The law of segregation states that allele pairs separate during gamete formation. How then do we have two alleles for a trait?
Ivahew [28]
It’s not so much that the alleles separate but more so that only one of the parental alleles is passed on. Let’s look at a monohybrid trait to make this easier to comprehend, and let’s say the trait is eye color. One of the parents has blue eyes, a recessive eye color, meaning both of their alleles for that trait are recessive. However, the other parent has brown eyes, a dominant eye color, meaning this parent could either possess one dominant allele that hides the recessive blue (let’s just limit it to two colors to avoid confusion) or they could have two dominant alleles. When gametes are formed, they consist of a combo of alleles, one maternal and one paternal. Meaning, in the case of the heterozygous dominant parent (or the parent with one dominant and one recessive allele) they could either pass on their dominant allele, giving the child brown eyes, or their recessive allele, giving the child blue eyes because they can only ever inherit the recessive trait from the other parent. The law of segregation essentially says that a parent cannot clone itself and create a child in its exact image but rather that the child would inherit one trait from each parent. This is why the child has two alleles for the trait and the parents both have two alleles for this trait. Hope this helps (:

The Suillus lakei mushroom is commonly found
Oksi-84 [34.3K]

Answer:

Suillus lakei mushroom refers to a mycorrhizal fungus, which grows in company with Douglas fir, and can be witnessed in the locations where this tree is found.  

This association illustrates a symbiotic relationship, known as mycorrhizae, which is produced between the plant and the fungi. The fungi colonize the root system of the host plant, in this case, Douglas fir, and provide enhanced nutrient and water absorption tendencies, while the plant offers the fungus with carbohydrates produced from the process of photosynthesis.

What is one main purpose why some bacterial species produce endospore?
kotykmax [81]

Answer:

'It allows the bacterium to produce a dormant and highly resistant cell to preserve the cell's genetic material in times of extreme stress. Endospores can survive environmental assaults that would normally kill the bacterium.'

Below is a sequence from a template strand of DNA. Write the sequence of the mRNA that would be transcribed from this. Be sure t
Ksju [112]

Answer:

In the transcription of DNA to mRNA, for the DNA sequence 3'-AGGTCTCAC-5' corresponds to an mRNA sequence 5'-UCCAGAAGUG-3'.

Explanation:

Transcription is the process by which a strand of mRNA, needed to direct protein synthesis in the cytoplasm, is synthesized from a strand of DNA.

The sequence of nucleotides in the RNA chain depends on the sequence of bases in the DNA strand, being placed according to the complementarity of nitrogenous bases, where a purine is complemented with a pyrimidine.

In RNA, the thymine base is replaced by Uracil, the complementary base to adenine of DNA.

<u>ADN   mRNA</u>

A            U

T            A

C            G

G            C

For this reason:

<em>DNA:​​</em><em>    3’ A G G T C T T C A C 5’</em>

<em>mRNA:</em><em> 5'-U C C A G A A G U G-3'</em>
