the results of a test cross of a tall tomato plant was 100% tall. fill in the punnett square if all the recessive alleles (genes) came from pollen during the cross test.

t tt t tt tt

The punnet square should be filled as follows:

      T        T

t     Tt       Tt

t       Tt       Tt

The question says that the alleles from the male parent should be recessive hence tt are the alleles from the male parent.

The question also tells that all the offsprings produced were tall. Hence, for these results to occur, the female parent should be homozygous dominant for the trait. Hence, the alleles TT are from the female.

The offsprings produced will be heterozygous dominant.

they each offer a fresh glut of resources to the organisms that can arrive and exploit them. as individuals and new species continue to appear, they actively and passively alter the environment. competition for shared resources increases, local abiotic and biotic conditions shift, and the relative abundances of species change accordingly. the process is called ecological succession, and it is one of the earliest and most well-known concepts in ecology.
