what is happening in the transcription picture?

Half of the males are colorblind, dwarf and the other half colorblind, normal height.

Explanation:

The achondroplastic dwarf man with normal vision has a DdXY genotype. He marries a color-blind woman of normal height, so the hergenotype is ddX (c) X (c). All males will be colorblind as they inherit the X (c) chromosome from their mother. Half of them will be of normal height. So half of her boys will be colorblind and of normal height. To see how it works genetically, the cross is:

DdXY x ddX (c) X (c)

Your children have one of the four possible genotypes:

DdXX (c) (female, normal vision, colorblind carrier, dwarf)

DdX (c) Y (male, colorblind, dwarf)

ddXX (c) (woman, normal vision, color blindness carrier, normal height)

ddX (c) Y (male, colorblind, normal height)
