Question- what did mendel's cross-pollination of pea plants prove? a- each parent only passes on one-half of its heredity factors of each offspring. b- it takes four generations of offspring to identify the parents' factors c- there is no such thing as a true-breeding plant; they all have hidden factors d- inherited factors combine in offspring to create entirely new characteristics.!

Pea plants have both male and female reproductive organs. As a result, they can either self-pollinate themselves or cross-pollinate with another plant. In his experiments, Mendel was able to selectively cross-pollinate purebred plants with particular traits and observe the outcome over many generations.

The main role of dna in the  cell is the long-term storage of information. it is often compared to a blueprint, since it contains the instructions to construct other components of the  cell, such as  proteins  and rna molecules.the main function of rna is to carry information of amino acid sequence from the genes to where  proteins  are assembled on  ribosomes  in the  cytoplasm. mark brainliest, my work is good.
