Answer:
Offspring with genotype "FF" are short fur.
Offspring with genotype "Ff" are some short fur some log fur.
Offspring with genotype "ff" are long fur.
Explanation:
The genotype of short fur female is "Ff"
The genotype of short fur male is "Ff"
This means that allele for short fur is "F" and the allele for long allele is "f".
Also, short fur allele "F" is dominant over long fur allele "f"
If short fur female is "Ff" is crossed with short fur male is "Ff", the following offspring are produced.
Ff * Ff
FF, Ff, Ff, ff
Offspring with genotype "FF" are short fur.
Offspring with genotype "Ff" are some short fur some log fur.
Offspring with genotype "ff" are long fur.
