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

riety (ss). The heterozygous F1 tall plants (Ss) were crossed to produce two sets of F2 data, as follows.Set I= 63 tall, 16 short Set II= 630 tall, 160 shortPart A What is the chi square value for Set I?

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.

tiny-mole [99]

Answer:

<h2>Dense connective tissue.</h2>

Explanation:

This is a type of connective tissue that has fibers, which are composed of collagen. You can refer to the image attached to see the parallel bundles of these collagenic fibers.

So, basically this formations help to forms strong tissue like tendons or ligaments.

Lera25 [3.4K]

Answer:

False.

It is not true that a rheumatologist specializes in diagnosing and treating diseases and disorders involving the bones, joints, and muscles.

Explanation:

  • A rheumatologist is a doctor who examines the internal medicine of patients in case of treating inflammatory conditions.
  • The rheumatologist treats and diagnoses the patients with problems related to different aspect that affects the joints, tendons, ligaments, bones, and muscles.
  • It is a basic fact that rheumatologist do not perform any surgery instead they treat musculoskeletal conditions.
  • So they do not treat any disorders of bones or joints but they diagnose the inflammatory conditions affecting the bones and joints.
