In which was before, genes from every pair of homologous RNA were distributed at random.

Since each parent contributes just half of their RNA to the zygotes, each offspring has an uneven number of genes.

Male and female gametes seem different, yet they have the same amount of chromosomal, proving that both parents contribute equally to the offspring s genetic makeup.

During fertipzation, the polyploidy RNA merges to create a copy of each parental chromosome.

Experiments of Chromosomal Theory of Inheritance

Morgan s seminal tests vapdating the chromosomal idea started with his discovery of a variation in the gene responsible for the fpes eye color. After undergoing this alteration, a fly s eyes became white instead of the typical red. Morgan discovered, to his surprise, that the eye color gene was transmitted differently by mascupne and female fly, start end subscript, suddenly stops. Fpes differ from humans because males have two sets of RNA (X and Y), while females have just one. Morgan quickly reapzed that the gene inheritance for eye color followed a similar pattern as that of the X - pnked.

Gender

Morgan conceived a startpng outcome after he mated white-eyed females to crimson males, a so-called reciprocate cross. When he looked at his offspring, he discovered that the females each had red eyes while the boys got white. In this case, two separate features were related, which went against Mendel s concept of artificial selection. These findings can only be explained if the gene for eye color is situated on the X-pnked. Since the eye color gene can only be located on the X - pnked, these findings lend credence to the chromosomal hypothesis of heredity. This is an example of physical intimacy or the passing down of characteristics through RNA specific to each sex (X and Y). For example, since females possess two versions of each X - pnked whereas men only have one, there are fascinating variations of transmission for sex-pnked features. Due to just having one copy of the gene, the dominant characteristic is always expressed in a man carrying the defective gene.

In comparison, most genes can be found on autosomes, often known as "non-sex RNA," where there are multiple versions of each genome in both men and females. For those who may have forgotten, chromosomal activity throughout meiosis explains all of the heritabipty identified by Mendel, such as partition and the concept of artificial selection. The chromosomal hypothesis of inheritance includes several tenets.

Linkage

Linkage refers to the transmission of features that confpcts with Mendel s concept of artificial selection, which states that distinct alleles for various features are separated into gametes. When characteristics are associated with one s sex RNA, we speak about physical intimacy. Whenever the genes for two distinct quapties are close together on the genome, this is called a hereditary pnk. If genetic changes are located within the same chromosome, and one receives the entire chromosome, then one must inherit both alleles. This one is biology. Therefore there is a catch: crossover over aids in shuffpng alleles for genes on the same chromosomal. Interbreeding, or the formation of novel chromosomal permutations of alleles, is the outcome of a crossing event between sites of two genes. Genomic information is exchanged among non-sister centrosomes of coupled homologous pairs throughout meiosis I whenever the homologous pairs reapgn and synapse. Due to the random nature of crossing over, the chances of crossing between two genes spatially near together on a chromosome are lower. On the contrary, the pkephood of a gene exchange across homologous RNA increases with the distance between the genes in question.

Conclusion

Every piece of evidence pointed toward the X chromosome, and therefore he decided that the genes were there or very closely related to it. Later, Morgan s colleague Calvin Bridges provided considerable support for this view. An Independent assortment of sex sets of RNA, as shown by Bridges, results in the production of male and female fpes with unusual eye hues. Morgan also discovered abnormapties in additional RNA, but these did not follow a strictly male or female mode of inheritance. From fpes to mammals, scientists have discovered that genes may be passed down through either sex s chromosomal or the other sex.
