In guinea pigs, short fur (S) is dominant to long fur (s). Two heterozygous guinea pigs (Ss) mate. Complete the Punnett square and then list the percentages of the
expected genotypes for their offspring.

Explanation:

A way I like to remember heterozygous is by remembering that the other word for heterozygous because wont let me say it apparently. The same gender liking each other, so (word) is same, hetero is different.

each square would have 25% each because 100%÷4=25.

Dominant one is like mixing black and blue together,the black is gonna give a dark effect to blue so black is dominant.

Blue is recessive.

if someone had the list of traits you provided
