There are quite a few ways that seeds can be dispersed. A few examples could be by wind (like dandelions), water (like water lilies or coconuts), or animals (through friut eaten by birds or other animals).
Even though the cladistic system organizes and clasifies organisms, the option that is not a characteristic is that it ranks organisms. This system <span> of classification is based on the phylogenetic relationships and evolutionary history of groups of organisms. It does not rank them</span>
Answer:
The cosmic microwave background (CMB) is thought to be leftover radiation from the Big Bang, or the time when the universe began. As the theory goes, when the universe was born it underwent a rapid inflation and expansion. ... The CMB represents the heat left over from the Big Bang.
Human height is one of the traits that belong to traits that cannot easily be placed in discrete phenotypic classes (there is not only tall and short people, there is continuous variation of height between them). Such traits are usually controlled by more than one gene (polygenic traits).
On the other hand, a Mendelian trait is controlled by a single locus.
Answer and Explanation:
- The phenotype of the heterozygous plant is
green pods
- The genotype of the heterozygous plant is Aa
- The genotype of the plant with yellow pods is aa
- The genotype of the gametes produced by the heterozygous plant is 50% A 50% a
- The genotype of the gametes produced by the plant with yellow pods is 100% a
- The expected frequency of F_1 plants with yellow pods is 50%
- The expected frequency of F_1 plants with the genotype AA is 0%
Cross) a heterozygous plant is crossed with a plant that has yellow pods
Parental) Aa x aa
Phenotype) Green pods Yellow pods
Gametes) A a a a
50% 50% 100%
Punnet Square) A a
a Aa aa
a Aa aa
F1) 2/4 = 1/2 = 50% Aa, Plant with Green pods
2/4 = 1/2 = 50% aa, Plant with Yellow pods
