Re: I really need help with the Punnett square & genotypic

if there are 25% be Red, 50% Pink and 25% White, it means the red is incomplete dominant. when heterozygous, it wont be appeared as dominant phenotype, it will appear as pink colour.

In ur question,[(heterozygous) for red flower] this mean it is not incomplete dominant.

Mutation can be caused by many factors such as chemical (DDT, CCL4), radiation, ionizing etc. It mutate the DNA in cell. If only a single is mutated, it can be replicated as usual in mitosis. Thus, the neighbor cells which are previously normal will be affected too. Current way to stop the cancer pr...

Oxidation of one molecule of acetyl coA is the one Krebs cycle.

In one Krebs cycle, produce 3 NADH, 1FADH2, 1 GTP
1 NADH = 3 ATP x 3
1FADH2 = 2 ATP x 1
1GTP = 1ATP
______________
Total: 12 ATP

U have three acetyl CoA = 3 x 12 ATP = 36 ATP

Re: Mitosis and meiosis!

The difference is not on the S phase. The differences are the meiosis is the reduction of chromosomes number compared parent cell. In Meiosis Prophase I is different from Prophase in mitosis where there is crossing over occur. In Metaphase I, the homologous chromosomes are aligned at the equatorial ...
