vova2212 [387]

Answer:

A) The two genes are unlinked and are assorting independently, leading to a 1:1:1:1 ratio of phenotypes in the offspring.

Explanation:

The χ2 value means nothing on its own--it is used to find the probability that, assuming the hypothesis is true, the observed data set could have resulted from random fluctuations. A low probability suggests the observed data is not consistent with the hypothesis, and thus the hypothesis should be rejected. The hypothesis that you are testing are two genes are unlinked and are assorting independently, leading to a 1:1:1:1 ratio of phenotypes in the offspring.

<u>The four types of interactions in communities are:</u>

  • Mutualism
  • Parasitism
  • Commensalism
  • Competition

<u>Definition of each interaction:</u>

<em>Mutualism: </em>

The type of interaction in which both the species involved are benefited, it is called mutualism.

<em>Parasitism:</em>

The type of interaction in which one species is benefited, whereas the other is harmed, it is called parasitism.

<em>Commensalism:</em>

The type of interaction in which one species gets benefited without harming or providing benefits to others is called commensalism.

<em>Competition:</em>

The type of interaction in which both species lose is called competition. It is opposite of mutualism.

<u>Symbiotic relationship:</u>

It refers to the type of interaction in which lastly one species gets benefited. The type of interactions such as <em>mutualism, commensalism, and Parasitism </em>are considered as symbiotic relationship.

How does mutation enable viruses to continue causing disease?
Hunter-Best [27]
Genetic Change in Viruses. Viruses are continuously changing as a result of genetic selection. They undergo subtle genetic changes through mutation and major genetic changes through recombination. Mutation occurs when an error is incorporated in the viral genome

QUESTION 31 Chipmunk mitochondrial DNA was fingerprinted using the single primer amplified region technique (SPAR) and the PCR r
natima [27]

Answer:

It depends on the size of the amplified DNA fragments (for example for SPAR markers consisting of 200 bp in length >> 1600 / 200 = 8)

Explanation:

The PCR based single primer amplification reaction (SPAR) methods are tools for detecting genetic diversity by using DNA markers such as Simple Sequence Repeats (ISSRs), Minisatellite DNA regions (DAMDs) and Random Amplified Polymorphic DNAs (RAPDs), which can be used alone or combined with each other. In the last years, the SPAR methods have gained attention in the scientific community because they are cost-effective and highly effective for the detection of both intraspecific and interspecific genetic variation. In the SPAR methods, the size of the bands will depend on the length of the amplified DNA fragments.
