If a pea plant has a genotype sstt, what are the possible genetic combinations that could be present in a single grain of pollen produced by the plant? (2 points) ss, tt, st st, st, st ss, tt, st, st st, st

ST, St.

Explanation:

As per the question, each cell of the pea plant is diploid and contain genotype SSTt. Thus each microspore mother cell in the anther is also had genotype SSTt.  As a result of meiosis in the microspore mother cell, four haploid microspores or pollen grains are formed in the pea plant. As per Mendel’s law of segregation or purity of gametes, genotypically two types of pollen will form. Half of the pollen will have ST genotype and half of the pollen will have St genotype. Therefore, option D is correct.

answer; /// i do believe its (heredity); good luck

evidence and logical support is essential for a scientist to do in order to maintain credibility. this is because no one can believe without any logic and without any evidence.hence a scientist can maintain credibility by proving himself and by answering logically so experiments prove very beneficial. logical hypothesis give conclusion which is acceptable. therefore, there are two main factors to maintain credibility by a scientist is evidence and logical support.
