erastova [34]

Answer:

22 mu

Explanation:

Since maximum number of flies are observed with +pb and s++ phenotype, they are the parental combinations.

Minimum number of flies are observed with +p+ and s+b phenotype hence they are the result of double crossover.

Gene order would be +bp and s++ since it is the only case which would lead to production of above mentioned double crossover. Hence gene b is in the middle of genes s and p.

Single cross over between genes s and b will give progeny +++ and sbp.

Map distance between s and b loci = recombination frequency =

(number of recombinants/ total progeny)*100

= [(single cross over between s and b + double crossover)/total progeny]*100

= [(102+106+7+5/1000]*100

=(220/1000)*100

=0.22*100

=22 mu

La diferencia entre geocentrico y heliocentrico​
slamgirl [31]

Answer:

Explanation:

English-The geocentric model says that the earth is at the center of the cosmos or universe, and the planets, the sun and the moon, and the stars circles around it. The early heliocentric models consider the sun as the center, and the planets revolve around the sun.

Spanish-El modelo geocéntrico dice que la tierra está en el centro del cosmos o universo, y los planetas, el sol y la luna, y las estrellas giran a su alrededor. Los primeros modelos heliocéntricos consideran al sol como el centro y los planetas giran alrededor del sol.
