there are both paternal and maternal chromosomes, which carry maternal/paternal genes.
In cases where a defective gene is located on the X chromosome, a female can inherit the gene from either parent. If the mother carries one defective X chromosome, she can pass it on to her daughter. Similarly, if the father has the defective gene on his single X chromosome, he will pass it to all his daughters, as they inherit his X chromosome. Therefore, females can receive the defective gene from both maternal and paternal sources.
Two alleles represent a gene. ETC- The paternal (fathers) allele is B (for brown eyes) The mothers (maternal) is b ( for blue eyes) The capital B is the dominant allele, lowercase b is recessive. Therefore, a punnet square will show the offspring can be either hetrozygous or homozygous (recessive or dominant) Alleles represent the charactersitic, while a gene is a segment of DNA where heredity is based.
Another name for maternal twins is identical twins. Maternal twins come from a single fertilized egg that splits into two, resulting in two babies with the same genetic makeup.
The gene that expresses itself over the other is Dominant. The former gene is recessive.
Gene flow
Maternal imprinting and paternal imprinting are two types of epigenetic phenomena that affect gene expression based on the parent of origin. Maternal imprinting occurs when a gene is only expressed if it is inherited from the mother, while paternal imprinting occurs when a gene is only expressed if it is inherited from the father. This means that certain genes are silenced or activated based on whether they come from the mother or the father. These differences in imprinting can have significant effects on development and disease susceptibility.
A gene that shows maternal effect inheritance is one where the phenotype of the offspring is determined by the genotype of the mother, rather than the offspring's own genotype. This means that even if the offspring carries a certain genetic variant, it will only display the phenotype associated with the mother's genotype.
This is called bicoid mutant phenotype, and is caused by a maternal effect gene which is a gene that, when mutant in the mother, results in a mutant phenotype of the offspring regardless of the offspring's genotype.

This most commonly occurs if the disorder is recessive, meaning you must carry two copies of the gene which causes the disorder in order to show it.Everyone has two copies of each gene, one paternal and one maternal. If you only carry one copy (allele) of the gene which causes the recessive disorder and your other copy of that gene is normal, you will not have the disorder. However, you can carry it on if you have a child with someone else who also carries the gene which causes the disorder and the child gets two copies of the disorder gene.
In cases where a defective gene is located on the X chromosome, a female can inherit the gene from either parent. If the mother carries one defective X chromosome, she can pass it on to her daughter. Similarly, if the father has the defective gene on his single X chromosome, he will pass it to all his daughters, as they inherit his X chromosome.
