Answer:
Ss × ss
Explanation:
This question involves a single gene coding for hair length in guinea pigs. The alleles for short hair (S) is dominant over that of long hair (s).
According to this question, a guinea pig with short hair (S_) is crossed to one that has long hair (ss) to produce offsprings that have 44 short hair and 46 long hair. This number of offsprings produced indicate a ratio of 1:1, which can only be produced if the short haired guinea pig is heterozygous i.e. Ss.
Therefore, the genotype of the parents are Ss (short hair) and ss (long hair) i.e. Ss × ss. This combination will produce offsprings with the following proportion: Ss (1) : ss (1).
Explanation:
Type II restriction enzymes are the familiar ones used for everyday molecular biology applications such as gene cloning and DNA fragmentation and analysis. These enzymes cleave DNA at fixed positions with respect to their recognition sequence, creating reproducible fragments and distinct gel electrophoresis patterns. Over 3,500 Type II enzymes have been discovered and characterized, recognizing some 350 different DNA sequences. Thousands more ‘putative’ Type II enzymes have been identified by analysis of sequenced bacterial and archaeal genomes, but remain uncharacterized.
Answer:
White-tailed deer, mice, chipmunks, gray squirrels, opossums and raccoons
Explanation:
All of these can play a role in prevalence of Lyme disease.
Answer: Mouse
Explanation: Because a snake is a carnivore, it does not make sense for a snake to eat berries. However, by adding a mouse between berries and snake, the food chain will make sense.
