Journey Harding · Answer 1

The offspring of long fins will be heterozygous dominant and of short fins will be homozygous recessive.

Explanation: Heterozygous long finned fish will have a genotype of Ll. Homozygous short finned fish will have a genotype of ll. The possible genotypes of their offsprings will be: Ll * ll Ll, Ll, ll, ll. The probability of short-finned fish will be 1/2 and the probability of long finned fish will also 1/2. So the short-finned offspring will be homozygous recessive and long finned will be heterozygous dominant.

Lena Kerr · Answer 2

A certain species of fish can have either long or short fins. The allele for long fins is dominant over the allele for short fins. A heterozygous, long-finned fish is crossed with a homozygous, short-finned fish. Of the offspring, 50% will have long fins and be heterozygous, and 50% will have short fins and be homozygous.
