breeding two individuals that are heterozygous for two genes
What is a dihybrid cross?
A gene at one locus alters phenotypic expression of a gene at a second locus
What is epistasis?
This genotype will result in the same phenotype as homozygous dominant
What is heterozygous?
9:3:3:1
What is the phenotypic ratio of a dihybrid cross?
The term for which alleles are present in an individual at a particular gene
What is genotype?
Generation produced by crossing two true-breeding parents
What is F1 (first filial) generation?
Genes that have multiple phenotypic effects
Determines phenotype in combination with genotype
What is environment?
Phenotypic ratio of F1 when alleles show incomplete dominance
1:2:1
