Answer:

The last one, " Peas have characteristics that have two forms. "

Explanation:

1. Peas grow very slowly. ( false they grow very fast...well you know...for a plant they grow fast )

2. Pea reproduction cannot be controlled. ( fun fact he actually separated some parts in the plant to control their reproduction...so this also false)

3. Peas normally produce very few offspring. ( also false they reproduce quickly )

4. Peas have characteristics that have two forms. ( yes they do )

Answer: Peas have characteristics that have two forms

Explanation: He chose peas because they had been used for similar studies, are easy to grow and can be sown each year. Pea flowers contain both male and female parts, called stamen and stigma, and usually self-pollinate. Self-pollination happens before the flowers open, so progeny are produced from a single plant.

IceJOKER [234]

Incomplete dominance is when a cross between two true breeds (homozygous) having different genotypes and phenotypes result in an heterozygous offspring expressing a third trait, usually a blend of those of the parents.

An example is crossing between red and white roses resulting in pink roses.

The condition to conclude incomplete dominance is that the heterozygous individual expresses a trait which is different from, and is a blend of, the traits of the parents.

Answer:

The correct answer will be-

1. DNA is found in the nucleus of a cell

2. Organisms store and transmit genetic information

3. Cells contain protein molecules.

Explanation:

The study of DNA started much before the discoveries of Rosalind Franklin and Maurice Wilkins.

Nucleus of cell was discovered by Robert Brown in 1831 but the material present inside the nucleus called "nuclein" (DNA) came from the studies of Johann Friedrich Miescher in 1869.

Proteins as a constituent of cell were discovered by the experimental analysis of Gerhardus Johannes Mulder in 1837.

DNA as a genetic material came from the experimental studies of Frederick Griffith in 1928, Oswald Avery, Maclyn McCarty, and Colin MacLeod in 1944, and Hershey and Chase in 1952.

Franklin and Maurice Wilkins are known for their work on the the structure of DNA as they were able to produce high-resolution X-ray photographs of DNA fibres called Photo 51 in 1952 using X-ray diffraction technique. By 1953 Franklin concluded concluded that DNA shows helical structure with phosphates on outer side.

Thus, 1. DNA is found in the nucleus of a cell

2. Organisms store and transmit genetic information

3. Cells contain protein molecules.

are the correct options.
