Answer:
All progeny with heterozygous dominant genotype
Explanation:
Mendel crossed two pure breeding pea plants with respect to one genetic trait. He found that the F1 progeny obtained by crossing two pure breeding parent plants is always heterozygous dominant. The phenotype of the F1 progeny was always the phenotype of the dominant pure breeding parent plant.
For instance, purple flower color is a dominant trait over the white flower color in pea plants. When he crossed a pure breeding purple-flowered pea plant (PP) with a pure breeding white-flowered pea plant (pp), the F1 progeny was expressed the phenotype of the dominant parent and had purple flowers. The genotype of the F1 plants was Ww (heterozygous dominant).
Natural Selection, unless you were born in a lab which would be unnatural/artificial, and not too likely with today's technology. (Maybe one day.)
1) Arithmetic density- the number of people per square unit of land
2) Physiologic density- Is the number of people per square unit of farmland.
3) Agricultural density- is the number farmers per unit of farmland.
Viruses are not considered "alive" because they lack many of the properties that scientists associate with living organisms. Primarily, they lack the ability to reproduce without the aid of a host cell, and don't use the typical cell- division approach to replication.
Answer:
d. no one knows for sure
Explanation:
The universe is infinitely big. It goes on forever and ever, so no one knows what's in it. We might find something really big, but we'll never know if there's something even bigger out there.
