What is the probability that a cross between a true-breeding pea plant with spherical seeds and a true-breeding pea plant with w
notsponge [240]

Answer:

1 or 100%

Explanation:

Let the allele for seed shape be represented by S.

True breeding spherical shape seeded pea plant will have SS as genotype

True breeding pea plant with wrinkled seeds will have ss as genotype

Crossing the two:     SS  x   ss

Progeny: Ss, Ss, Ss, Ss

Based on the assumption that spherical shape allele is dominant over wrinkle shape allele, all the F1 offspring will have spherical seeds.

<em>Hence, the probability is 1 or 100%</em>

Grace [21]

Answer:Organ

Explanation:An organ may be defined as a group of tissues which perform similar functions. Organs can be found in both plants and animals,functionally related organs often cooperate to form systems. These organs are interdependent on each other to make up organ systems. Organ systems can be found in the different parts of the body. For instance,the esophagus,stomach and liver make up the digestive system and in the excretory system the skin and kidney are examples of the organs that can be found here. The main tissues of an organ tend to have the same embryological origin. This simply means that they arise from the same germ layer and by germ layer we mean the primary layer of cells that form during embryonic development. In plants however,the main organs are the roots,stem and leaves whose primary functions are to give nourishment to the plant. Reproductive organs of plants include the seed,flowers and spores which maintain the basic life processes of the plant.
