If a cat with long black hair (Llbb) is crossed with a cat with short hair (llbb). What is the possibility that an offspring will have long black hair or short hair?

50% long black hair and 50% short hair

Explanation:

Attatched is a screenshot of a punnett square that shows the possibilities of the offspring having long or short hair. In short, the genetics of long black hair only need one big "L", while the genetics of short hair need to have 2 short "l"s. So when we draw the punnett square and combine the genetics, we get 50% have Llbb, and 50% have llbb
