Answer:
Complementation.
Explanation:
Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.
A trait refers to the specific features or characteristics possessed by a living organism. It is essentially transferred from the parent of a living organism to her offspring and as such distinguishes him or her. Some examples of traits in genetics are colorblindness, handedness, curly hair, height, complexion, weight, hair color, dimples, tongue-roll, etc.
Artificial selection is also known as selective breeding and it is a process that involves humans (breeders) selecting the animal or plant with desirable traits in order to reproduce favorable offspring having phenotypic traits.
Complementation can be defined as a relationship between two strains of a living organism both having distinct homo-zygous recessive mutations and results in the expression of a wild-type phenotype when crossed or mated.
In this scenario, there are two different varieties of a snapdragon flower having golden leaves rather than green leaves. Thus, crossing two different varieties of golden snapdragons would produce offsprings that have green leaves.
Hence, the above breeding is an example of complementation.
Answer:
The DNA will still move towards the positive electrode
Explanation:
Gel electrophoresis is a technique which is used by the molecular biologist to separate the fragments of DNA. In the procedure, a DNA sample of a particular concentration of DNA sample composed of a particular length of DNA is loaded into the samples.
The gel is usually set up with the positive electrode at the bottom and negative at the top which by mistake when placed at the bottom and positive at the top.
The DNA will still move from the DNA wells towards the positive side as the DNA moves in the gel as the DNA posses negative charge due to phosphate groups they have and therefore move towards the positive electrode (opposite charge always).
Thus, the DNA will still move towards the positive electrode is correct.
Admitting that the "a" is a capital A for normal pigmentation and "d" is a capital D for dimpled chin, meaning that these are the dominant traits, the fraction expected to be albino with a non-dimpled chin is of 1/16.
When two heterozygous are crossed and two characteristics are being analysed, the offspring quantity that will possess the two recessive traits can be represented by 1/16. This is easily confirmed when a Punnett square is made. Considering that both parents were heterozygous, on both sides of the crossing in the Punnett square, you would have the following alleles' combination: AD, Ad, aD, and ad. The offspring that would be homozygous recessive (aadd) would correspond to only 1/16.
The lower limb bones are attached to the axial skeleton by a ring of bones called the pelvic girdle. The pelvic girdle consists of the right and left hip bones.
The bones of the head and trunk of the vertebrate form the axial skeleton.
Answer:
The skeletal system works as a support structure for your body. It gives the body its shape, allows movement, makes blood cells, provides protection for organs and stores minerals.
