While working in a genetics lab over the summer, you isolated a true-breeding strain of wingless drosophila. after sharing your

results with your mentor, you learn that six other true-breeding strains of drosophila with the same mutant phenotype have been isolated independently in your lab. your mentor asks you to determine if the mutants belong to the same complementation group. what is true about flies that belong to the same complementation group? what would be the outcome of crossing two strains of wingless flies that belong to the same complementation group? select all answers that apply to the two questions?

Answer:

If the two mutations are on different genes, mating together, the progeny will have the function restored.else if the mutation is the same, the function shall remain and wingless progeny will be visible.

Explanation:Just to explain shall use an example.Suppose there are two different mutations . The genes be called as 1 and 2.Also assume that they make proteins 1 and 2.Now the two proteins shall perform two different functions but the end wingless character is maintained.Now suppose fly 1 has mutation 1 and protein 1 is not being synthesized .But yet it is being synthesized in fly 2, that has a mutation in protein 2.when the two are mated protein 1 comes from fly 2 and protein 2 comes from Fly 1, as a result the two proteins and their functional copies are available and hence all functions completed and the fly develops a wing.The essential thing to understand is that if two flies have two different mutations both will have the two proteins from the other fly and the function of the protein will be completed.

nekit [7.7K]

Answer:

C

Explanation:

Assume that allele A is the dominant allele that produces the dominant phenotype (tall) in plants that have at least one allele A, and allele a is the recessive allele that produces the recessive phenotype (short) in plants that have two alleles a.

In the parental generation, a true-breeding tall plant has the AA genotype (phenotype: tall), and a true-breeding short plant has the aa genotype (phenotype: short).

We have the Gregor Mendel's cross as in the image attached here.

All of the F1 generation (offspring plants) have the Aa heterozygous genotype, and therefore, they are all tall.

The answer is c (the offspring plants have a genotype that was different from that of both parents).

Traditional ecological knowledge is A. rarely shared in local languages B. not well known in the West because some species and e
Alex73 [517]

Answer:

Option-C

Explanation:

Traditional ecological knowledge is the knowledge acquired and adapted by the local or native people living in a particular area.

The traditional knowledge is gained by the holistic approach of gaining the knowledge that is which benefits survival and increases the chances of well being.

The approach aims at learning by making direct contact with the surrounding environment, learning its ways, understanding the relationship between the various factors and then adapting to the condition and utilizing the available information.

The traditional way aims at looking at the environment in whole but the modern way of understanding the environment aim by learning the environment in the components.

The traditional knowledge is always shared by the local people in their local language but since the ideology of gaining the knowledge differ in both the ways and TEK is shared in local language therefore sometimes the knowledge does not prove useful in the contemporary world.

Thus, Option-C is correct.

4- Jamie does an experiment. She charges a pencil by rubbing it with a piece
lyudmila [28]

Answer:

More info given below.

Explanation:

This attraction occurs as a result of static charge. You see an atom is referred to as the smallest particle of a substance; and when an atom gains or looses electrons it becomes unstable creating a difference in potential. However in this case rubbing induces friction which induces heat. This heat excites the atom to loose electrons creating a negative charge on the silk and a converse positive charge on the pencil.
