Pedigrees and karyotypes provide the means for individuals to identify their risks of genetic disorders. What can be evident on a karyotype but not seen on a pedigree? A. family carriers of a genetic disorder B. family history of a genetic disorder C. risk of a genetic disorder in offspring D. a visual image of a chromosomal defect.

Answers

Answer 1

Answer: I think the correct answer from the choices listed above is option D. The thing that can be evident on a karyotype but not seed on a pedigree would be that the presence of a visual image of a chromosomal defect. Hope this answers the question. Have a nice day.

Answer 2

Answer:

The correct answer would be D. a visual image of a chromosomal defect.

Karyotype is defined as a visual display of the number and appearance of all the chromosome present in the cell.

It is used to detect any chromosomal abnormality such as a change in chromosome number, change in chromosome set, malformed chromosome et cetera.

In contrast, a pedigree chart is a diagrammatic representation of phenotype or appearance of a particular gene in a number of generations.

it shows the family history of the genetic disorder, risk of that disorder in an offspring, et cetera.

Answers

Trisomy is the answer.A trisomy is a chromosome abnormality in which a person has three copies of a particular chromosome rather than the expected two.Trisomies can have varying effects on a person's health depending on which chromosome is affected by the trisomy. Some trisomies such as trisomy x have only mild effects whereas others such as trisomy 21 also known as Down syndrome result in health problems and development delays.Many Trisomies can have fatal consequences such as trisomy 16 or trisomy 18 .They frequently cause miscarriages or loss of the baby shortly after birth.

The correct answer is option b. "Bilateral symmetry and no cephalization".

Explanation:

"Platyhelminthes" are a type of flatworms that lack circulatory and respiratory organs, and have an unique digestive cavity. Two characteristics that define platyhelminthes are they have bilateral symmetry and no cephalization. Bilateral symmetry means that if you draw a line from the head to the tail of the flatworm, you will obtain two mirror sides. Regarding cephalization, platyhelminthes are considered not fully cephalized as they only have the beginnings of cephalization.

Answer;

-DNA molecule

Explanation;

-According to cell theory; All known living things are made up of one or more cells. All living cells arise from pre-existing cells by division. The cell is the fundamental unit of structure and function in all living organisms.

-The modern version of the Cell Theory includes the ideas that:

Energy flow occurs within cells.
Heredity information (DNA) is passed on from cell to cell.
All cells have the same basic chemical composition.

-Therefore the study of DNA molecule was instrumental in the formulation of the modern cell theory.
