The father’s color weakness is usually not inherited to the child, color weakness inheritance is mainly through the sex chromosome to inherit, the sex chromosome mainly has two, one is X chromosome, the other is Y chromosome, color weakness gene is mainly through the X chromosome inheritance. If the child’s sex chromosome is XY, it is a boy, and two X’s is a girl. Since the father’s chromosome is one X and one Y, the gene for chromosomal weakness is on the X chromosome, and the sex chromosome inherited from the father to the child is mainly the Y chromosome, so the father’s chromosomal weakness X chromosome will not be inherited to the child, but only the Y chromosome will be inherited to the child. The X chromosome of the child is inherited from the mother, so if the mother does not have chromosomal weakness, the probability of the next generation of children having chromosomal weakness is low, and it usually depends on whether the mother carries the chromosomal weakness gene. If the mother carries the gene, it may be passed on to the child, but if she does not, the next generation of children will not have chromosomal defects.
