Unicellular organisms such as <em>Amoeba</em>, <em>Paramecium</em> depend on diffusion to move substances into and out of the cell. The surface area of unicellular organisms is large compared to its volume. Therefore, nutrients and other substances can easily cross the membrane and around their body.
As a cell's volume grows, its surface area/volume ratio <u>decreases</u>, making it <u>more difficult</u><u> </u>to acquire enough nutrients via diffusion.
Males have a X and Y chromosome while females have 2X chromosomes. So a Y linked gene will not be able to be passed on to females, only to males and all males will have the dominant gene and expressing the phenotype. Whereas for X linked gene, females can be recessive or dominant for that gene Xa, XA thus may or may not have the phenotype whereas once males inherit the dominant XA allele, they will express the phenotype as males only have one X chromosome. Hope I helped!
