These genes are either y-linked if found on the y chromosome or x-linked if found on the x chromosome. Since males only have one x chromosome (xy), in x-linked recessive traits, the phenotype is fully expressed. However, in x-linked dominant traits, both males and females who have an abnormal.
Sex traits can be categorized into three types of inheritance sex-limited, sex-linked, and sex-influenced. Sex-limited traits are traits that are visible only within one sex. For instance, barred coloring in chickens normally is visible only in the roosters. Sex-linked traits would be considered traits like sickle cell anemia and color blindness.
В while this video only focuses on solving sex-linked trait problems in a punnett square, here are some further reading suggestions to learn about the sry gene and its role in biological sex.
В sex-linked traits are associated with genes found on sex chromosomes. Because the x-chromosome is larger, x-linked traits are more common than y-linked traits.
Sex-linked character, observable feature of an organism controlled by genes on the sex chromosomes. In humans, the x (female) chromosome carries many genes, whereas the y (male) chromosome is deficient in genes. Red-green color blindness and hemophilia are examples of sex-linked traits in humans.
