2. How are single-gene traits useful in studying human genetics?
Single-gene traits are useful in studying human genetics because they are controlled by a single gene, making them easier to study and analyze than complex traits that are influenced by multiple genes and environmental factors.
By studying single-gene traits, scientists can determine the mode of inheritance, whether it be dominant, recessive, or X-linked, and use that information to make predictions about the likelihood of a trait being passed on to future generations. Single-gene traits can also be used to trace patterns of inheritance within families and populations, and to identify carriers of genetic diseases, which is particularly important for genetic counseling and family planning.

Explain how meiosis gives rise to genetic variation in gametes (2)
Meiosis is the process of cell division that occurs in the formation of gametes or sex cells. During meiosis, there are two rounds of cell division that result in the production of four genetically unique daughter cells or gametes.
This genetic variation is caused by two key processes: crossing over and independent assortment. Crossing over occurs during the first round of meiosis when homologous chromosomes exchange genetic material. This process results in new combinations of alleles, the different versions of genes, on each chromosome. As a result, gametes produced from meiosis have a different combination of genetic information than the original parent cell.
Independent assortment occurs during the second round of meiosis when the homologous chromosomes separate and migrates to opposite poles of the cell randomly. This process produces a variety of different combinations of chromosomes in the resulting gametes. The likelihood of different combinations of chromosomes in gametes is increased by a large number of chromosomes present in the parent cell.
Overall, the combination of crossing over and independent assortment in meiosis results in a high level of genetic variation in gametes, which is important for the survival and evolution of a species.

What is used during step 6 (to oxidize glyceraldehyde 3-phosphate) ?
Nicotinamide adenine dinucleotide (NAD+) as the oxidizing agent is used during step 6 (to oxidize glyceraldehyde 3-phosphate).
The coenzyme nicotinamide adenine dinucleotide (NAD) is crucial for metabolism. NAD, a dinucleotide that is present in all living cells, is so named because it is made up of two nucleotides that are connected by their phosphate groups. Adenine and nicotinamide are found in different nucleotides. NAD occurs in two states: an oxidised state known as NAD+ and a reduced state known as NADH (H for hydrogen).
NAD transports electrons from one redox reaction to another during metabolic processes. As a result, cells have the cofactor in two different forms: By absorbing electrons from other molecules and getting reduced, NAD+ acts as an oxidising agent. When H+ is added, this process produces NADH, which may be utilised as a reducing agent to give electrons. The principal use of NAD is in these electron transfer processes.

The liver disease that causes portal hypertension with ascites:
Cirrhosis is a common liver disease that can cause portal hypertension and ascites, but other liver diseases may also lead to these symptoms. Seeking medical attention is crucial for an accurate diagnosis and appropriate treatment.
One of the most common liver diseases that can cause portal hypertension and ascites is cirrhosis. Cirrhosis is a progressive and irreversible liver disease that occurs when the liver becomes damaged and scarred over time, usually due to chronic alcohol abuse or hepatitis B or C.
As cirrhosis progresses, scar tissue replaces healthy liver tissue, leading to increased pressure in the portal vein that carries blood from the digestive system to the liver. This increased pressure, called portal hypertension, can cause fluid to accumulate in the abdomen, leading to ascites.
Other symptoms of cirrhosis may include jaundice, fatigue, itching, and mental confusion. Treatment for cirrhosis may involve lifestyle changes such as abstaining from alcohol, medications to manage symptoms and complications, and in severe cases, liver transplantation.
