To assess Mendel’s law of segregation using tomatoes, a true-breeding tall variety (SS) is crossed with a true-breeding short va
lapo4ka [179]

Answer:

0.949367 ≈ 0.95.

Explanation:

The chi square analysis can be done by the formula as follows:

Chi square = (O-E)²/E

Here, O is observed value and E is expected value.

The tall trait follows the Mendel's law, this means the cross between F1 results in the formation of progeny with ratio 3( tall) : 1 (short).

The observed values for set I is  63 tall, 16 short.

The expected value for tall plant =  \frac{3}{4}\times79 = 59.25 .

The expected value for short plant = \frac{1}{4}\times79 = 19.75.

Put these value in the formula for chi square analysis:

For tall plants = ( 63 - 59.25)²/ 59.25= 0.237.

For short plants = (16 - 19.75)²/ 19.75 = 0.712

Total value for set I = 0.237 + 0.712 = 0.95.

Thus, the answer is 0.95.

Explain how xylem cells are adapted for their function.<br>​
s2008m [1.1K]

Answer:

Xylem cells have no cytoplasm or end walls, meaning they form a tube through which water can pass freely to allow water transport. Lignin strengthens the cell walls, helping to support the plant.
