Worked Solution & Example Answer:The ALDH alleles differ in their A - HSC - SSCE Biology - Question 19 - 2021 - Paper 1
Step 1
C. effect on phenotype.
Answer
The ALDH alleles differ primarily in their effect on phenotype. This refers to how different alleles of the same gene can lead to variations in observable traits, such as enzyme activity or response to certain substances. It is important to recognize that while genome location and amino acid composition can influence function, the key distinguishing feature of alleles in terms of observable characteristics is their effect on phenotype.
