This is an illustration of X-linked recessive inheritance. This is a result of the mutation of genes on X-chromosomes. As females carry two X chromosomes, one from each parent, there is less chance for a female to carry mutant copies on both the X-chromosomes.
As males possess only one X-chromosomes, obtained from the female parent, one changed gene is adequate to result in a mutant phenotype. All the males exhibit a mutant phenotype as the male parent cannot transfer the X-linked traits to the progeny.
Answer:
The sporangiophore grow vertically which is in an upward direction because it is positively phototrophic. This means that it grows towards the ray of light from the sun which is found above. This is usually due to the provision of solar(light) energy from the sun which is used for the photosynthetic processes of the plants
The rhizoides grow downwards because they are positively geotrophic. This means they grow according to the force of gravity which acts downwards.
