    Selection of homozygous plant is

    • Mass selection

    • Pure - line selection

    • Mixed selection

    • None of the above

    Correct Answer
    A. Pure - line selection
    Explanation
    Pure-line selection is the correct answer because it refers to the process of selecting and breeding plants that are homozygous for a particular trait. Homozygous plants have two identical alleles for a specific gene, which ensures that the desired trait will be consistently expressed in future generations. Pure-line selection involves isolating individual plants with the desired trait and allowing them to self-pollinate for several generations to establish a stable, true-breeding line. This method is commonly used in plant breeding to develop new cultivars with uniform traits.

    Mule is a product of

    • Breeding

    • Mutation

    • Hybridization

    • Interspecific-hybridization

    Correct Answer
    A. Interspecific-hybridization
    Explanation
    Mule is a product of interspecific-hybridization, which means it is the result of breeding between two different species. In the case of mules, the two species involved are a male donkey and a female horse. This crossbreeding leads to the creation of a mule, which inherits certain traits from both parent species. Mules are known for their strength, endurance, and ability to adapt to harsh environments, making them valuable working animals in agriculture and transportation.

    Manipulation of plants in vitro to produce new varieties can be done by

    • Grafting

    • Tissue culture

    • Chemical treatment

    • None of these

    Correct Answer
    A. Tissue culture
    Explanation
    Tissue culture is a technique used to manipulate plants in vitro to produce new varieties. It involves the growth of plant cells, tissues, or organs in a sterile, nutrient-rich medium. This method allows for the production of genetically identical plants, which can be used for various purposes such as improving crop yields, developing disease-resistant varieties, or creating new ornamental plants. Grafting and chemical treatment, on the other hand, are different methods used for specific purposes, but they do not involve the manipulation of plants in vitro to produce new varieties.

    • None of these

    Correct Answer
    A. Pure-line
    Explanation
    The progeny of a single homozygous self-pollinated plant is referred to as a pure-line. This means that the offspring inherit the same genetic traits as the parent plant, resulting in a genetically uniform population. Pure-lines are often used in breeding programs to maintain specific traits and characteristics in plants.

    A lake with an inflow of domestic sewage rich in organic waste may result in;

    • Drying of the lake very soon due to algal bloom

    • An increased production offish due to lot of nutrients

    • Death of fish due to lack of oxygen

    • Increased population of aquatic web organisms

    Correct Answer
    A. Death of fish due to lack of oxygen
    Explanation
    When a lake receives domestic sewage rich in organic waste, it leads to an excessive growth of algae, known as algal bloom. As the algae multiply rapidly, they consume a large amount of oxygen in the water during respiration. This depletes the oxygen levels in the lake, resulting in a condition called hypoxia. Fish and other aquatic organisms rely on dissolved oxygen in the water to survive. With the lack of oxygen, fish are unable to breathe properly and may eventually die. Therefore, the correct answer is death of fish due to lack of oxygen.

    • Natural selection

    Correct Answer
    A. Hyhridization
    Explanation
    Hybridization is a technique that can be used to raise the desired improved variety of economically useful crops. It involves the crossing of two genetically different plants to create offspring with desirable traits. This process allows for the combination of beneficial characteristics from both parent plants, resulting in a new hybrid variety that exhibits improved qualities such as higher yield, disease resistance, or better nutritional value. Hybridization is widely used in agriculture to develop new crop varieties that can meet the demands of an ever-growing population and improve agricultural productivity.

    In poultry industry, production of hatching eggs is more expensive than the production of market eggs mainly because;

    • Cost of males and their depreciation value is high

    • Mortality among females is usually lower when they are mated with males

    • Number of eggs produced by hatchery flocks are to be sold only as market eggs

    • Some of the eggs produced by hatchery flocks are not acceptable for incubation

    Correct Answer
    A. Some of the eggs produced by hatchery flocks are not acceptable for incubation
    Explanation
    Some of the eggs produced by hatchery flocks are not acceptable for incubation. This means that not all the eggs laid by the hens can be used for hatching. Some of the eggs may be damaged, infertile, or have other abnormalities that make them unsuitable for incubation. As a result, the hatchery has to sell these eggs as market eggs instead of using them for hatching, which reduces their potential revenue from hatching eggs. This additional cost and loss of potential revenue contribute to the higher expense of producing hatching eggs compared to market eggs in the poultry industry.
