The difference between topsoil and garden soil is an even finer distinction than the difference between soil and dirt, and it has to do with the amount of organic matter, and to a lesser extent, the types of trace minerals and the ratio of clay, sand and silt. Garden soil is a category of topsoil
The offspring will inherit one allele from each parent.
<h3><u>Explanation</u>:</h3>
The genetic crossing experiments lead to the formation of different hybrids which has several characters unlike their parents. Here the parents are homozygous.
One of the parent is homozygous yellow with respect to seed colour. So genetic combination of the parent will be YY.
The other parent is homozygous green with respect to seed color. So genetic combination of the parent will be yy.
Now as they are crossed the offsprings will have genetic combination of Yy.
This is seen that the offsprings carry one allele from both the parents.
Answer:
The correct answer is - increase in frequency.
Explanation:
According to the theory of Darwin, organisms most likely survive and reproduce in an ecosystem that is able to change or adapt to the changes in the ecosystem.
According to the modern evolutionary theory that the genes that are responsible for new changes or traits that help a species to reproduce and survive in a particular environment increase in frequency and the genes do not helps decrease in frequency.
