Answer
The law that states that when any individual produces gametes, the copies of a gene separate so that each gamete receives only one copy. Either of the allies will be received by gametes..

Answer:
According to the law of segregation, each diploid individual has two alleles (copies) for a specific attribute. A diploid organism is created when each parent randomly assigns one allele to each of their kids.
Explanation:
- Mendel examined the genetics of pea plants and determined how traits like flower color, flower location, seed color, and seed shape are passed down through the generations.
- He referred to the trait present in the generation that was apparent (violet flowers) as the dominant trait, and the trait absent or lost (white flowers) as the recessive trait.
- The F1 generations of true-breeding pea plants with opposing features all displayed the dominant trait, while the F2 generations of same plants expressed the dominant and recessive traits in a 3:1 ratio, the researchers noted.
- There are three possible genotype combinations for the F2 generation of a monohybrid cross: homozygous dominant, heterozygous, or homozygous recessive. The law backs up Mendel's observed 3:1 phenotypic ratio because heterozygotes can result from two separate paths (getting one dominant and one recessive allele from each parent) and because heterozygotes and homozygous dominant individuals share the same phenotype.
