    When crossing an organism that is homozygous recessive for a single trait with a heterozygote, what is the chance of producing an offspring with the homozygous recessive phenotype?

    a) 0%

    b) 25%

    c) 50%

    d) 75%

    e) 100%

    Homozygous Recessive Traits:

    If a trait is homozygous, it means that it has two of the same alleles. This is easy to remember because "homo" means the same, and "hetero" means different. A recessive trait means that the trait will not be expressed unless both alleles are the same. For example, if a trait only has one recessive allele and one dominant allele, it is called a heterozygote, and the dominant trait would be expressed (if there is complete dominance in the allelic trait). If the trait had two recessive alleles (which makes it homozygous), then the recessive trait would be expressed.

    The answer is 50%. Assume that the homozygous recessive trait is denoted by aa and the heterozygote is Aa. If you cross aa with Aa in a Punnett...

    An organism with a homozygous recessive genotype is made to undergo a test cross which results in 50% of the offspring exhibiting the recessive trait. The test cross parent is:
    I. Homozygous recessive
    II. Homozygous dominant
    III. Heterozygous

    I only

    II only

    III only

    I or III

    II or III

    A test cross is performed to determine the genotype of a dominant parent if it is a heterozygous or homozygous dominant. For the purpose, a dominant parent is crossed with the homozygous recessive parent. 
    Since the offspring from test cross has 50% recessive phenotypes, the test cross parent is heterozygous and fusion of gamete having the recessive allele with that of recessive parent gives 50% recessive progeny. 
    If the test parent was homozygous dominant, all progeny would exhibit only dominant phenotype. 
     Therefore, the correct answer is option C.

    When crossing an organism that is homozygous recessive for a single trait with a heterozygote, what is the chance of producing an offspring with the homozygous recessive phenotype?

    Answer (1 of 1): Use a Punnett Square, heterozygous genotype we can use Tt and homozygous recessive we can  use  tt (T as a dominant trait and t as a recessive) thus follows:  T  tt Tt  ttt Tt  tt50% Tt and 50% tt, thus your answer is 50% chance of having an offspring with the homozygous recessive phenotype in this case (tt).
