What information on a pedigree can tell yo whether a gene is on autosome or on a sex chromosomes?
You can tell by the patterns and, to a lesser extent, ratios of trait inheritance. Both sex-linked and autosomal traits can be dominant or recessive and the patterns for each type are different.
Usually for autosomal inheritance there isn't a difference in the ratios between males and females affected with the trait while in sex-link inheritance there is.
If there are traits that seem to skip a generation then they usually are recessive.
Genes that are located on the Y chromosome are passed from father to son, never to daughter whereas genes on the X chromosome can go to both. It's important to know that since normal human males only have one X, X-linked traits will be dominant for them whereas for females the trait can manifest in one dose (haplosufficiency) or would have to be in two doses (both X's would have to have the gene).

What are similarities between autosome and sex chromosome?
Both autosomes and sex chromosomes are types of chromosomes that carry genetic information and are crucial for inheritance. They both consist of DNA and proteins, and they play a role in determining an organism's traits. Additionally, each individual inherits one set of chromosomes from each parent, regardless of whether they are autosomes or sex chromosomes. However, while autosomes are the same in both sexes, sex chromosomes determine the biological sex of an organism and differ between males and females.
What best describes the purpose of the chromosomes in the nucleus of a cell?
The purpose of chromosomes in the nucleus of a cell is to contain genetic information that tells the cell what to do, how to behave etc. Chromosomes also contain the information that determines what you look like; whether you have brown hair, blue eyes etc.
What can you conclude about the trit followed in the pedigree below?
Without the specific pedigree provided, I can't draw conclusions about the traits or inheritance patterns observed in it. Generally, pedigrees help trace the inheritance of traits through generations, indicating whether a trait is dominant, recessive, autosomal, or sex-linked. Analyzing the pattern of affected and unaffected individuals can reveal important information about the genetic basis of the trait in question. Please provide more details about the pedigree for a more accurate interpretation.
What are pedigree charts used for?
Pedigree is used to determine wheather a trait is inherited
What is the functions of sex chromosomes?
They Carry Genes That Determine Whether Make Or Female
What is the difference between an autosome and a sexchromosome?
An autosome is any of the 23 chromosomes which is not an X or Y chromosome. A sex chromosome is effectively the same as an autosome, apart from depending upon whether you inherit a Y chromosome or not, a sex chromosome will determine your gender. Hence the name.

What is the diffrence between an autosome and a sex chromosomes?
An auto-some is any of the 23 chromosomes which is not an X or Y chromosome. A sex chromosome is effectively the same as an auto-some, apart from depending upon whether you inherit a Y chromosome or not, a sex chromosome will determine your gender. Hence the name. -By SciienceFreak
How is a pedigree?
A pedigree is used to determine whether you are at risk of inheriting a particular genetic disorder.
Does crossing over produces chromosomes that carry genetic information from both homologous chromosomes?
The question is not proper. Please define more. I assume you meant whether the genetic information is transferred between homologous chromosomes. Yeah it does. When the two homologous chromosomes pair up to form bivalents, crossing over occurs between them.
What special information is contained in chromosomes?
Chromosomes contain the genetic information that determines an organism's traits, such as its physical characteristics and biochemical functions. They also play a crucial role in transmitting this genetic information from one generation to the next through the process of cell division.
What does a genetic counselor construct to show the inheritance pattern of a genetic disorder within a family?
Its a pedigree. A pedigree shows the inheritance of a genetic disorder within a family and can help to determine the inheritance pattern and whether any particular individual has an allele for that disorder.
What is a pair of chromosomes carrying genes that determine whether a person is male or female?
Genetic chromosomes

How chromosomes determines whether and child is male or female?
Females have two X chromosomes. Males have one X and one Y.
