Which option shows all a LLELE combinations that can be used to represent a purebred animal
To represent a purebred animal, all possible LLELE combinations can be used. Here is an example:
1. LL - Homozygous dominant for a specific trait
2. ll - Homozygous recessive for a specific trait
3. LE - Heterozygous for a specific trait
4. EL - Heterozygous for a specific trait
In this representation, "L" represents the dominant allele, and "l" represents the recessive allele for a particular trait. When an animal has two copies of the same allele (LL or ll), it is considered purebred for that specific trait. When an animal has one copy of each allele (LE or EL), it is heterozygous for that trait.
