How did the results of Mendel's dihybrid crosses lead him to formulate the law of independent assortment?
When crosses were made taking into account two dominant charater in a parent with
another parent having racessive genes for those characters, in F1 generation all plants had dominant characters but in F2 generation, on self-pollination, the segregation in both the characters were observed independent of each other.

What was the purpose of mendels expirements with dihybrid crossing?
Mendel's experiments with dihybrid crossing were aimed at studying the inheritance patterns of two different traits (such as seed color and seed shape) simultaneously. By observing the outcomes of crossing pea plants with different combinations of traits, Mendel was able to establish the principles of independent assortment and gene linkage.
When two traits are on different chromosomes how are they inherited?
When two traits are located on different chromosomes, they assort independently during meiosis. This means that the inheritance of one trait does not influence the inheritance of the other trait, resulting in a random assortment of genetic information. This independent assortment allows for a variety of genetic combinations in the offspring.
What are the three part of mendels hypothesis?
Mendel's three parts of his hypothesis are: the principle of segregation (alleles separate during gamete formation), the principle of independent assortment (traits are inherited independently of each other), and the principle of dominance (one allele is dominant over another).
Is it true that Mendels principles apply not to just to pea plants but to other organism as well?
Yes, Mendel's principles of inheritance, such as the law of segregation and the law of independent assortment, apply to many other organisms beyond pea plants. These principles have been found to hold true in various animals, plants, and even humans, demonstrating their widespread relevance in genetics.
A major deviation from mendels law occurs because of?
A major deviation from Mendel's laws, specifically the law of independent assortment, can occur due to genetic linkage. This is when genes located close together on the same chromosome are inherited together more often than expected. As a result, they do not assort independently as predicted by Mendel.

What are mendels laws?
law of segregation, independent assortment, and dominance.
Which of mendels principles would apply to mating two organisms that have two different alleles for three different traits?
The principle of segregation and the principle of independent assortment would apply. The principle of segregation states that each parent contributes one allele for each trait, and the principle of independent assortment states that alleles for different traits are inherited independently of each other.
How Is Mendels law are obseved in meiosis?
Mendel's laws of segregation and independent assortment are observed in meiosis through the separation of alleles during the formation of gametes. Segregation occurs during anaphase I of meiosis, where homologous chromosomes separate and each gamete receives one copy of each gene. Independent assortment takes place during metaphase I, where homologous pairs line up randomly along the metaphase plate, resulting in a randomized distribution of alleles into gametes.
When two traits are on different chromosomes how are they inherited?
When two traits are located on different chromosomes, they assort independently during meiosis. This means that the inheritance of one trait does not influence the inheritance of the other trait, resulting in a random assortment of genetic information.

What are Mendels 3 princples?
Mendel's three principles, derived from his experiments with pea plants, are the Law of Segregation, the Law of Independent Assortment, and the Law of Dominance. The Law of Segregation states that allele pairs separate during gamete formation, ensuring offspring receive one allele from each parent. The Law of Independent Assortment asserts that genes for different traits are inherited independently of one another. Lastly, the Law of Dominance indicates that some alleles are dominant and will mask the expression of recessive alleles in heterozygous individuals.
A major deviation from mendels law occurs because of?
A major deviation from Mendel's laws, specifically the law of independent assortment, can occur due to genetic linkage. This is when genes located close together on the same chromosome are inherited together more often than expected. As a result, they do not assort independently as predicted by Mendel.
What is the law of independent association?
Examples of Law of Independent AssortmentThe law of independent assortment applies well to most plants and animals, but only to those genes which occur on non-homologous autosomal chromosomes. Here, following dihybrid crosses of guinea pigs and Drosophila can be considered as the examples for law of independent assortment in animals.1. When a black short haired guinea pig (BB SS, the black colour and short hairs dominate over brown colour and longhairs respectively) and a brown, long-haired- guinea pig (bb ss) are mated, the BB SS individuals produce gametes all of which are BS. The bb ss guinea pigs produce only bs gametes. Each gamete contains one and only one of each kind of gene. The union of BS gametes and bs gametes yields F1 heterozygous, black, short haired individuals with the genotype of Bb Ss.However, when two of the F1 individuals are mated each produces four kinds of gametes in equal numbers-BS, Bs, bS, bs. These gametes unite to produce 16 combinations in F1 in the phenotypic ratio of 9 black, short haired: 3 black, long haired: 3 brown, short haired: 1 brown, long haired or 9 : 3 : 3 : I. The results of this cross have been represented by following diagram.F2 Eggs Sperms 3-Black, Short Black, Short Black, Short Black, Short Black, Short Black, Short 3-Black, Long Black, Long Black, Long Black, Long Black, Long Black, Long 3-Brown, Short Brown, Short Brown, Short Brown, Short Brown, Short Brown, Short 1-Brown, Long Brown, Long Brown, Long Brown, Long Brown, Long Brown, LongThe results of this cross clearly show that the segregation of the B-b genes is independent of the segregation of the S-s genes.http://www.microbiologyprocedure.com/genetics/dihybrid-crosses-and-mendels-law-of-independent-assortment/examples-of-law-of-independent-assortment-in-animals.htm
