What is the Difference Between Maternal and Paternal Chromosomes

The main difference between maternal and paternal chromosomes is that a sex chromosome with maternal origin can only be an X chromosome while a sex chromosome with paternal origin can be either an X chromosome or Y chromosome. Therefore, maternal chromosomes are called homogametic chromosomes while paternal chromosomes are called heterogametic chromosomes .
Maternal and parental chromosomes are the two types of chromosomes found in the nucleus of the zygote produced after the coalition of gametes. Each set of chromosomes with different origins consists of 23 chromosomes ( in humans ), making up a core with 46 chromosomes in it .

What are Maternal Chromosomes

maternal chromosomes are the chromosomes in the lens nucleus with a enate origin. This means these chromosomes come through the female gamete during fertilization. In humans, the set of the maternal chromosomes contain 22 autosomal chromosomes and a one arouse chromosome. here, the sex chromosome is always an ten chromosome. It is due to the presence of two X chromosomes in females, determining their sex .

What are Paternal Chromosomes

agnate chromosomes are the chromosomes in the nucleus with parental origin. It means ; these chromosomes come through the male gamete during fertilization. Same as the parental chromosomes, the set of paternal chromosomes in humans contains 22 autosomal chromosomes. here, each parental chromosome has a homologous chromosome in the enate chromosome plant .
Difference Between Maternal and Paternal Chromosomes_Figure 2 In accession to autosomal chromosomes, both types of sexual activity chromosomes, the X chromosome or the Y chromosome, can occur as the arouse chromosomes in the agnate chromosome arrange. consequently, the type of sex chromosome in the paternal chromosome set determines the arouse of the new individual .

Similarities Between Maternal and Paternal Chromosomes

  • Maternal and paternal chromosomes are the two types of chromosomes inside the nucleus.
  • Each type of chromosome set contains 23 chromosomes.
  • Also, each chromosome set is made up of 22 autosomal chromosomes and one sex chromosome.
  • A particular autosomal chromosome with maternal origin is homologous with another autosomal chromosome with paternal origin. Sex chromosomes can be homologous in the XX situation and heterozygous in XY situation.
  • Furthermore, both chromosome sets can contain X chromosomes.

Difference Between Maternal and Paternal Chromosomes

Definition

enate chromosomes refer to the determined of chromosomes that comes from the female gametes while parental chromosomes refer to the located of chromosomes that comes from the male gametes. frankincense, this is the basic remainder between parental and agnate chromosomes .

Origin

Maternal chromosomes originate from the mother while the paternal chromosomes originate from the church father .

Type of Sex Chromosomes

type of sex chromosomes they possess is a main difference between parental and parental chromosomes. Maternal sex chromosome is constantly an ten chromosome while agnate sex chromosome can be either an x or Y chromosome .

Homogametic/Heterogametic

Another remainder between enate and paternal chromosomes is that parental chromosomes are homogametic while agnate chromosomes are heterogametic .

Conclusion

maternal chromosomes are the set of chromosomes in the nucleus with a maternal origin. For exemplify, paternal chromosomes are the moment set of chromosomes in the core with the paternal origin. parental chromosomes are homogametic chromosomes since each female gamete contains X chromosomes as the sexual activity chromosomes. On the other hand, male gametes either contain adam or Y chromosome as the sex chromosome. consequently, the main remainder between parental and paternal chromosomes is the type of sex chromosomes introduce in the chromosome determined.
