Do you think the shape of orchids is pure Mendelian inheritance, or is it more complex?
Mandarinka [93]

The genetic base of the shape of orchid is very complex.

Mendelian traits are described as simple traits determined by one gene. The different alleles of the gene contribute to the difference in the trait. This is true for some traits in plants, animals including humans and other organisms, but not for the shape of orchids.

The shape of orchid flowers is determined by the ABCDE group of genes that are responsible for the body plan in plants. These genes are the equivalent of HOX genes of animals.

The protein products of different genes of the ABCDE group interact with each other in complex ways creating different shapes of orchids.

In a certain breed of plants, dark green is determined by the dominant gene 'G' and light green is determined by the recessive g
stealth61 [152]

Answer:

The answer is 300.

Explanation:

When we cross GG and gg, 100% of the offspring will be heterozygous. If the heterozygotes show 75% penetrance meaning that there is a 75% probability that the plant that has the G gene will actually show it in it's phenotype.

So that means that 75% of the offspring should have dark green color, which means that 300 plants will have the expected phenotype and 100 will not.

I hope this answer helps.

Explain the effects of osmosis on cells and tissues:
viva [34]

Answer:

In explanation.

Explanation:

Effect of osmosis on cells:

-Osmosis is the movement of water across a cell membrane. Cells use osmosis to maintain concentration equilibrium (the concentrations of solute inside and outside the cell are equal). Changing the amount of water allows the cells to achieve equilibrium.

Effects of osmosis on tissues:

-Red blood cells placed in a solution with a higher water concentration compared to their contents (eg pure water) will gain water by osmosis, swell up, and burst. Water will diffuse from a higher water concentration outside the cell to a lower water concentration inside the cell.

Hope this helps.
