<span>Science of Biology is the study of using evidence
to learn about the natural world. Scientists use this body of knowledge to
gather data, both quantitative (numbers) and qualitative (descriptive), and
propose scientific explanations based from scientific experiments. The goal of
science is to basically deal with the natural world; collect and organize the
necessary information; and eventually propose explanations that can be tested. </span>
<span>
Science therefore is an ongoing process and will
continue and is a bridge to satisfy our human thirst for knowledge. </span>
Answer:
c. All eight possible phenotypes could occur, but a greater proportion of the offspring would have the parental phenotypes
Explanation:
When genes are linked they do not assort independently. Instead, the alleles on the parental chromosome will have a tendency to migrate together to the same pole of the cell. To produce gametes with genotypes different than the parentals crossing over must happen between the genes of homologous chromosomes during meiosis. However, recombination is a rare event, so the recombinant gametes will be less frequent than the parentals (those that arise when no recombination occurs between genes) and for that reason a greater proportion of the offspring will have parental phenotypes.
<span>During the development of
a gamete, the two alleles of the P generation separate. Each gamete carries one allele from each
parent which randomly pairs in the F1 generation. This mechanism repeats when
F1 plants cross and yield F2 plants. The
outcome of the F2 generation would then have new combinations of alleles which
can be different compared to the preceding generations.</span>
Answer:
Protection
Explanation:
Most cells have wall cells to protect the cell including bacterias.
It’s the last two (C and D) that may induce a chromosomal mutation
