After crossing over as shown below what would the sequence of genes be for each of the chromatids

Biology
1 answer:
SashulF [63]3 years ago
8 0

The sequence of the genes will be ABCD, abCD and abCd, abcD.

Full question is attatched below.

<h3><u>Explanation:</u></h3>

The genes in the chromosomes are denoted as the sequence of genes present in a single chromatid of a particular chromosome. Thus, the genes here in this question are to be mentioned as ABCD and not as abab.

Crossing over is the process by which the homologous pair of chromosomes do pair up in the Prophase 1 of meiosis 1 division and they exchange a particular part of their DNA with each other. This leads to exchange of genes between the homologous chromosomes, which will form different gametes in near future. This brings about a variation between the offsprings of same individuals.

Here the d gene of the two chromosomes are getting exchanged.

So the chromosomes will become ABCD, abCD and abCd, abcD respectively.

How would a tsunami most likely affect the abundance of aquatic organisms in the intertidal zone of the ocean?
AlexFokin [52]

Answer: C). A tsunami would decrease abundance by causing physical damage to the organisms and their ecosystems.

An intertidal zone is also known as littoral zone. It is the region which is covers the foreshore and seabed. This region is exposed to the affects of tides. This region is highly vulnerable to tsunamis. The tsunami will disturb the habitat of organisms living in intertidal zone. Therefore, will result in decrease in abundance of aquatic organisms.

Anthony places a drop of water under a microscope and observes some small objects. He concludes that the small objects are cells
natta225 [31]

Answer:

It depends on the lens of the Anthony´s microscope, but It is likely that he saw artifacts

Explanation:

An optical microscope contains lenses of focal lenght that enable to see different structures. In this case, it is likely that Antony saw artifacts since living cells are not easy to focus with the optical microscope, it requires operator experience

If 1/8 remains after 21 years, what is the half-life?
vagabundo [1.1K]

Half life formula

The number of unstable nuclei remaining after time t can be determined according to this equation:

N(t) = N(0) * 0.5^(t/T)

where:

N(t) is the remaining quantity of a substance after time t has elapsed.

N(0) is the initial quantity of this substance.

T is the half-life.

It is also possible to determine the remaining quantity of a substance using a few other parameters:

N(t) = N(0) * e^(-t/τ)

N(t) = N(0) * e^(-λt)

τ is the mean lifetime - the average amount of time a nucleus remains intact.

λ is the decay constant (rate of decay).

All three of the parameters characterizing a substance's radioactivity are related in the following way:

T = ln(2)/λ = ln(2)*τ

How to calculate the half life

Determine the initial amount of a substance. For example, N(0) = 2.5 kg.

Determine the final amount of a substance - for instance, N(t) = 2.1 kg.

Measure how long it took for that amount of material to decay. In our experiment, we observed that it took 5 minutes.

Input these values into our half life calculator. It will compute a result for you instantaneously - in this case, the half life is equal to 19.88 minutes.

If you are not certain that our calculator returned the correct result, you can always check it using the half life formula.
