In cats, long hair is recessive to short hair. a true breeding (homozygous) short-haired male is mated to a long-haired female. what are the genotypic and phenotypic ratios of their children?

punnet square 1:

homozygous (LL: normal) or (ll: affected) homo meaning same

recessive (ll)

Square would look like:

Ll, Ll, Ll, Ll= 100% of the cats will be carrier of short hair genes.

punnet square 2: if the male was affected he would also have ll as his traits, which would make 100% of their offspring affected mutantsmeaning they would all have recessive traits.

Since you did not say that the male was affected and that he was a true breeding short haired male, then punnet square 1 is what you need to look at. I put square 2 up so that you could see what the ratio would be if both male and female cats had (ll) alleles.

Hopefully this helped and good luck. 

cuz he is really really short, assuming an unorthodox and inherently unlucky configuration of elevator buttons…
