How do you explain the law of Independent Assortment?
The Law of Independent Assortment states that during a dihybrid cross (crossing of two pairs of traits), an assortment of each pair of traits is independent of the other. In other words, during gamete formation, one pair of trait segregates from another pair of traits independently.
How did Mendel derive the law of Independent Assortment?
Mendel performed dihybrid crosses in plants that were true-breeding for two traits. For example, a plant that had round seeds and yellow seed color was cross-pollinated with a plant that had wrinkled seeds and green seed color. In this cross, the traits for round seed shape (RR) and yellow seed color (YY) are dominant.
What is Mendel’s 1st and 2nd Law?
Conclusion. Mendel’s first law describes the segregation of the two copies of alleles of a particular gene into the gametes. Mendel’s second law describes the independent assortment of alleles of different genes from each other during the formation of gametes.
What is Mendel’s law?
Definition of Mendel’s law 1 : a principle in genetics: hereditary units occur in pairs that separate during gamete formation so that every gamete receives but one member of a pair. — called also law of segregation.
What is Mendel Second law of Independent Assortment?
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.
What best describes the law of independent assortment?
Introduction. The law of segregation lets us predict how a single feature associated with a single gene is inherited.
What are Mendel’s laws?
Definition. Mendel’s laws describe how the inheritance of characteristics occurs and how its expression is determined by genes.
What statement explains Mendel’s law of segregation?
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. The law of segregation ensures that a parent, with two copies of each gene, can pass on either allele.
What is Mendel’s second law of heredity?
Also known as Mendel’s second law of inheritance, the law of independent assortment states that a pair of trait segregates independently of another pair during gamete formation. As the individual heredity factors assort independently, different traits get equal opportunity to occur together.
