Which statement correctly describes the sequence of bases found in this type of molecule?
In DNA, the sequence of bases consists of adenine (A), thymine (T), guanine (G), and cytosine (C) that form complementary base pairs (A with T, and G with C). The sequence of these bases encodes genetic information that determines the characteristics of an organism.
What statement best describes the genetic information associated with the two of a chromosome?
Each pair of chromosomes contains one chromosome from the mother and one from the father. These two chromosomes carry genetic information that determines an individual's traits and characteristics. The combination of genetic information from both parents contributes to the unique genetic makeup of an individual.
What statement best describes the main function of a nucleic acid?
Nucleic acids, such as DNA and RNA, carry genetic information that directs cellular functions and processes within living organisms. They serve as the blueprint for the synthesis of proteins and are essential for the storage, transmission, and expression of genetic information.
What statement best describes the technique known as amniocentesis?
Amniocentesis is a procedure where a small amount of amniotic fluid is extracted from the amniotic sac surrounding the fetus. This fluid contains fetal cells that can be used for genetic testing to detect chromosomal abnormalities or genetic disorders. Amniocentesis is typically performed in the second trimester of pregnancy.
What is the difference between the gametes produced without corssing over and the ones produced with crossing over?
Gametes produced without crossing over are genetically identical to the parent cell, whereas gametes produced with crossing over have a mix of genetic material from both parents due to exchange of genetic material between homologous chromosomes. Crossing over increases genetic diversity in offspring.

What correctly describes the similarities between fraternal twins?
They are as similar as any other two siblings.
Which statement is FALSE concerning gametes produced by meiosis?
The statement that is FALSE concerning gametes produced by meiosis is that they are genetically identical to the parent cell. Meiosis results in the formation of haploid gametes with genetic variation due to crossing over and independent assortment of chromosomes during the process.
What term describes genetic composition?
DNA?
What statement best describes the main function of a nucleic acid?
Nucleic acids, such as DNA and RNA, carry genetic information that directs cellular functions and processes within living organisms. They serve as the blueprint for the synthesis of proteins and are essential for the storage, transmission, and expression of genetic information.
Which describes an advantage of sexual reproduction?
Genetic variation
What can geneticist use the principles of probability for?
To predict the traits of the offspring produced by genetic crosses.
Who produced the first genetic map?
sturtevant
What is a true statement of the genetic material in viruses?
it can be DNA or RNA
What term describes the biological and genetic foundation of an individual?
DNA
Do plants decrease genetic variability when spores are produced?
No
