Answer:
- Alelos:
Locus 1: A (alto); a (enano)
Locus 2: B (púrpura); b (blanco)
- Cruzamiento parental: AABB x aabb
Genotipos F1: AaBb
- Cruzamiento F1: AaBb x AaBb
Fenotipo: 100% plantas altas púrpuras
- Genotipos F2: AABB (1/16); Aabb (1/16); aaBB (1/16); aabb (1/16); AaBb (4/16); AABb (2/16); aaBb (2/16); AaBB (2/16); Aabb (2/16)
- Fenotipos F2: 9/16 A-B- (altas púrpuras); 3/16 A-bb (altas blancas); 3/16 aaB- (enanas púrpuras); 1/16 aabb (enanas blancas)
Explanation:
Un cruzamiento dihíbrido refiere a un tipo de cruzamiento entre dos parentales que difieren para dos pares de alelos (AABB x aabb). Si consideramos dos loci de dominancia completa, un cruzamiento dihíbrido producirá una F1 heterocigota para ambos genes donde la progenie expresará ambos rasgos dominantes. Como resultado de la distribución independiente expresada en la segunda ley de Mendel, La F2 de este tipo de cruzamiento producirá un proporción fenotípica 9:3:3:1; es decir 9 individuos con ambos rasgos dominantes (A-B-), 3 con el rasgo uno dominante (A-bb), 3 con el rasgo dos dominante (aaB-) y 1 con ambos rasgos recesivos (aabb).
What are the phenotypes of an organism?
A. the organism's genes
B. the organism's physical traits
Answer:
A.
Explanation:
The term "phenotype" refers to the observable physical properties of an organism; these include the organism's appearance, development, and behavior. An organism's phenotype is determined by its genotype, which is the set of genes the organism carries, as well as by environmental influences upon these genes.
Answer:
A. the organism's genes
Explanation:
The phenotypes of an organism are the genes carried by the organism.

Why didn’t Darwin understand that genetics has passed on.
Answer:
Darwin did not know that DNA would become an important part of his Theory of Evolution. In fact, the subcategory of evolution called microevolution is completely based on DNA and the mechanism of how genetic information is passed down from parents to offspring.
Explanation:
DARWIN'S DIFFICULTIES WITH BLENDING INHERITANCE AND HIS THEORY OF PANGENESIS. Darwin failed to understand the significance of these results because he had no model of particulate inheritance that could be applied to genetic data.

Explain in at least five sentences what you've learned about how
global warming and climate change are impacting our Earth in different regions of the world.
Explanation: I'd first address the issue as a whole and explain the meaning and the general impacts of climate change, then use a variety of different places. For example, global warming causes the ice caps to melt in Antarctica. Then, explain how this has an impact on the environment meaning that polar bears could be in life-threatening situations and possibly even become extinct in the future which has a further impact on other animals in that food chain and ecosystem. This is just one example. You could also explain the unbearable heat in countries nearer the equator, which prevent crops from growing; the sea levels rising; or extreme weather events like huge flooding or heatwaves. It depends what you have learnt about in class, but I'm assuming it would be about this sort of thing.
Answer:
Higher death rates. ...
Dirtier air. ...
Higher wildlife extinction rates. ...
More acidic oceans. ...
Higher sea levels.

"I don't get it. Why do I need to learn about meiosis to understand about variation in a species?" moaned Trina. How would you explain to her what the relationship is between the two?
Answer:
The cell division that halved the no. of chromosomes is the meiosis. The meiosis takes place during formation of gametes (eggs & sperms) in higher organisms. eggs & sperms posses only one chromosomes of each pair of chromosomal set. (2n➡️n).
When these gametes fuse to form the zygite, the chromosomes become n+n➡️2n again.

Describe movement of molecules to maintain a healthy cell environment. Explain in details
Answer:
Very necessary for its survival.
Explanation:
Movement of molecules is very important to maintain a healthy cell environment because some molecules are required by the cell for its growth and development. Some molecules moves inside the cell environment through a semi-permeable membrane such as glucose, oxygen, potassium etc while on the other hand, some molecules are removed from the cell which are waste materials such as carbondioxide etc. If these waste materials are not removed from the cell, it greatly damaged the cell.

A Russian citizen has illegally obtained a Siberian tiger and is trying to sell the tiger’s fur in the United States. What treaty does this violate?
A.Tiger Treaty
B.Lacey Treaty
C.CITES
D.EPA
Answer:
Cites,
Explanation:
Another Answer on Brainly
The treaty that the Russian citizen violated is CITES or Convention on International Trade in Endangered Species. The treaty was drafted from 1973 in order to protect the over - exploitation of wildlives.
A Russian citizen has illegally obtained a Siberian tiger and is trying to sell the tiger’s fur in the United States, CITES treaty does this violate. Therefore, the correct statement is option C.
What is CITES?CITES, or the Convention on International Trade in Endangered Species of Wild Fauna and Flora, is the treaty that this action would break. Since Siberian tigers are considered an endangered species, the Convention on International Trade in Endangered Species (CITES) regulates international trade in their parts or products.
A violation of CITES regulations is the illegal possession, sale, or transportation of an endangered species or its parts or products, like fur, without the necessary permits or documentation.
The Lacey Act is a US regulation that denies the exchange unlawfully got natural life, plants, and their items, yet refers to a worldwide settlement that oversees the exchange of jeopardized species across borders. The United States Environmental Protection Agency (EPA) is in charge of enforcing environmental laws.
Therefore, the treaty that this action would violate is CITES (Convention on International Trade in Endangered Species of Wild Fauna and Flora).
