The new embryonic structures result from Some genetic phenomena that cause the emergence of new strains within the same species with characteristics different from the parents, and the contents of the site will address through the following article the topic of what are the reasons that cause the emergence of new embryonic structures, highlighting the most important factors related to the topic.

The new embryonic structures result from

The new embryonic structures result from my phenomenon Genetic crossing over (so-called mutations) and free distributionHeredity is defined as the transmission of the physical traits of two parents (father and mother) to the children through the transmission of the halves of the genetic codes (chromosomes) from the father, which converge from the halves of the genetic codes coming from the mother to form together a pair that determines a trait of the sons, which is often similar to the trait Parents according to the dominant trait, and in some cases, strains appear that carry traits different from those of the parents, and this is called the production of new embryonic structures.

The phenomenon of genetic crossing over

The phenomenon of genetic crossing is defined as a change that occurs in the DNA sequence due to some errors that may result when copying DNA, or as a result of various environmental factors, and in some cases cells can recognize the damage that may cause mutation, and repair it before the mutation occurs, and in all cases Conditions Mutations contribute to genetic variation within species, and the most important reasons that may lead to the phenomenon of genetic crossing are:[1]

  • Change in the structure of processed proteins, for better or worse.
  • Errors that occur during DNA replication.
  • Exposure to various environmental factors such as ultraviolet rays, radioactive substances, and sometimes smoking.

free distribution phenomenon

It is the second law of Mandel’s genetic laws, and it indicates that separate genes for traits are transmitted from parents to children independently of each other, that is, half of the genetic code for a particular trait is transmitted from the father (father and mother) to the children independent of half of the genetic code for a trait Others, and this may contribute in one way or another to the emergence of new strains.

This concludes the article on the topic The new embryonic structures result from The phenomena of genetic crossing and free distribution to produce new strains that carry different genetic characteristics from those of the parents.
