Explanation:
Long/short spines is a trait controlled by a single gene.
A homozygous dominant plant (LL) has long spines, so the dominant allele is L which determines long spines.
The cross between the LL parent and another cactus plant gives 100% cactus with long spines (either LL or Ll).
The genotype of the second parent plant cannot be determined from this experiment. Regardless of the genotype of the second plant (LL, Ll or ll), all cactus babies resulting from this cross will always have at least one dominant L allele from the first parent plant, giving all cactus babies with long spines.
Long/short spines are a trait exploited by a single gene.
A Wild-type dominant plant (LL) has extended spines, so the dominant allele is L which confines long spines.
The Cross between the LL parent and another cactus manufacturer offers 100% cactus with long spines (either LL or Ll).
The genotype of the two-parent plant cannot be unhesitating from this experiment. However, of the genotype of the double plant (LL, Ll, or ll), all cactus babies resulting from this will invariably have at least one dominant L allele from the first parent plant, giving all cactus with prolonged spines.
