Why can't we inherit both copies of a homologous chromosome from the same parent?

If we inherited both copies of a homologous chromosome, that would mean that we would only have one parent. Since mammals reproduce by sexual reproduction, it is impossible for this to happen.

In humans an individual inherits one copy of each homologous chromosome from each parent In turn one of each homologous pair goes to a gamete to be passed on Females inherit two X chromosomes and male?
AnswerBoys must inherit the Y chromosome from their father.
What is Unparental Disomy?
Occurs when a person receives two copies of a chromosome, or of part of a chromosome, from one parent and no copies from the other parent.
Are tetrad and homologous chromosomes the same?
Homologous chromosome is when a pair of chromosomes containing the same linear gene sequences, each derived from one parent, and a tetrad is formed when 2 homologous chromosomes join together
What would happen if the septum did not form during binary fission?
The parent cell would now have two copies of the chromosome
What contains genes?
If chromosomes are homologous, that means that each the the four chomosomes that came from the male parent has a corresponding chromosome from the female parent.Prentence Hall Biology

What are The two sets of chromosome that come from the female parent and the male parent?
heterozygous
What are pair of similar chromosomes called?
HomologousWe receive one complete set of chromosomes from each parent. This means that for each chromosome, say chromosome 7, there are two copies in every cell of our bodies: the maternal and paternal copies of chromosome 7.The two copies of one chromosome are called a pair of homologous chromosomes.
What is Unparental Disomy?
Occurs when a person receives two copies of a chromosome, or of part of a chromosome, from one parent and no copies from the other parent.
Where do homologous chromosome come from?
I believe one is inherited from each parent.
When fertilization occurs offspring inherit?
One homologous chromosomes in a pair from each parent
What type of DNA do daughters inherit from both parents but sons only inherit from mothers?
Daughters inherit an X-chromosome from each parent but sons receive an X-chromosome only from the mother. The father supplies a Y-chromosome to make the child a boy.
Describe Mendel’s law of segregation and state how it connects to meiosis?
Mendels law of segregation states that an organism inherits two copies of each gene, one from each parent. An organism can donate only one copy pf each gene in their gametes. the two copies of each gene segregate, or separate, during gamete formation. The law connects to meiosis because homologous chromosomes seperate into different daughter cells and inherit only a chromosome from the parent cell, this connects to his law as an organism only inherits one trait from their parent.
Are tetrad and homologous chromosomes the same?
Homologous chromosome is when a pair of chromosomes containing the same linear gene sequences, each derived from one parent, and a tetrad is formed when 2 homologous chromosomes join together
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
What type of DNA do daughters and sons inherit at the rate of one each from each parent?
Every child receives an X-chromosome from each parent.
Describe and distinguish between replicated chromosomes and homologous chromosomes?
Chromosomes usually occur in pairs in body cells. One chromosome in the pair comes from one parent and the other chromosome comes from the other parent. The two chromosomes are the same size and shape and carry the same genes in the same positions. They are called homologous chromosomes. When cells divide the chromosomes first have to copy themselves (ie replicate). Each homologous chromosome makes a replica of itself, and the original and replica are attached to each other at a region called the centromere.
