Human traits are usually?
Learned
How are crossing over and recombination related?
Genetic recombination occurs during meiosis cell division. As genes cross over during this process, scientists track the genes to study their linkage.
How do number of chromosome affects the genes and DNA?
Not at a fundamental level, chromosomes are just the way that genes are clumped together. But on a practical level, chromosomes are what the cells manipulate during growth and (especially) during reproduction.
Can a single protein have multiple genes?
Yes. A protein produced by multiple genes are cased by fusion genes. Usually a protein is translated from a mRNA which is transcribed from a DNA. After transcription, RNA is rearranged by so-called RNA splicing in which some of short sequences are selected(Exon) or deleted(Intron). During the splicing two different genes can join together and it is called trans-splicing. After trans-splicing, mRNA is translated into a protein, so the protein has two genes. Most cases these fusion genes are oncogenes which cause Cancerous diseases.
When crossing-over occurs what genes stay together?
linked genes

What is new gene combinations?
when genes cross over during meiosis, then split they from genes that differ.
Are polygenic genes dominant genes?
Polygenic genes are usually dominant genes.

What is the number of genes that usually determines a trait?
the number of genes that usually determine a trait
When crossing-over occurs what genes stay together?
linked genes
Suppose that the distance between two genes on a linkage map is 7 units The cross over freguency between the two genes is?
If the distance between two genes on a linkage map is 7 units, the cross over frequency between the two genes is still 7 units.
What happens when you cross a dog with a cat?
It is impossible to cross a cat with a dog. The genes and chromosomes are incompatible.
The sorting and recombining of genes during meiosis and fertilization usually leads to the production of?
4 genetically different daughter cells
Why are most of your traits are not inherited according to the for a simple mono hybrid cross in which we look at character that is coded for by only one dominant allele and one recessive allele?
there are many other types of inheritance types such a polygenic, pleitrophy, codominance, etc. Also, some genes are linked (close together on the same chromosome) so that they stay usually together during crossing over ex: red hair and freckles, blonde hair and blue eyes
