Explain the law of independent assortment.?

Question

Answer

It states that the gene of different character located in different pair of chromosomes are independent of one another in their segregation during gamete formation . mendalian recombinations only due to independent assortment . this principle was proved using dihybrid cross and phenotypic ratio 9:3:3:1

Answer

Hey here's ur answer...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.

Answer

What is Independent Assortment for dummies?

A dominant allele produces the same phenotype in heterozygotes and in homozygotes. Independent assortment: Alleles on different chromosomes are distributed randomly to individual gametes.

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 is the law of dominance?

Scientific definitions for mendel's law

Mendel's third law (also called the law of dominance) states that one of the factors for a pair of inherited traits will be dominant and the other recessive, unless both factors are recessive.

Answer

The Law of Independent Assortment

The law of independent assortment is a fundamental principle in genetics that describes how different genes segregate and assort independently during the formation of gametes. This law was first proposed by Gregor Mendel, the father of modern genetics, based on his experiments with pea plants.

Understanding the Law

The law of independent assortment states that the alleles for different traits segregate, or separate, independently of one another during the formation of gametes. In other words, the inheritance of one trait does not influence the inheritance of another trait. This principle applies when genes are located on different chromosomes or when they are located far apart on the same chromosome.

Mendel's Experiment

Mendel conducted experiments on pea plants to study the inheritance of different traits, such as flower color and seed shape. He observed that when he crossed plants with different traits, such as a plant with yellow seeds and a plant with green seeds, the offspring always had yellow seeds. However, when he further bred these yellow-seeded plants, the next generation exhibited a 3:1 ratio of yellow to green seeds.

Monohybrid Crosses

Mendel's monohybrid crosses involved the study of a single trait. For example, he crossed pea plants with yellow seeds (genotype YY) and pea plants with green seeds (genotype yy). According to the law of independent assortment, the alleles for seed color segregate independently during gamete formation. Therefore, the possible combinations of alleles in the gametes are Y and y. When these gametes combine, they produce offspring with the genotypes Yy, which results in yellow seeds.

Dihybrid Crosses

Mendel also conducted dihybrid crosses to study the inheritance of two different traits simultaneously. For instance, he crossed pea plants with yellow, round seeds (genotype YYRR) and pea plants with green, wrinkled seeds (genotype yyrr). According to the law of independent assortment, the alleles for seed color and seed shape segregate independently during gamete formation. Hence, the possible combinations of alleles in the gametes are YR, Yr, yR, and yr. When these gametes combine, they produce offspring with various genotypes and phenotypes, including yellow-round, yellow-wrinkled, green-round, and green-wrinkled seeds.

Conclusion

In summary, the law of independent assortment describes how genes separate independently during the formation of gametes. This principle allows for the creation of unique combinations of traits in offspring, contributing to genetic diversity. Mendel's experiments with pea plants provided evidence for the law of independent assortment and laid the foundation for our understanding of inheritance patterns.
