Answer:
It is multicellular.
that's my logical answer .
Explanation:
If the father had the gene BB (purebred & not carrying colourblind allele), then the answer will be a). All of their children will have normal vision with half of them carrying the colourblind allele.
If the father had the gene Bb (hydrid & carrying colourblind allele), then the answer will be d). 3/4 of their children would have normal vision whilst the last quarter would have colourblind males. This is due to them having to receive one colourblind allele from their mother on the X chromosome & one colourblind allele from their father on the Y chromosome.
