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.
