Answer:
- 4 out of 16 guinea pigs would have white hair.
- 12 out of 16 guinea pigs would have short hair.
Explanation:
This question involves two genes. One coding for hair color and the other for hair length in guinea pigs. The alleles for black and white hair are B and b respectively while the alleles for short and long hair are S and s respectively.
Based on this question, two parents that are heterozygous for both genes (BbSs) are crossed (as seen in the attached punnet square). The guinea pigs that have an allelic pair of bb have white hair while those that have an allelic pair of SS or Ss have short hair as described in this question.
Using the punnet square attached,
- 4 out of 16 guinea pigs would have white hair because 4 offsprings possess the genotype bb for the first gene.
- 12 out of 16 guinea pigs would have short hair because 12 offsprings possess the genotype SS or Ss for the second gene.
Answer:
It explains how organelles and eventually eukaryotic cells could have arisen
Explanation:
Answer:
Because most natural environments harbor a stunningly diverse collection of microbial species. Within these communities, bacteria compete with their neighbors for space and resources. Laboratory experiments with pure and mixed cultures have revealed many active mechanisms by which bacteria can impair or kill other microbes. Additionally, a growing body of theoretical and experimental population studies indicate that the interactions within and between bacterial species can profoundly impact the outcome of competition in nature. The next challenge is to integrate the findings of these laboratory and theoretical studies, and to evaluate the predictions they generate in more natural settings.
