|
|
principle that during the formation of gametes two alleles for the genes separate so that half the the gametes carry on allele
|
|
|
the principle that allele pairs for different genes separate independently in meiosis, so the inheritance of one trait generally does not influence the inheritance of another trait
|
|
|
the principle that a trait is determined by instructions on one gene only.
|
|
|
None of the above

Detailed explanation-1: -Mendel’s law of segregation states that: “During the formation of gamete, each gene separates from each other so that each gamete carries only one allele for each gene.” Law of segregation is the second law of inheritance.
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: -Gregor Mendel’s law of segregation states that the two alleles for each trait segregate, or separate, during the formation of gametes, and that during the formation of new zygotes, the alleles will combine at random with other alleles.
Detailed explanation-4: -Although Mendel’s principle of independent assortment states that alleles of different genes will segregate independently into gametes, in reality, this is not always the case. Sometimes, alleles of certain genes are inherited together, and they do not appear to undergo independent assortment at all.
