Answer:
2. The gene responsible for eye color is on the X chromosome.
Explanation:
<em>For X-linked genes, a male can either be affected or unaffected because the Y chromosome is hypothesized not to carry any gene. Females on the other hand can be a carrier, affected or unaffected because the two sex chromosomes carry genes.</em>
If eye color allele in drosophilia is represented by R, the cross between F1 red-eyed heterozygous female and red-eyed males can be illustrated below:
Red-eyed heterozygous female =
Red-eyed male =
x
Progeny:
Out of the 2 male progeny from the cross, 1 () is white-eyed while the remaining one () is red-eyed
Hence, the result shows that the gene for eye color in Drosophilia is X-linked.
Option 2 is the correct answer.
It’s proximity to the Pacific Ocean.
Explanation: Vancouver has an oceanic climate and has, in winter, the second highest average temperature in the country, just behind Victoria. Its summer, however, is one of the mildest in the country.
The limitations of cell size are:
1) Surface area to volume ratio
2) Nucleo cytoplasmic ratio
3) Fragility of cell membrane
What are the cause of limitations on cell size?
The need for a surface area of sufficient area to allow the cells function→.
→If the surface area of cell increase volume increase to the cube of the linear increase.
→ Nuclie contains information needed for protein synthesis . Some cells reduce this limitation to increase the no. Of nucleus called multinucleated.
Examples are muscle cells.
