Question 32 The process resulting in an incorrect number of chromosomes is called ____. trisomy monozygosity nondisjunction autosomy Question 33 What are different variations of the same gene, such as red and white petal color of a flower? Question 34 What occurs if a cell fails the G1 checkpoint and the cell cycle is halted? The cell can undergo apoptosis. DNA can be repaired. Benign tumors can start to form. All of the above are correct. The cell can undergo apoptosis and DNA can be repaired
Gene Interactions
When the expression of a single trait is influenced by two or more different non-allelic genes, it is termed as genetic interaction. According to Mendel's law of inheritance, each gene functions in its own way and does not depend on the function of another gene, i.e., a single gene controls each of seven characteristics considered, but the complex contribution of many different genes determine many traits of an organism.
Gene Expression
Gene expression is a process by which the instructions present in deoxyribonucleic acid (DNA) are converted into useful molecules such as proteins, and functional messenger ribonucleic (mRNA) molecules in the case of non-protein-coding genes.
