The observable characteristics of an organism, produced by its genes and the environment, are called its
Correct answer: B. phenotype
- A. genotype
- B. phenotype
- C. karyotype
- D. pedigree
Explanation
Phenotype is what can be seen or measured, while genotype is the allele combination behind it. Two plants can look identical yet differ in genotype, which is exactly why a test cross is needed.

About Mendel's Laws of Inheritance
Mendelian inheritance explains how alleles separate into gametes and assort during reproduction, producing predictable genotype and phenotype ratios. Questions cover dominance, recessiveness, homozygous and heterozygous conditions, the laws of segregation and independent assortment, monohybrid and dihybrid crosses, test crosses and the limits caused by linked genes.
