Answer:
Producing as many offsprings as possible so the chance of them living is higher.
Explanation:
Answer:
Contains large polytene chromosome that permit visual inspection of genomic events.
Were used to study the genetic effects of mutations.
Were used to establish the concept of chromosomal inheritance.
Explanation:
<em>Drosophila melanogaster </em>is a model organism that is used by scientists to study the genes and effect of a mutation on the genes. Drosophila is used as a model organism as it has a very short life cycle and the offspring can be produced in a short duration of time.
Because of these characteristics, Thomas Hunt Morgan wanted to study the factors of inheritance on the <em>Drosophila</em> and concluded in the form of the chromosomal theory of inheritance by the effect of mutation on genes that lead to linkage mapping.
Also, the salivary gland of fruit fly contains the polytene chromosome which allows us to look into the gene events.
Thus, the selected options are correct.
Answer:
White wool
Explanation:
The genotypes of every offspring will be Ww, making white dominant over black.
Answer:
B) aposematic coloration
Explanation:
The species constantly compete between each other, some because they occupy the same niche int he food chain, others even though they are in different niches tend to destroy each other, and some just avoid each other and partition the resources. This often results in partitioning of the resources between different species, when usually they are active in different parts of the day and avoid each other. Also, it is common that some of the species is more competitive, so that will result in a decline of the other species, or if the species are on the same level of competitiveness, then usually both species have declines in numbers to some optimal level. The aposematic coloration though is not part of the competition between the species. It is a type of coloration that warns the other species that the species that possesses it is either not good for eating, or it has a weapon that can harm them, thus they should avoid it and leave it alone.
