The correct answer is A. Inhale odor molecules into nasal cavity.
You will have to expand more on this but I think it is helpful to make things more efficient to what we need them for and it could make a positive impact in that way but also negative impacts could be deformities or diseases by changing some things genetic makeup
Here we can see that 7 phenotypes appeared in F2 generation, so the number of genes involved is 3 and alleles is 6. Contribution per allele = 4 cm Base contribution = 6 cm
Genotype of Harvey = aa bb cc Genotype of Erma = AA BB CC
Number of dominant alleles if length is
18 cm = 18-6 / 4 = 12 / 4 = 3.
F1 generation genotype = Aa Bb Cc This clarifies why the length is 18 cm, as there are three dominant alleles.
seven 1. It is likely that there are gene pairs in this cross. There are
categories of phenotypes. The genotypes of the parents would be combinations of alleles that would produce a 6 cm ( aabbcc ) tail and a 30 cm) tail, whereas the 18 cm offspring would have a genotype of AaBbcc.

Propuso que la gran variedad de organismos, que en ese tiempo se aceptaba que eran formas creadas estáticas por Dios, había evolucionado de formas simples; <span>los protagonistas de esa evolución han sido los propios organismos por su capacidad de adaptación al ambiente: los cambios en el ambiente generan nuevas necesidades en los organismos y las nuevas necesidades conllevan una modificación de los mismos que pueden ser heredables.
