Answer and Explanation:
<u>Cross:</u> aa Bb dd Ee x AA bb Dd Ee
We can calculate the probability of getting heterozygous individuals in the progeny by using the <u>product rule</u>. Assuming that these four genes <u>assort independently</u> (<em>events that occur independently from each other</em>), we can infer that the F1 will have the next genotypic proportions for each gene:
1) aa x AA
F1) 4/4=1 Aa
2) Bb x bb
F1) ½ bb
½ Bb
3) dd x Dd
F1) ½ dd
½ Dd
4) Ee x Ee
F1) ¼ EE
2/4 = ½ Ee
¼ ee
So, to know what the probability is that the F1 of being heterozygous for all loci, we must multiply the respective individual probabilities of getting a heterozygous genotype, like this:
1 Aa x ½ Bb x ½ Dd x ½ Ee = 1/8 AaBbDdEe
Answer:
What is a good example of a response-based definition of stress?
Bruce experiences stress because his heart rate increased when he noticed Jack had a knife.
Explanation:
Stress can have many different causes. In this case, it is produced by seeing danger in Jack by having a knife. His heart rate increases because this is a common response in stress, which would enable people to scape. It is important to control stress lebels.
A stressor is distinguished as a threat. If someone anticipates that it could lead to some kind of harm, loss, or other negative consequence. However, if you see the positive side and believe that it carries the potential for gain or personal growth, it would be appraised as a Challenge.
Answer:
cancellation
Explanation:
A factor in the numerator is <em>cancelled by dividing it</em> by the same factor in the denominator. The quotient is 1, the multiplicative identity element.
Because it ensures that all organisms produced via sexual reproduction contain the correct number of chromosomes. Meiosis<span> also produces genetic variation by way of the process of recombination.</span>
Answer:Self-assembly into a simple membrane
Explanation:
The cell membrane is the biological membrane that separates the interior of the cell to the exterior of the cell.
The cell membrane is made of lipid by-layer. The first cell membrane was made of lipids. It is so because it has the ability to assemble and form a membrane like structure.
It helps in entry and exit of the substances from inside of the cell to outside and vice versa.
