Biology

LiRa [457]4 years ago

Answer:

The correct answer would be option c. Y chromosome.

In humans, the males contain one X chromosome and one Y chromosome. In contrast, females contain two X chromosomes.

Thus, DNA sampling of the Y chromosome would be best to determine if the two male samples are related or not.

In addition, mtDNA is often inherited from the mother and thus, it would not be a good option to determine the relationship between the male samples.

Round seeds are dominant over wrinkled seeds in
antoniya [11.8K]

Genotype - RR - 25%, Rr - 50%, rr - 25% (1:2:1)

Phenotype - Round seeds - 75%, Wrinkled seeds - 25% (3:1)

<h3>How explain your answer?</h3>

Let the letter "r" stand for the alleles, where R is round seeds and r is wrinkled seeds. A genotype is an individual's genes represented through alleles. Phenotypes are how the genes express themselves. In other words, genotypes will be written using letters, the alleles, and phenotypes will be the possible outcomes of the alleles.

Both of the parent seeds have the genotypes Rr and the phenotype of round seeds.

If you create punnet square (which had four boxes in total) 1 will have RR, 2 will have Rr, and 1 will have rr. These are the ratios for the genotypes. Each box represents 25%, so the percentages will be 25, 50, and 25. Finally, 3 of these boxes (RR and Rr) will result in round seeds because those are dominant. Only the genotype rr will result in wrinkled phenotype. Therefore, the ratio is 3:1 or 75% to 25%.

Thus, this could be the answer.

lana66690 [7]

Answer:

The correct answer is - by absorbing too much sodium and water into the cells in the respiratory system.

Explanation:

Cystic fibrosis or CF is a genetic disorder that is caused by the presence of two defective genes that leads to the production of thick and sticky mucus in an individual that affects the respiratory and digestive system by clogging mucus in it.

Due to defective genes, there is an abnormal electrolyte transport system develops in which cells of the respiratory system including the lungs absorb an excessive amount of salt (sodium) and water. It all caused by deletion of the three letters which means an amino acid from a gene that leads to the disruption of the protein that controls the production of the mucus and abnormal electrolyte transport.
