<span>The toxin Bt (endotoxin
CrylA (b)) Bacillus thuringiensis that
is a normal inhabitant of the soil, showed himself as a natural insecticide
used by farmers engaged in organic farming. In contrast to the Bt-toxin
produced by bacteria, genetic engineers included it pesticide in every cell of
the seed, and therefore distributed throughout the adult plant, the products
from which then are consumed by man. </span>That's why scientists are concerned that after the use of a BT toxin
products people get antibiotic resistance and resistance to bt.
C. How can we make an artificial heart
In order to determine the results from a father who is homozygous recessive for the tongue rolling trait, T, and a mother who is heterozygous for the trait, a Punett square can be used to determine both the resulting genotype (allele combination) and phenotype (observable characteristics). The results are 50% Tt and 50% tt. Thus, the cross would result to 1:1 ratio of tongue rolling to non-tongue rolling offsprings.
