The purpose of cross testing is to determine whether an individual is homozygous dominant/recessive or heterozygous dominant/recessive. Explain the events in meiosis that explain the law of segregation and the law of independent sorting.
What is a cross test for?
A test cross is a way of examining an organism’s genotype. The early use of the test cross was an experimental mating test used to determine which alleles are present in the genotype.
What is a cross test quizlet?
test cross. A genetic cross in which a test organism exhibiting the dominant trait is crossed with an organism exhibiting the recessive trait is used to determine whether the test organism is homozygous dominant or heterozygous.
What is the reason for a cross test quizlet?
What is the reason for cross testing? Use a Punnett square to predict offspring in a cross between a dwarf pea plant (homozygous recessive) and a large pea plant (heterozygous).
What is a genetic cross test?
Cross testing is another fundamental tool developed by Gregor Mendel. In its simplest form, a test cross is an experimental cross between a single organism with a dominant phenotype but unknown genotype and an organism with a homozygous recessive genotype (and phenotype).
