A geneticist is mapping the chromosomes of the newly captured gremlin. Stripe is heterozygous for three linked genes with alleles Ee, Hh, and Bb, that determine if gremlins are evil (E), have hair (H), and biting teeth (B). In order to determine if the three genes are linked, a standard testcross was done, and the 1000 offspring had the following genotypes: 48 ee Hh bb 36 ee hh Bb 400 ee Hh Bb 4 Ee Hh Bb 426 Ee hh bb 46 Ee hh Bb 38 Ee Hh bb 2 ee hh bb What is the recombination frequency between genes E and H
Recombination frequency determines if two genes are linked or if they segregate independently from each other. The recombination frequency between E and H is 8%
What are linked genes?Linked genes are those that are too close to each other in the same chromosome and they do not segregate independently.
These are the linked genes that do not exhibit an independent distribution, and they are inherited together more frequently.
What is recombination frequency?Recombination frequency can be defined as the crossing over events frequency occurring between two genes.
The value of recombination frequency indicates weather genes are linked or not. The maximum recombination frequency is always 50%.
When RF is 50% or more, we can assume that genes are not linked.
In the exposed example, we can recognize the parental gametes in the descendants because their phenotypes are the most frequent, while the double recombinants are the less frequent.
Parental)
400 ee Hh Bb
426 Ee hh bb
Double recombinant)
4 Ee Hh Bb
2 ee hh bb
Simple recombinant)
48 ee Hh bb
36 ee hh Bb
46 Ee hh Bb
38 Ee Hh bb
We will call Region I to the area between genes E and H and Region II to the area between genes H and B.
------------E------------H--------------B-----------
/---RI------//------RII-----/
To calculate the recombination frequency between E and H we just need to consider region I. We will call P1 to the recombination frequency in this region.
P1 = (R + DR) / N
Where:
R is the number of simple recombinants in this region, DR is the number of double recombinants in each region, and N is the total number of individuals.Now, let us analyze the information.
We know that individuals carrying double recombinant gametes are
Ee Hh Bbee hh bbWe know that the recessive parent from the testcross could only provide the following gametes ⇒ ehb
This leads us to assume that the followings are the double recombinant gametes from the trihybrid parent,
EHBehbSince these gametes are the product of a double recombination event in region I and II, we can assume that the parental gametes of the trihybrid individual are
eHbEhBHence the simple recombinant gametes in region I are
EHbehBNow, according to this analysis, we know that
Simple recombinants in region I
36 ee hh Bb
38 Ee Hh bb
Double recombinants
4 Ee Hh Bb
2 ee hh bb
Total number of individuals
N = 1000
Recombination frequency in Region I
P1 = (R + DR) / N
P1 = (38 + 36 + 4 + 2) / 1000
P1 = 80 / 1000
P1 = 0.08 = 8%
The recombination frequency between genes E and H is P1 = 8%

Need answer please asap
Rachel drove 300 miles from her home to Philadelphia to visit her sister and then returned home a week later. At the end of the trip what was her displacement and distance traveled in that order
Answer:
The correct answer would be - zero miles, 600 miles.
Explanation:
She started from the same point and after the trip, she ended it on the same point in Philadelphia therefore the displacement is expected to be zero.
The distance she traveled would be 2 into 300 miles as she traveled to her sister and traveled back from there so
Distance = 2*300
= 600 miles.
Thus, the correct answer would be - 0 and 600 miles.
The energy that fuels food webs begins as light energy from the sun. True or False
Answer: i think its true. ( based of information i got)
Explanation: The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers such as plants, algae, and cyanobacteria use the energy from sunlight to make organic matter from carbon dioxide and water. This establishes the beginning of energy flow through almost all food webs. also A food web consists of many food chains. A food chain only follows just one path as animals find food. eg: A hawk eats a snake, which has eaten a frog, which has eaten a grasshopper, which has eaten grass. A food web shows the many different paths plants and animals are connected.

As with Part H. you have a total body concentration of 300 mOsM and body volume of 3 liters. You now add 2 liters of a 500 mOsM solution. The solution is equal parts NaCI (nonpenetrating) and urea (penetrating), so it has 250 mosmol/L NaCI and 250 mosmol/L urea. Answer the following questions about your new solution:
Drag the terms on the left to the appropriate blanks on the right to complete the sentences.
The solution is_______ osmotic to the body.
What is the concentration of nonpenetrating solutes (NP) in the solution?
What is the internal concentration of the body's cells? (All intracellular solutes are nonpenetrating.)

Answer:
- The solution is hyperosmotic to the body.
- What is the concentration of nonpenetrating solutes (NP) in the solution? 500 mosmol/L
- What is the internal concentration of the body's cells? (All intracellular solutes are nonpenetrating.) 300 mosmol/L
- When the cells reach equilibrium after addition of the solution to the body, has cell volume increased, decreased, or stayed the same? increased
- Based on your answer regarding water movement, the solution was hypotonic to the body's cells.
Explanation:
A hyperosmotic (or hypertonic) solution is a solution with a greater solute concentration. If a cell is placed in a hyperosmotic solution the water will leave the cell and the cell will shrink. Conversely, a hypotonic solution is a solution that has a lower concentration of solute. If a cell is placed in a hypotonic solution the water will enter the cell through osmosis and the cell increases in size. In this case, the NaCl is a non-penetrating solute, and thereby the concentration in the body's cells maintains constant. Moreover, urea is a penetrating solute, thereby it will penetrate in the cells until the equilibrium is reached (i.e., the cells will increase in volume).
A woman with a straight hairline has as child with a man who is heterozygous
and has a widow's peak.
What is the mother's genotype?
Answer:
aa
Explanation:
A widow's peak is the dominant genotype so one must not have that trait. If it was presented then the woman would have the genotype.
A widow's peak is dominant so the man would be either AA or Aa. Since it stated that his is heterozygous (Hetero meaning two different), his genotype would be Aa (again since a widow's peak is the dominant, it only needs one dominant genotype)

Explanation:
How can you use genetics to study human inheritance?
Answer:
by analyzing how genes influence the development of phenotypic traits, i.e., by determining the association between phenotypic traits and changes in DNA sequence
Explanation:
Genetics is a discipline that studies how genetic variation, i.e., the variation in the Deoxiriibunicleinc acid (DNA) molecule, is associated with the transmission of heredity, and how the environment influences this process. The DNA is a molecule that carries the instructions to perform all metabolic functions (eg., reproduction, development, growth, etc). Thus, advancements in genetics enabled us to decipher how phenotypic traits pass from parents/ancestors to their offspring/descendence. Genes are segments of DNA that carry the information (genetic information) to determine each phenotypic trait. During reproduction, genes are passed from one generation to the next, thereby transmitting this information across generations.
