a) to investigate the effect of the force of gravity on the growth of a seedling
(shoot and root);
b) Force of gravity cause accumulation of auxins on the lower side of the seedling
- Higher concentration of auxin will promote growth in the shoot but inhibit growth in the
Roots;
- There will be more/ faster growth on the upper side of the root than on the lower side hence
the downward bending;
-There will be more/ faster growth on the lower side of the shoot than on the upper part hence
the upward curvature;

In a certain bird species, red flight feathers is controlled by gene R while white flight feathers is
controlled by gene r. The heterozygous condition Rr results into pink flight feathers. The two
genes are also sex linked and transmitted on x-chromosome.
a) By use of fusion lines, find the genotypes of across between a male with pink flight
feathers and a female with white flight feathers
b) Which type of dominance is illustrated here?
