Shane and Blane are monozygotic twins.However,people seldom get the two brothers mixed up because Blane is almost two inches shorter than Shane.What can you conclude based on this evidence
A) Because the brothers display different phenotypes, they must also have different underlying genotypes.
B) Even though both brothers share the same genotype, they display different phenotypes.
C) Even though both brothers display the same phenotype, they have different genotypes.
D) Blane is heterozygous for the "tallness" trait, and Shane is homozygous for the "tallness" trait.
Phenotypes
The visible attributes or qualities of an organism that arise from the interplay between its genetic makeup and environmental factors.
Genotypes
The genetic makeup of an organism, consisting of all the inherited alleles that influence traits and characteristics.
Monozygotic Twins
Identical twins resulting from a single fertilized egg splitting into two, sharing the exact genetic makeup.
- Explain how genetic and environmental factors contribute to variations in physical and psychological traits among individuals, including twin studies.
- Detail the rudimentary aspects of genetics, particularly the features of genotype and phenotype, and the involvement of chromosomes and genes in hereditary transmission.
