|
|
|
states that factors for different characteristics are distributed to gametes independently.
|
|
|
Each organism contains two factors for each trait; factors segregate in the formation of gametes. When two gametes combine during fertilization, the offspring have two factors controlling a specific trait.
|
|
|
a form of intermediate inheritance in which one allele for a specific trait is not completely dominant over the other.
|
|
|
is the likelihood that a specific event will occur or is the likely outcome a given event will occur from random chance

Detailed explanation-1: -Answer: It is also called the first law of inheritance. The law of segregation states that: ‘’The two copies of each genetic factor segregate during the development of gametes, to ensure that each parent’s offspring attains one factor. ‘’
Detailed explanation-2: -When an organism makes gametes, each gamete receives just one gene copy, which is selected randomly. This is known as the law of segregation. A Punnett square can be used to predict genotypes (allele combinations) and phenotypes (observable traits) of offspring from genetic crosses.
Detailed explanation-3: -The Principle of Segregation describes how pairs of gene variants are separated into reproductive cells. The segregation of gene variants, called alleles, and their corresponding traits was first observed by Gregor Mendel in 1865. Mendel was studying genetics by performing mating crosses in pea plants.
Detailed explanation-4: -Law of Segregation: Each hereditary characteristic is controlled by two alleles which separate into different gametes. Law of Independent Assortment: The separation of alleles for one gene is independent to allele separation for another gene.
