Answer:
36 individuals xxyyzz
Explanation:
Available data:
X-Y = 20MUY-Z = 30MUCross: XXYYZZ x xyyzzF1= XxYyZzI = 40%2nd Cross: XxYyZz x xxYyzzF2 = 1000 individualsWe need to know how many individuals from the F2 are going to be xxyyzz
xxyyzz genotype is the result of a double recombinant event.
First, we need to analyze the given information:
→ Distances between genes
The genetic distance result from multiplying the recombination frequency of each region by 100 and expressing it in map units (MU). So, if we have the genetic distance we can divide it by 100 and get the recombination frequency:
Let us say that region I is the distance between X and Y. And region II is the distance between Y and Z.
GD = genetic distance
RF = Recombination frequency
GD (X-Y) = RF x 10020MU = RF x 100
20MU/100 = RF
0.2 = RF (Region I)
GD (Y-Z) = RF x 10030MU = RF x 100
30MU/100 = RF
0.3 = RF (Region II)
Now we have the recombination frequency of Region I and Region II.
→ Interference
Knowing the interference value will let us know the value of the coefficient of coincidence, which will also lead us to the number of individuals xxyyzz.
I = 40%
I = 1 - CC ⇒ CC = coefficient of coincidence
Clearing this equation gives us the value of CC
CC = 1 - I
CC = 1 - 40% = 1 - 0.4
CC = 0.6
To calculate the coefficient of coincidence, CC, we can also use the next formula:
CC = observed double recombinant frequency/expected double recombinant frequency
Now, we are interested in knowing the value of the observed double recombinant frequency.
Note:
observed double recombinant frequency = total number of observed double recombinant individuals/total number of individuals expected double recombinant frequency = recombination frequency in region I x recombination frequency in region II.So, to get the value of the observed double recombinant frequency, first, we need to get the value of the expected double recombinant frequency. And we can do it because we already have the recombination frequencies in both regions.
expected double recombinant frequency = recombination frequency in region I x recombination frequency in region II
- Recombination Frequency - RI = 0.2
- Recombination Frequency - RII = 0.3
expected double recombinant frequency = 0.2 x 0.3
expected double recombinant frequency = 0.06 = EDRF
Now that we know the value of the CC and the expected DRF, we can get the observed double recombinant frequency.
CC = observed double recombinant frequency/expected double recombinant frequency
- CC = 0.6
- EDRF = 0.06
CC x expected double recombinant frequency = observed double recombinant frequency
0.6 x 0.06 = observed double recombinant frequency
0.036 = observed double recombinant frequency = ODRF
Finally, as this is a frequency, we need to multiply it by the total number of individuals in the F2 to get the number of observed double recombinant individuals.
- ODRF = 0.036
- N = 1000
Double recombinant individuals = 0.036 x 1000 = 36 individuals xxyyzz.

From this diagram of fossils (sorry it’s a bit blurry) which layer is the youngest and which layer is the oldest? How do you know?
Answer:
The bottom layer is the oldest, and the top layer is the youngest
Explanation:
As time goes on more and more sediment gets piled onto a certain place, meaning the oldest fossils will keep getting deeper and deeper

Explanation:
A pair of identical twins develop leukemias, where immature white blood cells proliferate uncontrollably. In each case, the cancer cells analyzed from identical twins displayed an identical chromosomal mutation and this critical mutation was not found in the twins normal cells. The twins developed leukemia at different times in their lives. What is the best explanation for the origin of this chromosomal mutation
Answer:
The chromosomal rearrangement resulted from a rare somatic mutational event that occurred in utero
Explanation:
Leukemia is a progressive type of cancer where immature white blood cells (leukocytes) proliferate uncontrollably. Next-generation sequencing (NGS) technologies have shown that somatic mutations are relatively common in different types of leukemia such as, for example, acute myeloid leukemia (AML). Moreover, identical twins are developed from one fertilized egg (ovum) that splits and develops into two identical individuals that share all of their genes (i.e., they have exactly the same genetic information). In this case, it is expected that leukemogenesis was initiated in the utero by the occurrence of a chromosomal rearrangement and proceeded early during development as distinct clonalities. In addition, the fact that identical twins developed leukemia at different times in their lives also indicates that this malignancy wasn't caused by only one mutation, but instead it was triggered by multiple mutational events (i.e., leukemia is a multistep cancer caused by secondary genetic changes).

The “great dying,” which saw 96% of all species extinct, was partially caused by(1 point)
an asteroid impact.
lower levels of carbon dioxide in the air.
bacteria producing large amounts of toxic methane.
algae consuming too much oxygen from the ocean.
The “great dying,” which saw 96% of all species extinct, was partially caused by an asteroid impact. So, the correct option is A.
What do you mean by Species?Species may be defined as a group of organisms that can reproduce with one another in nature and produce fertile offspring.
An asteroid impact threatens the whole biodiversity to a large extent. It leads to the destruction of almost all life forms living on the earth's surface.
Therefore, the “great dying,” which saw 96% of all species extinct, was partially caused by an asteroid impact.

Answer:
mass
Explanation:
An Air mass is a volume of air defined by its temperature and water vapor content. A front is the border between two air masses.
In meteorology, mass is a volume of air defined by its temperature and water vapor content.
What is meteorology?In the academic, public, and private sectors (government and business), meteorologists work in these fields. Some of the businesses and organizations who employ meteorologists or make use of various meteorological services.
Although we will touch on a few other topics as well, the main focus of this course will be on weather analysis and forecasting. After all, everyone is affected by the weather every single day in some way.
Meteorology is defined as "the science of the atmosphere covering both weather and climate" in the Met Office's Meteorological Glossary.
