One of the major negative factors from urbanization is A. impervious surface, creating more runoff and less fresh water infiltration.
Runoff refers to the draining of water, which happens more and more as societies progress and advance, and as new towns and cities are created as a result of urbanization. Also, there will be less and less fresh water, which is why urbanization needs to be controlled.
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.
Cross: a green-seeded plant with a yellow-seeded plant
Parental) YY x yy
Phenotype) Yellow seeds Green seeds
Gametes) Y Y y y
Punnet square) Y Y
y Yy Yy
y Yy Yy
F1) Phenotype: 100% of the progeny will be yellow-seeded
Genotype: 100% or 4/4 of the progeny will be heterozygous for the trait
