What is maternal chromosome and paternal chromosome?
What is maternal chromosome and paternal chromosome?
One of these chromosomes is derived from the male parent (parental chromosome) and one from the female (maternal chromosome). The chromosomes in this pair are called homologs – there is one paternal and one maternal homolog.
What is maternal and paternal chromosomes in meiosis?
Meiosis is a form of cell division that produces gametes, or egg and sperm cells. During the first phase of meiosis, the homologous pairs of maternal and paternal chromosomes align. Crossovers result in recombination and the exchange of genetic material between the maternal and paternal chromosomes.
How are maternal and paternal chromosomes passed on in meiosis?
In MEIOSIS I, each daughter cell gets EITHER the maternal OR the paternal PAIR of chromosomes. [NOTE: each chromosome is separate. There will almost always be a mix of chromosomes from the mother and father in the entire cell. In MITOSIS, each daughter cell gets ONE maternal chromosome and ONE paternal chromosome.
How many maternal chromosomes are there?

What is a maternal chromosome?
Maternal chromosomes are the chromosomes in the nucleus with a maternal 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 single sex chromosome.
What is a maternal homolog?
A couple of homologous chromosomes, or homologs, are a set of one maternal and one paternal chromosome that pair up with each other inside a cell during fertilization.
