Biology

A scientific theory developed by many different experiments are performed and repeated

Answer: Option D

<u>Explanation:</u>

Hypothesis is an experimental analysis where it is not a perfectly proven fact but a guess due to continuous observation over the years. Hypothesis is the foundation for further discoveries and theories.

Theories are based on the group of hypothesis. Theories are not fixed based to prove on the hypothesis, if any alterations are found they repeat it with more innovative ideas. Over the years continuous and repeated experiments are conducted on the same. Theory is an explanation that is given for the hypothesis by conducting various experiments and continuous observation time and again to prove it.

A law is a proved theory. It is more of mathematical derivations and calculations with precision. A 100% proved theory after observation only can be considered as a law.

Researchers have crossed two true-breeding lines of peas that differ in the color of their leaf tissue: dark green vs pale green
amid [387]

Answer:

150 individuals

Explanation:

If the dark phenotype is determined by a dominant allele at a single locus, the ratio of dark green phenotype to pale green phenotype at F2 should be 3:1 according to the Mendelian standard.

200 to 3:1 = 150:50

<u>Hence, if 200 F2 individuals were characterized, one would expect the number of dark green individuals to be 150 while the pale green would be expected to be 50.</u>
