Question

Genotype is referred to as the_________________

  1. Appearance of an organism.

  2. Genetic makeup of an organism.

  3. Behavior of an organism.

  4. Relative health of an organism.

hintHint:

Forms the basis for heredity.

The correct answer is:

Genetic makeup of an organism.


    • Genotypes include the genetic of an individual
    • The genes are the hereditary units
    • The gene are sequence of nucleic acids that code for a particular protein (trait)
    • Phenotypes are due to the expression of dominant genotype
    • No two individual appears similar due to the genotype
    • Any alteration in the genetic sequence is called mutation

    • Genotype of an individual is a combination of genes received from both parents
    • The offspring will exert the characteristics of the dominant alone, though the genotype contains both dominant and recessive alleles

    The idea that different alleles pairs are passed to offspring independently of each other is Mendel's law of:

    • The law of segregation is the basis for independent assortment

    • The assortment of the chromosomes into gametes occur randomly
    • Following segregation, recombination also occurs during meiosis
    • Combination of paternal and maternal genes can occur and a hybrid is formed

    • Law of segregation is the second law of inheritance
    • Law of inheritance is based on the following:
    1. Gene can exist in various versions called alleles
    2. During meiosis, separation of allelic pair occurs providing single allele to each gamete
    3. Organisms inherit two alleles for each phenotype
    4. In an allele pair, one is dominant while other is recessive
