Phenotype
A heritable feature that varies among individuals, such as flower colour.
What is a character?
Alternative versions of genes.
What are alleles?
Mendel's second law.
What is the law of independent assortment?
Each variant for a character, such as purple or white colour for flowers.
What is a trait?
Multiple genes affecting one character.
What is epistasis?
Mendel's first law.
Type of interaction that controls coat colour in mice.
What is recessive epistasis?
Two alleles at a locus producing two different phenotypes that both appear in heterozygotes.
What is codominance?
Two genes which work together to
produce a phenotypic effect.
What are complimentary genes?
Law caused by the movement of genes in gamete formation.
What is independent assortment?
Type of organism that has the highest number of chromosomes (double points if you can remember its scientific name).
What is the fern, Ophioglossum reticulatum?
Heterozygotes show an intermediate phenotype.
What is partial/incomplete dominance?
DNA type that makes up 97% of the human genome.
What is non-coding DNA?
The law that dictates that an organism with the genotype Aa, will create 50% A gametes and 50% a gametes.
What is independent assortment?
Mendel's secret third law
What is the law of dominance?
The process thought to be responsible for phenotypes before Mendel's experiments.
What is a blending of characters.
Statistical tool for testing whether an observed ratio is the same as the expected.
What is a chi-squared test?
The law that states "across loci, segregation of alleles at one locus will not affect other loci."
What is the law of equal segregation?
Mendel's first name.
What is Johann?
