Introduction:
The study of heredity is called genetics. Gregor Mendel was a mathematician whose experiments with garden pea plants gave insight into the inheritance of traits. He developed the law of segregation and law of independent assortment.

Answer to Problem 24A
Correct answer :
The correct answer is option B. gene linkage
Explanation of Solution
Explanation/justification for the correct answer:
OptionB. gene linkage −Mendel developed the law of independent assortment which states that a random distribution of alleles occur during gamete formation. Genes on separate chromosomes sort independently during meiosis.
Gens that are located close to each other on the same chromosome are said to be linked. Many experiments have confirmed that linked genes travel together during meiosis. The linkage of genes on a chromosome is an exception to the law of independent assortment because linked genes do not segregate independently.
Hence, this is the correct option.
Explanation for incorrect answer:
Option A. crossing over- Crossing over is the process by which the genetic material between non sister chromatids of homologous chromosomes is exchanged. It results in new combinations of genes in the daughter cells.It is not an exception to law of independent assortment.
Hence, this is not the correct option.
Option C. polyploidy- Polyploidy cells have one or more extra sets of chromosomes. For example there could be a triploid organism with 3n number of chromosomes. Polyploidy is rare in animals except in earthworms and goldfish. It is lethal in humans but is very common in flowering plants. It follows law of independent assortment. Hence, this is not the correct option.
Option D. law of segregation- Mendel’slaw of segregation states that the two alleles for each trait separate during meiosis. The two alleles unite during fertilization. This law follows the law of independent assortment as the two alleles for a trait are distributed randomly during gamete formation. Hence, this is not the correct option.

The lipid is composed of one glycerol molecule connected to two fatty acid tails. One fatty acid is 12 carbons long and the other fatty acid is 18 carbons long in the figure below. Use the information below to determine how much ATP will be produced from the glycerol part of the lipid. Then, in part B, determine how much ATP is produced from the 2 fatty acids of the lipid. Finally put the NADH and ATP yields together from the glycerol and fatty acids (part A and B) to determine your total number of ATP produced per lipid.
