________ square: a diagram to predict the outcomes of a cross between two individuals and their traits.
Genotype
________: the gene sequence that determines the characteristics of an organism.
Phenotype
________: the detectable characteristic of an organismMendelian Principles.
Monohybrid cross
________: a cross between individuals that differ in only one trait.
Dihybrid cross
________: cross between individuals that differ in two traits.
The product rule
the probability of two independent events occurring together can be calculated by multiplying the individual probabilities of each event occurring alone.
The sum rule
the probability of the occurrence of one event or the other event, of two mutually exclusive events, is the sum of their individual probabilities (applied when considering two mutually exclusive outcomes that can come about by more than one pathway).
Dominant traits
traits that are inherited unchanged in a hybridization.
Recessive traits
traits that become latent, or disappear, in the offspring of a hybridization, but reappears in the progeny of the hybrid offspring
homozygous
a gene with two identical alleles on their homologous chromosomes
heterozygous
a gene with two different alleles on their homologous chromosomes
