On a phylogenetic tree, which term refers to lineages that diverged from the same place?
Elden [556K]

Answer:

sister taxa

Explanation:

Groups departing from the same evolutionary node are called sister taxa and are evolutionarily closer to each other than groups departing from another node. Thus, we can say that the sister taxa are evolutionarily closer (related) to each other than to the taxa that did not diverge from the same place. Similarly we can say that taxa that did not diverge from the same place, cannot be called sister taxa and are distant evolutionary.

In a hypothetical population of plants, flower color is determined by a single gene with two alleles. In a population of 500 pla
blondinia [14]

Answer:

In the F1 generation

RR = 0%

Rr = 50% (or 0.5)

rr = 50% (or 0.5)

Explanation:

A pink flowering plant has the genotype Rr. It is heterozygous for the allele. The alleles for this gene appears to show incomplete dominance, as the heterozygous phenotype is a blend of the two homozygous genotypes.

A white flowering plant has the genotype rr. It is homozyogous for the white allele

A punnet square of the cross is shown.

The resulting punnet square shows that only Rr and rr genotypes are possible, at a ratio of 50:50 (or 1:1). Therefore, the genotype frequency of Rr is 50%, and rr is 50% in the F1 generation. This can also be written as 0.5. It is not possible to get a red plant, as the genotype RR can not come from this cross

trasher [3.6K]

Earth is a beautiful planet that revolves around a star called Sun, which is located in one of the arms of our Milky Way Galaxy. It is the only planet known to support life in the Solar System. Humans are the most intelligent civilization on this planet. It's blue when seen from space. Recently, Earth 29 spacecraft was able to land on this planet, after 28 unsuccessful landings of Earth series of spacecrafts. We were able to learn many things about humans, most important of these was the most spoken language of them, which they call English. According to experts, humans are not yet ready to know about our existence. It can take about 1 or 2 more centuries, until they are ready to know about us.

How does extinction affect evolution?
Semenov [28]
If a species is said to be extinct, then that species is reduced to zero. There are none living in existence. The affects to other organisms of its extinction would depend on their value to the ecosystem. Regardless, extinction completely stops evolution of the species extinct.
