The difference between paternal and maternal chromosomes is who they come from!
There will also be genetic differences, i.e. differences in base sequences along the chromosomes, but that is true of any two people apart from monozygotic ("identical") twins.
"Pater" = "father", so paternal chromosomes are inherited via the male gamete (sperm or pollen). "Mater" = "Mum".
In textbook diagrams the two sets of chromosomes are sometimes colored differently, but that is only for information. There is no way you can look at a diploid cell and say, "That chromosome came from the female parent". In a human cell, the only thing you can be sure of is that the Y chromosome must have come from Dad, because Mum has no Y chromosomes to be passed on.
In humans, and many other animals, the male is called the heterogametic sex, because males can produce gametes that produce sons as well as gametes that produce daughters. The female gametes cannot determine the sex of offspring. When Henry VIII became frustrated with wives who did not bear him a son, he was on the wrong track!
Birds, on the other hand, do things the opposite way: the male is the homogametic sex (the sex chromosomes are WW) and the heterogametic sex is the female (WZ).
Paternal chromosomes are inherited from the father, while maternal chromosomes are inherited from the mother. They carry different genetic material and combine during fertilization to form a unique individual with traits from both parents.

What is the difference between Chiasma and Chiasmata?
Chiasma refers to the physical site of crossover between homologous chromosomes during meiosis, facilitating genetic recombination. Chiasmata are the visible manifestations of chiasmata, appearing as X-shaped structures that hold homologous chromosomes together before they separate during meiosis.
What is the exchange of genes between homologous pairs of chromosomes?
The exchange of genes between homologous pairs of chromosomes is called genetic recombination. This process occurs during meiosis, where corresponding segments of DNA are exchanged between maternal and paternal chromosomes, increasing genetic variation in offspring.
When does crossing over occur for oogenesis?
Crossing over occurs during prophase I of meiosis I in oogenesis, which is when homologous chromosomes exchange genetic material. This process increases genetic diversity by shuffling genetic information between maternal and paternal chromosomes.
Crossing over occurs when?
Crossing over occurs during meiosis when homologous chromosomes exchange genetic material, leading to genetic variation in offspring. This process helps increase genetic diversity by shuffling genes between maternal and paternal chromosomes.
What two events in meiosis lead to gene shuffling?
Crossing over during prophase I and random assortment of homologous chromosomes during metaphase I are the two events in meiosis that lead to gene shuffling. Crossing over exchanges genetic material between homologous chromosomes, while random assortment results in a different combination of maternal and paternal chromosomes in each gamete.
What is difference between maternal and paternal?
"Maternal" is of or pertaining to the mother, "paternal" is of or pertaining to the father.
What's the difference between maternal and paternal?
Paternal is related to the father while maternal is related to the mother. Example: Your maternal parent is your mother and your paternal parent is your father.
A maternal homologue and a paternal homologue synapse to form?
a pair of homologous chromosomes during meiosis. This pairing is called synapsis and allows for genetic recombination to occur between the maternal and paternal chromosomes, contributing to genetic diversity in offspring.
During prophase of meiosis 1 chromosomes from the organisms father called paternal chromosomes pair up with homologous maternal chromosomes donated by the mother to form a bythis process is called?
The process you are referring to is called synapsis. During synapsis, homologous chromosomes pair up to form a structure called a bivalent or tetrad. This allows for the exchange of genetic material between the maternal and paternal chromosomes, a process known as crossing over.
What is the difference between Chiasma and Chiasmata?
Chiasma refers to the physical site of crossover between homologous chromosomes during meiosis, facilitating genetic recombination. Chiasmata are the visible manifestations of chiasmata, appearing as X-shaped structures that hold homologous chromosomes together before they separate during meiosis.
What is the different between a paternal and paternity?
Paternal is related to the father while maternal is related to the mother. Example: Your maternal parent is your mother and your paternal parent is your father.
What is the difference between paternal and maternal relatives?
Maternal relatives are those people who are related to you through your mother's family. They include your mother's grandparents, parents and siblings, and the sibling's children (your cousins). Paternal relatives are those people who are related to you through your father's family. They include your father's grandparents, parents and siblings, and the siblings children (your cousins).
How do you differentiate between grandmothers?
Maternal means from your mother's side and paternal means from your father's side...So, maternal grandma = your mother's motherpaternal grandma = your father's mother,maternal uncle = your mother's brother,paternal uncle=your father's uncle,
Does meiosis have variation?
Yes, meiosis results in genetic variation due to processes such as crossing over (exchange of genetic material between homologous chromosomes) and random assortment of chromosomes. These mechanisms contribute to the unique combinations of maternal and paternal genes in the resulting gametes.
What event in meiosis leads to genetic variation in organisms?
Genetic crossover occurs, which causes a sharing and transference of genetic information between maternal and paternal copies of chromosomes and further enhances the genetic variability of their offspring.
Why is there a distiction between maternal and paternal grandparents?
maternal grandparents are your mothers parents therfore you must distinguish them from your paternal grandparents which are your fathers parents or things would get all mixed up. you would be saying your moms dad is your dads dad and things would get to seem like incest.
What is the difference between a chromatid and a sister chromatid?
Homologous chromosomes is a pair made of a paternal and maternal chromosomes. But sister chromatid is either pairs of paternal or maternal chromosomes
