No, actually many traits such as intelligence, height and skin color are polygeneic, meaning they are determined by more than one genes, so they don't come from one gene from both parents. And further going against the statement, TDF (Testis determining factor) is found only on the holandric part (non-homologous) of the Y chromosome, so that gene is only coming from one parent (the father).

What is one difference between single gene trait and a polygenic trait?
Polygenic traits result in more variation because so many more alleles are involved in the process of reproduction.
What is an XO genotype?
it means it has one gene from the dominant trait and one gene from the recessive trait
What is the gene that codes for a particular trait is known as what?
An allele is a gene for a specific trait. Cells contain two alleles for every gene, with one allele provided by each parent of an organism.
What does it mean that an organism is homozygous recessive for a trait?
That organism has two recessive alleles for that trait, one from each parent. It will display the recessive trait.
What is a genetic cross with one trait?
Crosses involving one gene or trait are called monohybrid crosses.
What is a trait that is determined by a gene found on one of the sex chromosomes?
A sex linked trait.
What is a physical trait determined by what type of gene?
The nucleus divedes
What is one difference between single gene trait and a polygenic trait?
Polygenic traits result in more variation because so many more alleles are involved in the process of reproduction.
Can a single gene control a single trait.?
It was once believed that one gene controls one trait, so it is possible. Currently, the belief is that one gene can interact with other genes to control a trait, and that one gene can control more than one trait.
What is an XO genotype?
it means it has one gene from the dominant trait and one gene from the recessive trait
What is a trait that is expressed even if only one gene for that form of the trait is inherited?
It is a dominant trait. You only need one gene of a dominant trait for that trait to be expressed. You need two copies of the recessive trait in order for the trait to be expressed.
Can a single gene control a single trait?
It was once believed that one gene controls one trait, so it is possible. Currently, the belief is that one gene can interact with other genes to control a trait, and that one gene can control more than one trait.
Is a non mendelian trait controlled by one gene?
A non Mendelian trait can be controlled by one gene. When a trait is controlled by one gene it results in genetic disorders. Examples of disorders due to single gene inheritance - Huntington disease, Fragile-X syndrome.
A plant that is hybrid for a trait is?
Has one dominant and one recessive gene for that particular trait.
How many genes does an offspring receive from each parent for a trait?
23 from each parent... that's a total of 46 genes from both parents :D
Principle that states that the inheritance of a gene for one trait does not affect the inheritance of the gene for another trait?
Principle of independent assortment
Will an offsping show a recessive trait if only one of its parents has the gene for that trait?
No
