In a cross between pure-breeding tall plants with pure-breeding short plants, all of the f1 are tall. when these plants are allowed to fertilize themselves, the f2 plants occur in a ratio of 3 tall: 1 short.
which of the following is not a valid conclusion from these results? group of answer choices
a. the allele that produces the tall condition is dominant to the allele that produces the short condition.
b. the difference between tall and short stature in these lines is controlled by a single gene pair.
c. during production of gametes in f1 plants, the tall and short alleles segregate from each other equally into the gametes.
d. the tall and short traits assort independently of each other in this cross.
e. fertilization occurs randomly between gametes carrying the tall and short alleles.

d. The tall and short traits assort independently of each other in this cross.

Explanation:

In the given example, the alleles for tallness and shortness of the plant belong to the same gene. The dominant allele “T” makes the plants tall while the recessive allele “t” is responsible for short plants. During gamete formation, independent assortment segregates the alleles of two different genes randomly. This process produces some new allele combinations in the progeny. However, the process of independent assortment is not about the segregation of alleles of a single gene from each other.

clinically, some people often have repeated allergies, eczema and respiratory infections or other parts of the infection, in this case, in addition to some routine tests such as tests for white blood cells, immunoglobulin series, lymphocyte subsets, etc., the five immune immunoglobulin tests are also necessary.
