|
|
|
the principle that assorted alleles are independant
|
|
|
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
|
|
|
principle that independent organisms can’t assort their genes to change their genetic material, meaning an organism is born only with the traits it inherits.
|

|
None of the above

Detailed explanation-1: -Mendel’s law of independent assortment states that the alleles of two (or more) different genes get sorted into gametes independently of one another. In other words, the allele a gamete receives for one gene does not influence the allele received for another gene.
Detailed explanation-2: -The Principle of Independent Assortment describes how different genes independently separate from one another when reproductive cells develop. Independent assortment of genes and their corresponding traits was first observed by Gregor Mendel in 1865 during his studies of genetics in pea plants.
Detailed explanation-3: -The Law of Independent Assortment states that different genes and their alleles are inherited independently within sexually reproducing organisms. During meiosis, chromosomes are separated into multiple gametes. Genes linked on a chromosome can rearrange themselves through the process of crossing-over.
Detailed explanation-4: -The law of segregation is the second law of heredity. This law explains that the pair of alleles separates from each other during the cell division of meiosis (formation of gametes), so there is only one allele in each gamete. In a single-hybrid cross, both alleles are expressed in the F2 generation without mixing.
Detailed explanation-5: -Independent assortment states that an allele for each gene is passed on independently from alleles of other genes. Likewise, segregation states that the two alleles for each gene are separated and only one is passed on.
