Symptoms of genetic defects in children

summary

Children will inherit many characteristics of their parents. For example, if both parents have double eyelids, the child will also have double eyelids, which is also determined by genes. If parents have some physical diseases, they will also pass them on to their children, so some parents are not suitable to have children. The symptoms of children with genetic problems are also very obvious, so genes have many characteristics, such as universality, randomness and non directionality. I would like to share with you my views on the symptoms of children's genetic defects.

Symptoms of genetic defects in children

1. Universality because there are many factors inducing gene mutation in nature, and it can also occur spontaneously, so gene mutation is common in the biological world.

2. Randomness randomness refers to the time of gene mutation, mutation individuals, mutation genes, etc., which are all random. Numerous mutations found in higher plants indicate the randomness of gene mutation. Generally speaking, in the ontogeny of organisms, the later the gene mutation occurs, the less mutation the organism shows.

3. The non directivity of non directional gene mutation is that one gene can mutate in different directions and produce more than one allele. For example, the gray gene that controls the color of mouse hair can mutate into either the yellow gene or the black gene, and there is no clear causal relationship between the direction of gene mutation and the environment.

matters needing attention

Generally, gene mutation will have some adverse effects, such as being eliminated or dying. Only a few gene mutations are favorable, which may enhance the adaptability of the species.
