I can't draw a Punnett square on this site, but red green colorblind is recessive and carried on the X chromosome. So, if a male child receives this gene from his mother, then he will be colorblind (red green). If a female child receives this gene from her mother, she is a carrier, but not affected. If a female child receives this gene from her father, she will be a carrier. If a female receives this gene from her father and from a carrier mother, she will be colorblind.
