Summary Introduction

To determine: The probabilities that the first child will be a color-blind boy.

Introduction: Red or green color blindness is carried from mother to son at the 23rd chromosome, which is identified as the sex chromosome as it further illustrates as sex chromosome.

Summary Introduction

To determine: The proportion that can be estimated to be color-blind of any girl.

Introduction: A color-blind boy cannot inherit a color-blind ‘gene’ from the father, yet his father is color blind as his father can pass an X chromosome to the daughters.

d.

Summary Introduction

To determine: The proportion that can be expected to have a normal color vision of all the children.

Introduction: The color blind 'gene' is conducted on one of the X chromosomes. As men possess only one X chromosome, and if his X chromosome transfers the color blind 'gene' that is 'X,' he will be color blind XY.
