In a population the homozygous dominant individual make up 70% of the population while heterozygous ones made up 21% and recessive made up 9%. What are the frequencies of the A and a alleles?
Answers
There are two alleles in a population that influence a specific attribute. Using the letters "A" for the dominant allele and "a" for the recessive allele. A allele frequency is 0.7, whereas frequency of allele is 0.09.
The frequency of the A allele is 0.7, or 70%, since homozygous dominant (AA) genotypes account for 70% of the population. Similarly, since homozygous recessive (aa) alleles make up 9% of the population, we can infer that the frequency of the recessive allele, a, is 0.09, or 9%.
The formula 2pq = frequency of heterozygotes, where p is the frequency of the A allele and q is the frequency of the an allele, can be used to determine the frequency of the heterozygous genotype (Aa).
We know that the frequency of heterozygotes is 0.21, or 21%.
Plugging in the known values:
2 * 0.7 * q = 0.21
Solving for q:
q = 0.15
So, the frequency of the A allele is 0.7, and the frequency of the a allele is 0.09.

1. How does calcium ion concentration in blood affect muscle contraction? Does it lead to tetany in certain cases? How will you correlate fluctuation in blood calcium with tetany?
Answers
Calcium ion concentration in the blood affects muscle contraction because actin and myosin filaments return to their initial places as calcium ions leave the muscle cells, causing the muscle to relax.
The muscle relaxes as calcium ions leave the muscle cells, causing the actin and myosin filaments to return to their initial positions. In other words, a lower calcium level in muscles is indicated by a larger level of calcium ions in the blood. Muscle contraction will suffer as a result of this.
Muscle contraction results from the thin and thick filaments sliding apart from one another when Ca2+ is present in the cytosol. Similar to this, as the Ca2+ level drops, the binding sites are covered, causing contraction to cease.
Low calcium levels in bodily fluids due to impaired parathyroid gland function occur in cases of tetany. Periodic, excruciating muscle spasms (wild contractions) and trembling are symptoms of tetany.

The number of chromosomes found in human somatic cells is 46, what is the human
haploid number?
Answers
Answer:
Explanation:
La cellule humaine comprend 46 chromosomes, porteurs du code génétique de l'espèce humaine. Le nombre de chromosomes est de 46 chez l'homme : 22 paires d'autosomes et 2 chromosomes sexuels ou gonosomes, XX chez la femme et XY chez l'homme.
Chromosomes present in the human body are in a pair of 23. These 23 pairs of chromosomes are also divided into two sub-division called autosome and sex chromosome. The autosome is 22 in pair and the sex chromosome are 1 in pair.
Autosomes help in inheriting the characteristics from parent to offspring, whereas sex chromosome help in determining the sex of the offspring. Therefore, the human haploid number is n = 23, haploid number refers to the number of chromosomes present in a single set that is denoted by n. Each of these chromosome pairs exists with diploid cells.
Hence, humans are diploid containing 46 chromosomes that divide to half forming 23 pair of chromosomes.

Give an example of a situation where gene expression without regulation could potentially harm an organism.
Answers
An example of a situation where gene expression without regulation could potentially harm an organism is in the development of cancer.
Cancer is often caused by mutations in genes that control cell growth and division. These mutations can cause these genes to be expressed in an unregulated manner, leading to uncontrolled cell growth and the formation of tumors.
Without regulation of gene expression, the cell can continue to divide and grow out of control, eventually leading to the development of cancer. Gene regulation mechanisms, such as DNA methylation, histone modification, and microRNA, are critical in preventing the uncontrolled expression of genes that can lead to cancer.
Thus, the regulation of gene expression is essential for maintaining normal cellular function and preventing the development of diseases like cancer.

Which sequence correctly represents the order of events during egg formation?
Answers
Answer:
The egg is made by the hen. It creates an embryo (the future chick, the little white spot that you see on the egg yolk) which will be fed by the yolk of the egg.
The yolk is a food reserve (called the yolk) for the chick in formation: by eating the yolk, the embryo becomes a chick.
The white consists of gelatinous proteins, which the future chick will eat during incubation, warm for 21 days under the hen.
The shell protects the embryo, the yolk and the white. It is made of two membranes that are made from calcium that the hen stores in her bones and intestines. In the chicken's belly, muscles spin the egg during training and give it its perfect shape.
The shell is made in such a way that it is difficult to the pan from the outside, but very easy to break it from the inside. So the hen does not crush her eggs when she is brooding, but the chick can come out easily!
It works pretty much the same for all birds, reptiles, fish ... that lay eggs. On them, moreover, oviparous animals.

which of the six basic nutrient might a person need to restric after an operation to remove the gallbladder? why?
Answers
You need to restrict lipids as the bile works on fats which is stored in the gall bladder until secretion.
What is Gall bladder?One of those organs that you usually don't give much thought to till something goes wrong is the gallbladder.
Bile, which aids in the body's breakdown and digestion of the fats you consume, is its primary purpose. It doesn't make bile; your liver does, and it enters your small intestine during meals via the common bile duct.
The majority of bile produced by the small intestine is transported to the gallbladder, where it is stored until it is required again. In the small intestine, where partially digested food is also present, your gallbladder releases bile when you ingest fatty meals.
