which was largely unnoticed until ____, when Mendel's laws of inheritance were independently rediscovered by three scientist.

the organism of the dominant phenotype, but unknown genotype, is crossed to a homozygous recessive individual

It shows the genotypes and phenotypes from the recombination of gametes during fertilization.

Mendel's first three postulate

  During the formation of gametes, the paired unit factors separate or segregate randomly so that each gamete receives one or the other.

  When two unlike factors responsible for a single character are present in a single individual, one unit factor is dominant to the other, which is said to be recessive.

  Genetic characters are controlled by unit factors that exists in pairs in individual organisms.

The simplest cross involving one pair of contrasting traits.

different alleles constituting the genotype

identical alleles constituting the genotype
