    Mendel crossed pure lines of pea plants. Dominant traits, like purple flower colour, appeared in the first-generation hybrids (F1), whereas recessive traits, like white flower colour, were masked. However, recessive traits reappeared in second-generation (F2) pea plants in a ratio of 3:1 (dominant to recessive).

    Thalassemia is an inherited blood disorder in which the body makes an abnormal form of hemoglobin. Hemoglobin is the protein molecule in red blood cells that carries oxygen. The disorder results in excessive destruction of red blood cells, which leads to anemia.

    Color blindness is an abnormal condition characterized by the inability to clearly distinguish different colors of the spectrum. The difficulties can range from mild to severe. It is a misleading term because people with color blindness are not blind.

    In honey bees, the male is haploid while the female is diploid. Haplodiploidy occurs in some insects like bees, ants and wasps. Male insects are haploid because they develop partheno-genetically from unfertilized eggs. The phenomenon is called arehenotoky. Meiosis does not occur during the formation of sperms. Females grow from fertilized eggs and are hence diploid. Queen bee picks up all the sperms from the drone during nuptial flight and stores the same in her seminal vesicle. Formation of worker bees(diploid females) and drones(haploid males) depends upon the brood cells visited by the queen. While visiting the smaller brood cells, the queen emits sperms from its seminal receptacle after laying the eggs. Males are normally fertile haploids due to development from unfertilized eggs. Occasionally diploid infertile males are also produced from heterozygous females through fertilization.

    Turner syndrome is a rare genetic disorder that’s found only in girls. It can cause problems ranging from short height to heart defects. Sometimes, the symptoms are so mild that it doesn’t get diagnosed until a female is a teen or young adult.

    Klinefelter's syndrome isn't inherited, but rather occurs only as a result of a random genetic error after conception.

    Males born with Klinefelter's syndrome may have low testosterone and reduced muscle mass, facial hair and body hair. Most males with this condition produce little or no sperm.

    Treatment may include testosterone replacement and fertility treatment.

    Down's syndrome is a genetic disorder caused when abnormal cell division results in extra genetic material from chromosome 21.

    Down's syndrome causes a distinct facial appearance, intellectual disability and developmental delays. It may be associated with thyroid or heart disease.

    Early intervention programmes with a team of therapists and special educators who can treat each child's specific situation are helpful in managing Down's syndrome.

    Euploidy is a chromosomal variation that involves the entire set of chromosomes in a cell or an organism. Other types of euploidy are autopolyploidy and allopolyploidy. In autopolyploidy, there is an additional set of chromosomes, which may be from a parent or identical parental species (i.e. a single taxon).

    Polyploidy is a condition in which the cells of an organism have more than two paired sets of chromosomes. Most species whose cells have nuclei are diploid, meaning they have two sets of chromosomes—one set inherited from each parent.

    Ploidy is the number of complete sets of chromosomes in a cell, and hence the number of possible alleles for autosomal and pseudoautosomal genes. Sets of chromosomes refer to the number of maternal and paternal chromosome copies, respectively, in each homologous chromosome pair, which chromosomes naturally exist as.

    Point mutation is the mutation that affects a single nucleotide or nucleic acid. It commonly occurs when one base is substituted for the other. It may also result due to insertion and deletion of a single base pair. 

    Examples of point mutation are:

    • Cystic fibrosis: It occurs due to the deletion of three nucleotides in the CFTR gene. In this, an amino acid phenylalanine is lost which causes misfolding of protein.
    • Sickle cell anemia: It is caused by single point mutation in the beta haemoglobin gene. This results in the conversion of GAG codon into GUG that encodes amino acid valine.

    In biology, a mutation is an alteration in the nucleotide sequence of the genome of an organism, virus, or extrachromosomal DNA. Viral genomes contain either DNA or RNA. Mutation is the ultimate source of all genetic variation, providing the raw material on which evolutionary forces such as natural selection can act.

    Pedigree analysis is the study of a particular trait that is inherited from one generation to another. During these days in many cases, including various species of plant and animal, scientists are using the pedigree analysis to analyze the inheritance of phenotypes, or traits, using mating experiments called crosses.
    Pedigree analysis is like a chart that represents a family tree, which displays the members of the family who are affected by a genetic trait or having a genetic disorder or maybe carrier of the disease.
    In the family tree, the rows represent the generations of a family, squares represent the males and circles represent the females.
    The pedigree analysis helps to know the trait of inheritance for a particular trait, and also know whether the trait is getting inherited or not.

    Polygenic inheritance occurs when one characteristic is controlled by two or more genes. Often the genes are large in quantity, but small in effect. Examples of human polygenic inheritance are height, skin color, eye color and weight. Human skin color is a good example of polygenic (multiple gene) inheritance.

    Pleiotropy is defined as the expression of multiple traits by a single gene. Pleiotropy is derived from a Greek word meaning more ways. A simple example of a Pleiotropy is phenylketonuria is a disease. It is a genetic disorder caused by the low metabolism of the amino acid phenylalanine in the body cells.

    (i) Super Profit Method:

    Step 1: Calculation of Capital Employed:

    Capital Employed= 300000

    Step 2: Calculation of Normal Profit:

    Normal Profit= 300000 * [10/100]

    = 30000

    Step 3: Calculation of Average Profit:

    Average Profit= 50000

    Step 4: Calculation of Super Profit:

    Super Profit= 50000-30000

    = 20000

    Step 5: Calculation of Goodwill:

    Goodwill= Super Profit * Number of years' of purchase

    = 20000 * 3

    = 60000

    (ii) Capitalisation of Super Profit Method:

    Step 1: Calculation of Capital Employed:

    Capital Employed= 300000

    Step 2: Calculation of Normal Profit:

    Normal Profit= 300000 * [10/100]

    = 30000

    Step 3: Calculation of Average Profit:

    Average Profit= 50000

    Step 4: Calculation of Super Profit:

    Super Profit= 50000-30000

    = 20000

    Step 5: Calculation of Goodwill:

    Goodwill= Super profit* [100/Normal Rate of return]

    = 20000 * [100/10]

    = 200000

    People who move from one place to another in search of work or shelter are called migrants. Most of the times migrants people are not skilled or educated therefore they usually employed as daily wagers (workers who are paid at the end of each day, for their services). Daily wagers do not get enough money for the survival of their families and suffering from many problems such as they do not have enough food to eat, sanitation, hygiene, a proper place to live etc.
