Answer:
the genetics and DNA
Explanation:
Differences in hair texture mainly comes from our genetic, but more specific from our DNA. We could get the trait from either our mother or father or both. It depends on the shape of the hair follicles in our head. The genetic factor plays the major role in determining the hair texture. For example, if the child comes with recessive genes from the parents then the outcome could be a complete opposite outcome (parents with curly hair could have kids with straight hair). At the end it depends on how strong the genes are.
The differences in traits such as hair texture are determined by differences in the SEQUENCE of nucleotides in DNA.
The deoxyribonucleic acid (DNA) is a double helix molecule composed of two long chains of nucleotides.
During gene transcription, a fragment of the DNA sequence referred to as a 'gene' is used as template to create a messenger RNA, which is then used as template to create a protein by a process known as translation.
The order of the nucleotides in a gene determines the sequences of the proteins obtained from transcription and further translation.
The phenotypic traits are largely determined by both structural and enzymatic proteins.
In conclusion, the differences in traits such as hair texture are determined by differences in the SEQUENCE of nucleotides in DNA.
