TWO IDENTICAL TWIN BOYS HAD DIFFERENT FINGER PRINT. THIS PROVES THAT

  • A. finger print is a sex-linked character
  • B. the genotypes of the twins are similar
  • C. the phenotypes of the twins are similar
  • D. there are morphological variations ✓
  • E. there are physiological variation in the twins

 

The answer to the question is: D. there are morphological variations

The fact that two identical twin boys have different fingerprints proves that there are morphological variations between them. Even though identical twins share the same DNA and genetic makeup, certain external factors during fetal development can lead to differences in physical characteristics, such as fingerprints. Fingerprints are formed during fetal development through a complex interplay of genetic and environmental factors, and even slight variations in the womb environment can result in distinct patterns.

While identical twins may have very similar physical appearances due to their shared genetic material, they are not completely identical at the morphological level. This is why even though they share the same genotype, they can exhibit differences in traits like fingerprints, which are influenced by both genetic and environmental factors.
