Sagot :
Colorblindness is a congenital illness that is handed down from parents. The X-chromosome contains the gene for red-green colorblindness.
If the colorblind gene is present, one out of every three cone cells does not form or becomes less sensitive to light.
-It is a recessive X-linked illness. Colorblind genes must be present on both X chromosomes in females (XX) in order to manifest phenotypically.
This indicates that if colorblind genes are present on both X-chromosomes, the female will be colorblind. If a woman carries only one color-blind gene, she is referred to be a "carrier," but she will not be colorblind.
-Males (XY) will be colorblind if the gene is exclusively found on his X chromosome. As a result, even if his father is colorblind, a colorblind boy cannot inherit a colorblind gene from him since his father can only pass on an X chromosome to his daughters.
As can be seen, each kid has a 50% probability of being colorblind. Each daughter is 50% likely to be colorblind and 50% likely to be a carrier. The tough aspect about utilizing this table is when Mom isn't colorblind.
