TAMU bio 111 lab exam 2 review (2023/2024) already passed What is the difference between the coding and non-coding region? Coding region: comprised of genes that encode proteins (instructions that determine traits) and makes up 1-2% of human DNA. • Noncoding region: makes up 98-99% of human DNA, contains STRs and is responsible for regulatory functions such as gene transcription. 
What are STRs? Short-tandem repeats (STRs) are unique repeating patterns of the same nucleotide sequence. They can...

This assignment and unit are overall awarded a distinction. This is Assignment C of Unit 11 and will talk about human inheritance and predicting genetic traits. In this assignment I have given examples of Mendles pea plants, explained F1 and F2 generation, and carried out and investigate Dihybrid and monohybrid inheritance in mazes have concluded my findings using chi-squared and conclusions. I have used drosophila flies, cystic fibrosis, hemophilia, blood group in this assignment as examples.
