The answer is C Multiple alleles for feather color are present in the population.

An allele is one of two or more alternative forms of a gene. Since f<span>eather color in a bird was traced to a single gene, the trait is a monogenic and not a polygenic trait (choice b drops off). Further, there are 6 variations of feather color which are  controlled by <em>one gene</em>. That means there are 6 variations of the gene. And since the alleles are alternative forms (or variations) of the gene, there are 6 different alleles for feather color.</span>

Question 14 of 25
Archy [21]

The process likely to be occurring in the plant's roots will be nitrogen fixation.

<h3>What is nitrogen fixation?</h3>

It is a process whereby atmospheric nitrogen is converted to usable forms of nitrogen in the soil.

Nitrogen fixation takes place in the root nodules of leguminous plants in association with some symbiotic bacteria.

Thus, the only process that could be happening in the plant's root is nitrogen fixation.

Reproduction by mitosis duplicates:A. chromosomesB. genesC. DNAD. all of the above
Montano1993 [528]

I do not understand why this was deleted, but Reproduction by mitosis duplicates all of the above, because all of these are in the gene being duplicated, the chromosomes, the gene itself, and the DNA.

Hope this helps, if not, comment below please!!!!

3. During which process do alleles undergo segregation? (1 point)DNA replication. mitosis. meiosis. transcription. .
valentina_108 [34]
3. The answer to your question is B. Meiosis. Alleles undergo segregation during meiosis. The alleles will split into 2 daughter cells; one chromosome for each cell. 4. The answer is homologous chromosomes. Gametes have homologous chromosomes. A gamete is a mature haploid cell. It can either be a male or female gamete. Each haploid cell will unite with another haploid cell of the opposite gender for reproduction. 5. The answer is B. IBi or IBIB. This demonstrates the genotype that corresponds to human blood type. <span>
