1. Petunias exhibit incomplete dominance for flower color. Predict the results of a cross between two petunia plans, one that is true breeding from red flowers and one that is true breeding for white flowers. Be sure to include the phenotypes and genotypes of parents and the F1 generation. 2 In question 1, you predicted the results of a cross between two petunia plants, one that is true breeding for ed flowers and one that is true breeding for white flowers. Predict the results of a cross between two of the F1 offspring described in question 1, including the phenotypic and genotypic ratios.

estuaries are the partially enclosed coastal bodies of brackish water formed at the mouth of sea where river meets an ocean. it is a transition zone between river and sea water so estuaries are influenced to both marine environment such as tides, waves and to riverine such as flow of fresh water and sediments. the mixing of sea and fresh water provide high level of nutrients, making estuaries a high product habitats.

many estuaries suffers degradation from a variety of human activities like erosion from deforestation, overgrazing, overfishing, drainage and eutrophication.

so from the above statement answers will be

1. false as estuaries are formed due to both brackish and freshwater.

2.true, due to high productivity estuaries are breeding ground for many marine species.

3. direct and indirect activities of man that contribute to pollution and deposition of sediments.
