Question
Outcrossing and Crossbreeding.
✓

Answer

OutcrossingCrossbreeding
1. Breeding of animals of the same breed but having no common ancestors for 4 to 6 generations is known as outcrossing.1. Breeding of superior male of one breed with superior female of another breed is known as crossbreeding.
2. Progeny is known as outeross. 2. Progeny is known as hybrid.
3. New breeds are not developed by outcrossing.3. New breeds or hybrids are formed by crossbreeding.
4. An outcross helps to overcome inbreeding depression.4. Hybrids are subjected to inbreeding and new stable breeds are developed by crossbreeding.

Read the following and answer any four questions from (i) to (v) given below:
Alcohols are important industrial solvents. Ethanol, methanol, propanol and butanol are produced commercially by fermentation activity of some fungi, majorly yeasts. During fermentation, yeast cells convert cereal derived sugars into ethanol and $CO_2$ At the same time hundreds of secondary metabolites that influence the aroma and taste of alcohol are produced. Sugar concentration affects the rate of fermentation reactions. Yeast cannot grow in very strong sugar solution. In case of complex carbohydrate containing nutrient media, 1% malt or Rhizopus is used along with yeasts. Hydrolysis of starch is carried out at high temperature for 30 ruins. 'Tile crushed food mixed with hot water for obtaining malt in called mash. 'Tile nutrient medium prior to fermentation in called wort. Wort is cooled down to appropriate temperature and inoculated with strain of yeast.
  1. Tile rate of alcohol production is measured on the basis of:
  1. Amount of sugar present in the medium.
  2. Amount of $CO_2$ produced per unit time.
  3. Amount of yeast added in the medium.
  4. All of these.
  1. A number of chemicals are produced at the time of alcoholic fermentation with the change of nutrient media, pH and aeration. Select such by-product from the following.
  1. Phenylethanol.
  2. Amyl alcohol.
  3. Glycerol.
  4. All of these.
  1. During alcoholic fermentation of cereals and potato, the crushed food mixed with hot water for obtaining malt is called:
  1. Juice.
  2. Mash.
  3. Wort.
  4. None of these.
  1. Distilled alcohol with 95% ethanol content is called:
  1. Absolute alcohol.
  2. Rectified spirit.
  3. Gin.
  4. Brandy.
  1. Assertion: Rhizopus or 1% malt is used in the nutrient medium when it contains complex carbohydrates.
Reason: Yeast does not possess sufficient diastase or amylase.
  1. Both assertion and reason are true and reason is the correct explanation of assertion.
  2. Both assertion and reason are true but reason is not the correct explanation of assertion.
  3. Assertion is true but reason is false.
  4. Both assertion and reason are false.
