The students performed a second cross the parental cross was between Nies that are true breeding for gray bodies and long wings and flies that are true breeding for ebony bodies and curly

wings. They crossed pairs of F, fies and determined the phenotypes of the resulting F ies. The students found an approximate 3:1 ratio of this with the dominant phenotype (gray bodies

and long wings) to ties with the recessive phenotype (ebony bodies and curly wings) only a few of the flies expressed the dominant phenotype of one trait and the recessive phenotype of the

other trait.

(a) In the first analysis, all of the F, Mies from the students' crosses have the identical phenotype with respect to body color and wing shape, but the F, flies have four different phenotypes

Describe how fertilization contributes to this genetic variability.

Which best describes meiosis? a. it produces cells that are identical to the original cell b. it is responsible for the replacement of damaged skin cells c. it is responsible for growth of the organism d. it produces male and female sex cells

If a baby girl guinea pig looks almost identical to its mother, does this then mean that it inherited more alleles from its mother? explain. (hint: think about the vocabulary words dominant and recessive.)

This map shows how climate change might affect precipitation patterns in the great plains of the united states by the end of this century. brown shoes a decrease in percipitation, and blue shows an increase. the maps differ based on the predictive levels of green house emissions. the maps shows that northern area should get a. more pracipations regardless of emmissions b. less pracipation, regardless of emmissions levels c. more precipitation, but only when emission levels.southern areas show a. more pracipations regardless of emmissions b. less pracipation, regardless of emmissions levels c. more precipitation, but only when emission levels.to use these maps to prepare for natural disasters in the great plains, scientist need to ask? a. how many tons of emissions were used at the basis of the map.b. which types of fossil fuels are used in the great plains c. if you think the above is wrong it's probly c the question is cut off
