I need help with the image (phenotypes and genotypes).

Biology
1 answer:
Flauer [41]3 years ago
5 0

Answer:

See the answer below

Explanation:

1. <u>Only one phenotype</u> is present in the F1 generation offspring. Since tallness was dominant over shortness, all the offspring in the F1 generation appeared tall.

2. <u>Two phenotypes </u>are present in the F2 generation - 9 tall and 3 short. The short trait reappeared at the F2 generation.

3. The genotype of the F1 offspring would be heterozygous. Assuming the purebred tall is AA and the purebred short is aa:

     AA   x   aa

  Aa   Aa   Aa   Aa

All the F1 offspring will appear tall and their genotypes would be heterozygous.

4. Assuming that the allele for height is denoted with A (a), <u>the genotype of the purebred tall plant would be AA. </u>

5. In a similia vein, <u>the genotype of the purebred short plant would be aa. </u>

predict if the sensory nerves in a persons foot are nonfunctional, would the person feel pain if the foot was severely burned
irina1246 [14]
Nerves are cells that can detect any type of pressure, movement, or anything of that nature. If we didn't have nerves, we couldn't feel pain. If the nerves in a foot are damaged, you wouldn't feel the pain of it being burned.

The molecular clock has limited usefulness for estimating divergence times among species in part due to the saturation of DNA se
Greeley [361]

<u>Answer:</u>

<em>In highly diverged lineages, the substitutions process will occur at sites that have been substituted previously</em>.

<u>Explanation:</u>

Molecular clock uses the mutation rate to reduce the time in prehistory when the life forms are diverged. <em>The molecular clock uses the sequence of amino acids and nucleotide sequence for the DNA.</em>  

This clock does not measure any time but the number of mutations, and other changes over certain time.  <em>Sometimes its useful property might be limited due to the highly diverged lineages.</em>

Environmental microbiology... A. ...shows great promise, but has not yielded any significant discoveries yet. B. ...includes met
Sveta_85 [38]

Answer:

B. ...includes methods like metagenomics, which sequence and interpret all the DNA in an environmental sample.

Explanation:

Environmental microbiology is the science in charge of the study of microorganisms, small living things known as microbes. Study organisms that are only visible through a microscope, such as prokaryotic and simple eukaryotic organisms.

Metagenomics is the study of a collection of genetic material from a mixed community of organisms. Metagenomics usually refers to the study of microbial communities. It is generally used when studying microbial communities in which one microorganism cannot be separated from another.

Assuming DNA is replicated correctly (so there are no mutations),
gavmur [86]

Answer:

None of the choices would lead to all identical gametes.

Explanation:

Gametes are sex cells produced by sexually reproducing organims via a process of cell division called MEIOSIS. Meiosis is a cell division process which produces four (4) daughter cells (gametes), which are genetically different from the parent cell.

The difference in genetical content is as a result of a process unique to only meiosis called CROSSING-OVER OR RECOMBINATION. This process ensures that the genetic content of the gametes are altered. Hence, since gamete formation is done via meiosis, none of the scenarios in the option will lead to all identical gametes.
