Answer:

 According to the question, the genotype of the Cat 2 will be heterozygous for both the traits: LlWw

The phenotype will show the characteristics of the dominant alleles i.e long hair and white coat.

Explanation:

Let's complete the Punnet Square first:

           LW            Lw           IW       Iw

LW  LLWW        LLWw      LlWW    LlWw

Lw  LLWw         LLww       LlWw     Llww

lW   LlWW          LlWw      llWW     llWw

lw    LlWw          Llww        llWw     llww

A punnet square can be described as a diagram which is made to predict the outcomes of a cross.

A cross in which only one trait is under study is a monohybrid cross.

A cross in which two traits are being studies at a time is know as a dihybrid cross. The question above shows a dihybrid cross.
