Passage

Gregor Mendel is known for his work in genetics. He is credited with discovering how traits (characteristics) are passed from one generation to the next. After his observations of inherited traits, Mendel concluded that each organism carries two sets of information about a certain trait.
If the two sets differ about the same trait, one set dominates the other. That way, information can be passed on through the generations, even if the trait is not expressed.
It has since been determined that the presence of certain traits is attributed to genes, and the different forms that genes can take, known as alleles. Dominant alleles (D) produce dominant characteristics; recessive alleles (d ) produce recessive charactersitics. Dominant alleles are expressed whenever present (DD, Dd) but recessive alleles are expressed only when the dominant allele is absent (dd).
A study was done in which the independence of two traits was tested. In this study, a rabbit with long black hair was mated with a rabbit with short white hair. The dominant trait for hair length is short (H). The dominant trait for hair color is black (B). If the two initial rabbits (level 1 in the figure below) are homozygous for their traits, meaning that the two alleles for each trait are the same, breeding them will result in offspring that have both a dominant and recessive allele for each trait. Such a pairing of alleles is known as heterozygous. If, as in level 2 of the figure, two heterozygous rabbits are bred, the chart (level 3) contains all the possibilities for their offspring.
Q. Which of the following statements might be a reasonable generalization made after examining this study?
  • a)
     If heterozygous rabbits with opposite traits are bred, the recessive traits will be visible in the immediate generation and in the second generation.
  • b)
    If heterozygous rabbits with opposite traits are bred, the recessive traits might be visible in the immediate generation, but will not be visible in the second generation.
  • c)
    If heterozygous rabbits with opposite traits are bred, the recessive traits will not be visible in the immediate generation, but may be visible in the second generation.
  • d)
    If heterozygous rabbits with opposite traits are bred, the recessive traits will not at all be visible in future generations because they are overcome by the dominant traits.
Correct answer is option 'C'. Can you explain this answer?

The correct answer is:
c) If heterozygous rabbits with opposite traits are bred, the recessive traits will not be visible in the immediate generation, but may be visible in the second generation.
Explanation:
In the study, the dominant traits for hair length (short) and color (black) are expressed when present. Heterozygous rabbits have one dominant and one recessive allele for each trait. This means that in the immediate (first) generation, the dominant traits (short hair, black color) will be visible because the dominant allele will be expressed.
However, the recessive traits (long hair, white color) will not be visible in the immediate generation since they are masked by the dominant traits. Recessive traits can only be visible if both alleles for the trait are recessive (homozygous recessive, such as "hh" for hair length). Therefore, these recessive traits could appear in the second generation if the offspring inherit the recessive alleles from both parents.
Thus, answer c is the best generalization because it correctly states that the recessive traits may appear in the second generation, but not in the immediate (first) generation.
