In fruit flies long wings are a dominant trait and short wings are recessive trait Two fruit flies that are heterozygous for the long wings trait mate the cross produces 180 offspring how many are we expected to have short wings

45.

Explanation:

Lets say

X= dominant, long wings

x= recessive, short wings

Using Punnett Squares

Xx = heterozygous

Alleles            X           x  

X                   XX         Xx

x                    Xx          xx

Out of 4, only 1 has both recessive short wings, so using the ratio 1/4 × 180 offsprings, 45 of them are expected to have short wings.

interphase   is the cell cycle stage in which the cell acquires nutrients, creates and uses proteins and other molecules and starts the process of cell division by replicating the dna. it is the longest stage in the eukaryote cell cycle.

the following   can go wrong during interphase:   a base pair could be mismatched during the duplication process causing a mutation.   correct answer: c

explanation:

c: warm water flows from the western tropical pacific toward south america. that should be the right answer! hope it .
