Cross a heterozygous plant with a plant that has wrinkled seeds.

Round seeds are dominant to wrinkled seeds.

Explanation:

What would be the parent genotypes if you crossed a heterozygous with a wrinkled seed plant? Round seeds are dominant to wrinkled seeds. What percentage of the offspring would be round if you crossed a wrinkled seed plant with a heterozygous plant? Round seeds are dominant to wrinkled seeds.

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.
