Dizygotic twins develops from two separate fertilized eggs and share 50 percent of their genes.

Further Explanation:

Genotypes help in the genetic makeup of any individual.Phenotype describes as a physical characteristic of an individual. Genotype responsible for the phenotypes of any individual.

Twins are of two types:

Monozygotic
Dizygotic

In monozygotic twins only one egg and sperm fertilized and form identical twins.In this fertilized egg divide into two parts and they have same genetic makup .They share 100% similar gene.

In dizygotic twins two eggs released in one cycle and fertilized with two sperm.They form dizygotic or fraternal twins. They share 50% of smiliarities between gene and they are like sibling born at different time.

Factor that increase increase the probability of twins are :

Mothers having age around 30-40
People belong to Africa and America
IVF technique
Overweight
Heridity

DNA has two strands. If the sequence of nucleotides of one strand was known, is it possible to use that information to determine

yanalaym [24]

It is possible to use the information of the nucleotide sequence of one strand to determine the sequence of the other strand.

Deoxyribonucleic acid (DNA) is a biological molecule with two strands. Each strand is made up of a sequence of nucleotides. The DNA nucleotides are Adenine (A), Cytosine (C), Guanine (G) and Thymine (T).

In a DNA molecule, Adenine forms an hydrogen bond with Thymine i.e. A-T, while Guanine forms an hydrogen bond with Cytosine i.e. G-C.

Therefore, it is possible to use the information of the nucleotide sequence of one strand to determine the sequence of the other strand. For example, a strand with ATGCGTACGAT will form the following sequence: TACGCATGCTA

Which of the following statements is true?

mafiozo [28]

Answer:

The correct answer is: D) The kidneys are paired organs that regulate water and electrolyte balance in terrestrial vertebrates.

Explanation:

The kidneys are the organs that control, for example, the volume of body fluid compartments, acid-base balance, and electrolyte concentrations. These organs are also key to eliminate the toxins from the body.

The kidneys are always two (when not is because of a pathology or the surgical removal of one of the two) and are present in vertebrates.

The kidneys do not regulate blood glucose. That is the job of the pancreas through two hormones called insulin and glucagon.

The kidneys do not remove nitrogenous wastes (urea) from the urine, instead they filtrate these wastes from the blood for these to be excreted through urine.
