These have corresponding genes at every locus

What is a homologous pair?

100

Individual who produces offspring with the same trait every time it self-pollinates

What is true-breeding?

100

Phenotypes of hybrids is intermediate of phenotypes of true-breeding parents

100

Represented by two capital letters

100

Probability of male to female

200

An alternate form of a gene

What is an allele?

200

Process of determing genotype of a plant with a dominant trait by breeding with a recessive genotype

200

Two dominant alleles affect phenotype in separate & distinguishable ways

200

Represented by two lower case letters

This process produces haploid cells from a diploid cell

What is meiosis?

300

Experiment involving a cross between two heterozygous individuals for a single characteristic

What is the phenotypic ratio of a monohybrid cross?

400

This process of exchange results in recombinant chromosomes

What is crossing over?

400

Experiment involving breeding two individuals that are heterozygous for two genes

What is a dihybrid cross?

400

A gene at one locus alters phenotypic expression of a gene at a second locus

What is epistasis?

400

This genotype will result in the same phenotype as homozygous dominant

400

9:3:3:1

What is the phenotypic ratio of a dihybrid cross?

500

The term for which alleles are present in an individual at a particular gene

500

Genes that have multiple phenotypic effects

500

Determines phenotype in combination with genotype
