| Direction Read the following and answer the questions from given below |
| Genes are segments of Deoxyribonucleic Acid (DNA) that contains the code for a specific protein that functions in one or more types of cells in the body. Chromosomes are structures within cells that contain a person's genes. Genes are passed down the generations in a particular manner and we receive roughly half of our genetic material from each parent. Chromosomes describe and determine gender and any change in them causes chromosomal abnormalities. |
| (iii) If the genes are located in a chromosome as |
| A-B-C-D-E-O-T. |
| Which of the gene pairs will have least probability of being not inherited together? |
A) C and D
B) A and T
C) A and B
D) O and T
Correct Answer: B
Solution :
[b] Longer is the distance, lesser will be the probability of the two genes being inherited together as there will be a greater chance of recombination. Thus, A and T would not inherit together.
