A scientist has an uncharacterized pea plant. She wants to determine the plant’s genotype for seed color. In order to be certain
aleksklad [387]

Answer:

Recessive phenotype plant

Explanation:

If the plant has recessive genotype then it will be easy to identify because it will have the recessive phenotype. However if the plant has dominant phenotype it can either have homozygous genotype or heterozygous genotype. To confirm if the plant is homozygous or heterozygous, a test cross can be done with plant having recessive phenotype.

If our test plant is homozygous dominant, it will pass one dominant allele to the next generation and all the offspring would have dominant phenotype. If our test plant is heterozygous dominant it will pass one dominant allele to half of the offspring and one recessive allele to another half so 50% of next generation will have dominant phenotype and other 50% will have recessive phenotype.

Hence by test cross (cross with recessive phenotype plant) it is possible to determine the genotype of the uncharacterized pea plant.

scoundrel [369]
The post mortem interval of a body enclosed in a plastic bag could be best estimated by the insects found in the body, in that case forensic science need to listen to what those little creatures have to say, insects could tell if the body has been moved from the crime scene, how long it´s been in an specific place, and how long it´s been since death until found, every group of insects can tell something different, from worms, arachnids to flyes, each one of them has a time to get into the body, so it could tell you for how long it´s been dead.

Sort the statements based on whether they describe DNA replication in eukaryotes or prokaryotes. Replication takes place in the
Ilya [14]
In eukaryotes, <em>replication takes place in the nucleus</em> as prokaryotes do not have a true nucleus and <em>replication takes place in the cytoplasm</em>. The nucleus of the eukaryotes is the location where genetic material (DNA) is found; in prokaryotes, the genetic material is condensed in the cytoplasm called the nucleoid. There are multiple replication forks or <em>multiple origins of replication </em>in eukaryotes in contrast to prokaryotes which only has <em>one origin of replication. </em>Lastly, replication in eukaryotes <em>occurs at multiple points along the chromosome; </em>in contrast with prokaryotes where it <em>occurs at just one point on the chromosome.</em>
