Independent assortment can take place only if genes are located on different homologous chromosomes .Mendel was lucky because 7 traits he studied were located on different homologous chromosomes .Bateson 1906 noted first deviation from Mendles law and it was explained by Morgan . Linked genes can't assort independently as they are transfered en block .

What concept is considered an exception to Mendel's law of independent assortment?
Gene linkage us considered an exception to Mendel's Law of Independent Assortment.
Which of Mendel's laws does Gene Linkage break?
Gene linkage breaks Mendel's law of independent assortment. This law states that alleles for different traits segregate independently during gamete formation. However, when genes are located close together on the same chromosome, they tend to be inherited together, violating the principle of independent assortment, as linked genes do not assort independently.
What does the theory of independent assortment say?
The theory of independent assortment, proposed by Gregor Mendel, states that the alleles for different genes segregate independently of one another during the formation of gametes. This means that the inheritance of one trait does not influence the inheritance of another trait, leading to a variety of possible genetic combinations in offspring. This principle applies to genes located on different chromosomes or those far apart on the same chromosome. However, genes that are close together on the same chromosome may be inherited together, a phenomenon known as genetic linkage.
Thomas hunt Morgan discovered that some genes violated the principle of independent assortment?
Yes, Thomas Hunt Morgan discovered that some genes violate the principle of independent assortment through his work with fruit flies. He found cases of genes being linked on the same chromosome and therefore inherited together more often than predicted by Mendel's laws. This discovery led to the development of the concept of genetic linkage.
What is the fourth law of Mendel?
The fourth law of Mendel states that genes can be linked, meaning that they are inherited together and do not follow the law of independent assortment. This law explains the phenomenon of genetic linkage and how certain genes tend to be inherited together due to their physical proximity on the same chromosome.
What concept is considered an exception to Mendel's law of independent assortment?
Gene linkage us considered an exception to Mendel's Law of Independent Assortment.
What is the exception to Mendel's law of independent assortment?
The exception to Mendel's law of independent assortment is when genes are located close together on the same chromosome and therefore tend to be inherited together, rather than independently assorting during meiosis. This is known as genetic linkage.
Which of Mendel's laws does Gene Linkage break?
Gene linkage breaks Mendel's law of independent assortment. This law states that alleles for different traits segregate independently during gamete formation. However, when genes are located close together on the same chromosome, they tend to be inherited together, violating the principle of independent assortment, as linked genes do not assort independently.
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 theory behind gene linkage?
Gene linkage is the tendency of genes located on the same chromosome to be inherited together. This is because genes that are physically close to each other on a chromosome have a lower chance of being separated during meiosis. The degree of linkage is measured by the recombination frequency, which is influenced by the distance between genes on a chromosome.

What is the result of two genes located on the same chromosome but they are far apart?
The fact that they consistently sort independently indicates that they are far apart on the chromosome.
Genes for two different traits that are located next to each other on the same chromosome would most likely be?
Inherited together if they are close enough, a phenomenon known as genetic linkage. This is because the genes are less likely to undergo independent assortment during meiosis due to their physical proximity on the chromosome.
Thomas hunt Morgan discovered that some genes violated the principle of independent assortment?
Yes, Thomas Hunt Morgan discovered that some genes violate the principle of independent assortment through his work with fruit flies. He found cases of genes being linked on the same chromosome and therefore inherited together more often than predicted by Mendel's laws. This discovery led to the development of the concept of genetic linkage.
Why does the law of independent assortment relates to crossing over and genetic linkage by?
This recombination of genes, called the crossing over of DNA, can cause alleles previously on the same chromosome to be separated and end up in different daughter cells. The farther the two alleles are apart, the greater the chance that a cross-over event may occur between them, and the greater the chance that the alleles are separated. - See more at: http://www.chacha.com/question/if-mendel's-law-of-independent-assortment-states-that-allele-pairs-separate-independently-of-each-other-during-meiosis.-how-does-this-law-relate-to-crossing-over-and-genetic-linkage#sthash.pJkZU4x9.dpuf
