Answer:
Every population experiences genetic drift, but small populations feel its effects more strongly. Genetic drift does not take into account an allele's adaptive value to a population, and it may result in loss of a beneficial allele or fixation (rise to 100% frequency) of a harmful allele in a population.
Explanation:
The recessive trait is small teeth
Answer:
33.3 cM
Explanation:
Parent 1: blue shell, long antenna : BBLL
Parent 2: green shell, short antenna : bbll
BBLL X bbll :
F1 : BbLl ( blue shell, long antenna )
BbLl X bbll :
BL/bl = 82 : Parental
bl/bl = 78 : Parental
Bl/bl = 37 : Recombinant
bL/bl = 43 : Recombinant
Total = 240
Recombination frequency = (Number of recombinants/ Total offspring)*100
= (80/240) * 100 = 33.33 %
Map distance = recombination frequency
Hence, map distance = 33.3 cM
C because we are testing the effectiveness of Fertilizer X and Y and using no fertilizer can help determine if that would be better than using a fertilizer. Additionally, a control group of no fertilizer would be the third plant as that is considered normal for the experiment. Msg me for any more questions
