Answer:
Cuando dos organismos comparten un ancestro común, su código genético tiene que ser similar. El grado de similitudes determina qué tan recientemente han evolucionado los organismos. ... Cuando dos organismos tienen una anatomía muy similar, podrían haber descendido de un ancestro común
Explanation:
Answer:
This is due to the event of Speciation that happened for the rodents in Island B but not for the rodents in Island C.
Explanation:
- Due to splitting of the population,
- The sub-population of rodents formed in Island B are B1 and B2.
- The sub-population of rodents formed in Island C are C1 and C2.
- In case of Island B, each of the B1 and B2 sub-populations that got split from each other developed certain mutations that were necessary for them to adapt to the particular diverse environment each of them were exposed to, through the period of 50,000 years. These mutations were so varied that reproductive isolation was generated between them that resulted in each of them to develop into different species.Hence, speciation happens here and B1 and B2 are incapable of inter-breeding.
- In case of Island C, each of the C1 and C2 sub-populations that got split might have got exposed to similar environmental change or no environmental change or the environmental change might have been too small to cause drastic change in each of the sub-populations. As a result of this the two sub-populations might have acquired certain mutations to adapt to the environment each of them were exposed to, through a period of 100,000 years. These mutations might not have been too variable or contrasting to cause reproductive isolation between C1 and C2. Hence, no new speciation happens here and C1 and C2 are capable of inter-breeding.

Answer:
The statements which are correct are:
-85% of the U.S. corn is GMO; modified to be resistant to herbicides.
-Technology now allows us to transfer genes between organisms of different species and even kingdoms.
- Extensive testing has been conducted on GMO-foods to ensure that there will be no adverse allergic reactions or health risks.
Explanation:
GM foods can be described as the food which is genetically modified. In simpler terms, food prepared by the introduction of a foreign gene is termed as genetically modified food.
About 92 percent of the corn produced in the U.S is genetically modified and out of it about 85 percent is genetically modified to be resistant against herbicides.
The use of GM foods was made legal after passing through various tests in the laboratory and being approved by the FDA. Up till now, any food prepared by this method is properly tested and approved By FDA before introducing it into the market.
Answer:
The correct answer is option B. has a defective allele and normal phenotype.
Explanation:
Genetic carrier or the hereditary carrier is an organism or a person that has a recessive allele for a particular trait or character (generally mutation) but does not exhibit the trait or any character related to the trait.
The carriers are normal in the sex-linked characters in comparison to the autosomal traits. Females are generally the carrier for sex-linked characters and carry the allele to the next generation.
Thus, the correct answer is option B. has a defective allele and normal.
