Having two copies of the mutated genes cause sickle cell anemia, but having just one copy does not, and can actually protect against malaria - an example of how mutations are sometimes beneficial.
The majority of mutations have neither negative nor positive effects on the organism in which they occur. These mutations are called neutral mutations. Examples include silent point mutations. They are neutral because they do not change the amino acids in the proteins they encode.
Hope this helped :)
Answer:
If the question is referring to Mendel's postulates, all options are correct
Explanation:
Gregor Mendel discovered that certain components he called UNIT FACTORS determine inheritance. This unit factors were later described to be genes in modern genetics. He discovered that an organism receives two forms of this unit factors from each parent, which he called ALLELES. In his experiments, he observed that one of the pair of alleles have the ability to mask the expression of its variant pair. He called the allele that masks, DOMINANT allele while the allele that is masked, RECESSIVE allele.
During his cross experiment, he discovered that the alleles of a gene (unit factor) separates into gametes, he called this LAW OF SEGREGATION. He notably discovered in his cross involving two different characters that the segregation of the alleles of one gene into gametes does not influence the segregation of the alleles of the other gene. He termed this his LAW OF INDEPENDENT ASSORTMENT.
Answer:
According to the image, the approximate QT interval is 0.4 seconds.
Explanation:
The QT interval is the space between the beginning of the QRS complex and the end of the T wave, which represents from the beginning of depolarization to ventricular repolarization.
Considering that the extandardized measurements of an EKG, where the paper circulates at a speed of 25 mm/s, 1 mm horizontal —measuring time— has an equivalence of 0.04 s.
In the image, there is 10 mm between the beginning of the QRS and the end of the T wave, so:
0.04 seconds X 10 mm = 0.4 seconds.
Then, the estimated QT interval is 0.4 seconds.
Answer:
The brothers have different alleles.
