If 1000 f2 offspring are obtained, how many flies of each phenotype are expected?
aniked [119]
<span>In Drosophila + indicates wild-type allele for any gene, m is mahogany and e is ebony. Female parents are m+/m+ and males are +e/+e. F1 are m+/+e, all wild type. F1 females are crossed with me/me males - the test cross. Offspring will be : non recombinant m+/me, mahogany wild type or +e/me wild type ebony. OR recombinant me/me mahogany ebony or ++/++ wild type. As the two genes are 25 map units apart, the percentage of recombinants will be 25% and therefore percentage parental types will be 75%. 75% 1000 is 750. There are two parental types, so you would expect 375 of each. Therefore, you would expect 375 m+/me and 375 +e/me. 25% of 1000 is 250 split between two recombinants =125 of each. Therefore you would expect 135 me/me and 125 ++/++</span>

Does geographic distance between salamander populations increase their reproductive isolation? To answer this question, research
Nataly_w [17]

Question: Does geographic distance between salamander populations increase their reproductive isolation?  To answer this question, researchers studied populations of the dusky salamander (Desmognathus ochrophaeus) living on different mountain ranges in the southern Appalachian Mountains.  The researchers tested the reproductive isolation of pairs of salamander populations by leaving one male and one female together and later checking the females for the presence of sperm. Four mating combinations were tested for each pair of populations (A and B)—two within the same population (female A with male A and female B with male B) and two between populations (female A with male B and female B with male A).  The proportion of successful matings for each mating combination was measured. For example, when all the matings of a particular combination were successful, the researchers gave it a value of 1; when none of the matings were successful, they gave it a value of 0. Then the researchers calculated an index of reproductive isolation that ranged from 0 (no isolation) to 2 (full isolation). The reproductive isolation value for two populations is the sum of the proportion of successful matings of each type within populations (AA + BB) minus the sum of the proportion of successful matings of each type between populations (AB + BA).

The table (Figure 1) provides data for the geographic distances and reproductive isolation values for 27 pairs of dusky salamander populations.

Part A - Understanding experimental design

What hypothesis did the researchers test in this study?

Answer:

"Reproductive isolation increases with geographic distance between dusky salamander populations"

Explanation:

The mechanisms of reproductive isolation are a assemblage of evolutionary mechanisms, behaviors and physiological procedures dangerous for speciation. They avert followers of dissimilar types from manufacturing offspring, or confirm that any offspring are germ-free. While in allopatric speciation the reproductive isolation is resolute superficially by the spatial isolation of populations, during sympatric speciation specific groups of persons create distinct mating organizations with self-like persons while distribution the similar home with the rest of the unique inhabitants.

Which property would be classified as expendable?
Andrej [43]
Expendable properties are those properties that are consume in use or that lose their identity in use. It also include those properties that become an integral part of other property when put to use and those properties which have an expected service life of less than one year. One example of expendable properties is materials and supplies given to an army unit.
