When some organisms are born they can have a blend of the mother and father's physical traits, they can either become codominant or incomplete dominant. Codominance occurs when and organism expresses a blend of the mother and father's traits such as a white and a brown horse giving birth to a white and brown splotched horse. Incomplete dominance occurs when two dominant traits are shown at the same time such as an African American and a Caucasian giving birth to a child with light brown skin.
Represents the chromosomes of a male
Sex chromosomes are the 23rd chromosome for humans which determines if you will be a male or female. chromosomes 1-22 are called autosomes.
Before we are born, we all start off with the XX chromosome, while some keep the XX chromosome, others will have it switch to XY. Males are more likely to show a sex linked trait because the Y chromosome doesn't have the dominant genes that would be able to cover up the recessive genes found on the X chromosome. While occurrences are few and far between, it is also possible for males to carry a Y-linked sex trait that cannot be inherited in females, but is passed down, therefore they will be simply known as a carrier.
