Answer:
Genotype: 100% or 4/4 of the progeny will be heterozygous for the trait, Yy.
Explanation:
<u>Available data:</u>
- Two plants differ in the seed color they produce.
- One plant produces green seeds, the other produces yellow seeds.
- Yellow is the dominant phenotype, over green which is the recessive phenotype
- The parental plants are true-breeding
Let us say that the allele Y expresses yellow color and is dominant over the allele y which expresses the green color and in the recessive one.

F1) Phenotype: 100% of the progeny will be yellow-seeded
Genotype: 100% or 4/4 of the progeny will be heterozygous for the trait
Answer:
The correct answer is "low concentration of oxygen".
Explanation:
One of the key characteristic of aquatic dead zones is its low concentration of oxygen. Aquatic dead zones are classified into this category for being hypoxic, condition that do not support the growth of most marine life. Most aquatic dead zones are in these conditions because of a high content of nutrient pollution caused by human activities.
