Why do daughters inherit more genes from their fathers?

Daughters generally look like fathers, boys generally look like mothers, and mothers have more genes. Inheritance is a very complicated process. Many times, parents are good-looking, but the children born are not beautiful at all, and they only inherit their parents' defects.

Generally speaking, both boys and girls have more genetic mother components, because the genetic materials in a fertilized egg are sperm nucleus, egg nucleus and cytoplasm, and the latter two come from mothers, so there are more genetic mothers.

In fact, according to the genetic law, parents will each provide half of the genes to their children. It is difficult to determine who will inherit more genes, but the latest research believes that the mother's genes play a leading role in the development of the child's brain, while the father's genes have a greater impact on the child's mood and personality.

Characteristics of genetic genes:

1, stable. The molecular structure of genes is stable and not easy to change. The stability of the gene comes from the accurate self-replication of the gene, which is distributed to daughter cells through cell division or passed on to offspring through sex cells, thus ensuring the stability of the gene.

2. Determine the development of traits. The specific genetic information carried by genes is transcribed into messenger ribonucleic acid (mRNA) and translated into polypeptide chains on ribosomes, and the polypeptide chains are folded into specific protein. Some are structural proteins, and more are enzymes. Genes control every biochemical process of organisms by controlling the synthesis of enzymes, thus controlling the development of traits.

3. variability. Due to the influence of mutagenic factors inside and outside the cell, the gene will mutate. The result of mutation is the generation of alleles and multiple alleles. Because of this variability of genes, we can recognize the existence of genes, increase the diversity of organisms and provide more choices.
