Answer:
The correct answer is - 3/16 or 18.75% portion will be resistant to both Bt and DDT.
Explanation:
It is given that bollworms that are susceptible to Bt are represented by either RR or Rr and resistance one are shown by rr genotype and bollworms that are resistant to DDT are represent TT or Tt genotype and susceptible to DDT have tt genotype.
Cross: RR tt with rr TT
Gametes: Rt and rT
F1 cross:
RT
rT RrTt ( susceptible Bt and resistant DDT)
F1 Cross with F1
Gametes: RT, Rt, rT and rt
cross:
RT Rt rT rt
RT RRTT RRTt RrTT RrTt
Rt RRTt RRtt RrTt RrTt
rT RrTT RrTt rrTt rrTt
rt RrTt Rrtt rrTt rrtt
The bold genotypes are the three out of 16 that are resistant to both DDT and Bt.
Answer:
an error in dna replication would affect many generations of cells
Explanation:
because DNA replication contains essentially all the genetic materials that will be needed in transcription and translation processes. And DNA replication is first step to ensure correct protein synthesis and others as well. But translation and transcription are both important to be exact, actually as incorrect transcription or translation could lead to useless proteins or etc.
9 atoms!!!!!!!!!!!!!!!!!!!!!!!
Answer: Oxygen
This is because after chloroplast produces the plants release oxygen (from production by chloroplast) to get rid of it. Making it essentially waste product
Answer:
25%
Explanation:
So there are 4 recessive alleles present for black fur on the square and there are also 4 dominant alleles. As there are the same amount of dominants as recessives the dominants will take over and be in control so the recessive alleles won't have as much of a chance
