In extra chromosomal inheritance the following three examples are discussed

1.Maternal effects depending indirectly on nuclear gene and involving no known cytoplasmic hereditary units.

2. cytoplasmic inheritance involving dispensable and infective hereditary particles in cytoplasm which may or may not depend on nuclear genes

3. Cytoplasmic inheritance involving essential organelles like chloroplasts and mitichondria.

What was a nickname for arsenic?

"inheritance powder" Arsenic was one of the favorite murder devices of the middle ages often used by people in rich families. Arsenic poisoning was often undetected at the time because it had many similar symptoms to cholera which was quite common at the time. It got this nickname because people would often use it to kill of family members and gain an inheritance.


Mendel postulated that individuals have elements in pairs that determine a single phenotype What are the paired elements?

The paired elements are what Mendel called "factors," which we now know as genes. Genes come in pairs, with one inherited from each parent, and determine traits, such as eye color or flower shape, in an individual. This pairing and inheritance of genes is the basis of Mendel's laws of inheritance.


What role does the negative charge of DNA play in cellular processes and genetic inheritance?

The negative charge of DNA helps to stabilize the structure of the molecule and allows it to interact with other molecules in the cell. This charge also plays a role in the process of genetic inheritance by helping to regulate the binding of proteins and enzymes that are involved in DNA replication, transcription, and other cellular processes.


What is an example of karyotyping?

Karyotyping is a laboratory technique used to visualize an individual's chromosomes. An example of karyotyping is when a karyotype is created from a blood sample to determine if a person has a chromosomal abnormality, such as Down syndrome, by analyzing the size, number, and shape of their chromosomes.

What are the exceptions to the Chromosomal Theory of Inheritance?

Exceptions to the Chromosomal Theory of Inheritance include genes located on organelle genomes (like mitochondria and chloroplasts), which are inherited independently of nuclear chromosomes. Additionally, certain genetic elements like transposons can move between chromosomes and affect inheritance patterns. Lastly, epigenetic modifications can also influence gene expression and inheritance independently of chromosomal DNA sequences.


What is a chromosomal landmark whose inheritance can be tracked?

The sex chromosomes, X and Y, are chromosomal landmarks whose inheritance can be tracked. They determine an individual's sex and are passed down from parents to offspring. By studying the inheritance patterns of these sex chromosomes, researchers can track gene flow and genetic diversity within populations.

The chromosomal theory of inheritance states that genes are carried from parents to their offspring by gravity?

False they aren't carried by gravity


What is Chromosomal Theory?

The chromosomal theory of inheritance states that genes are located on chromosomes and that the behavior of chromosomes during meiosis and fertilization accounts for inheritance patterns. This theory was proposed by Walter Sutton and Theodor Boveri in the early 20th century and provided a unifying explanation for Mendel's laws of inheritance.


What is the mode of inheritance of turner's syndrome?

Turner syndrome is typically the result of a random event, rather than being inherited from a person's parents. It is caused by a complete or partial absence of one of the X chromosomes, leading to a variety of physical and developmental differences.


Why did scientists use drosophila for chromosomal studies?

Scientists used Drosophila (fruit flies) for chromosomal studies because they have a short life cycle, produce many offspring, and have easily visible chromosomes. This made them ideal for studying inheritance patterns and chromosomal changes.


Discuss mendels conclusions and relate them to the chromosomal theory of inheritance?

Mendel's conclusions, based on his pea plant experiments, included the principles of segregation and independent assortment. These principles describe how genes are passed down from parent to offspring. The chromosomal theory of inheritance later connected Mendel's principles to the physical basis of heredity by identifying chromosomes as the carriers of genetic information, thus explaining how genes are inherited and expressed through the process of meiosis and fertilization.
