What would represent a colorblind male in a pedigree?
In a pedigree, a colorblind male would be represented by a shaded square, indicating that he possesses the trait of colorblindness. This symbol is usually used to show a genetic condition or trait that is being traced through the family tree.
How many genotypes are possible in a pedigree of sex linked traits?
In a pedigree of sex-linked traits, there are three possible genotypes for males: XY (unaffected), XeY (affected), and XeX (carrier). For females, there are two possible genotypes: XX (unaffected) and XeX (carrier). This makes a total of 5 possible genotypes in a sex-linked trait pedigree.
Discuss the inheritance pattern that would be seen in a pedigree designed to study a recessive sex-linked trait?
In a pedigree designed to study a recessive sex-linked trait, affected individuals are more commonly male because they inherit the trait on their X chromosome from their carrier mother. Females need to inherit two copies of the gene (one from each parent) to be affected. The trait skips generations and can be passed down from carrier females to affected males.
What is the genotype of an affected male on a pedigree?
An affected male will typically have one copy of the disease-causing allele, often represented as "X^A Y" for X-linked recessive disorders or "Aa" for autosomal dominant disorders on a pedigree chart. This genotype indicates that the male has one copy of the mutated gene leading to the disease.
In a pedigree the squares are used to represent what?
Squares represent males, and Circles represent females
What would represent a colorblind male in a pedigree?
In a pedigree, a colorblind male would be represented by a shaded square, indicating that he possesses the trait of colorblindness. This symbol is usually used to show a genetic condition or trait that is being traced through the family tree.
In a pedigree what does it mean if a symbol is colored in?
In a pedigree, a colored symbol typically indicates that an individual is affected by a specific genetic condition or trait being studied. For example, a filled circle may represent an affected female, while a filled square may represent an affected male. This visual representation helps to easily identify patterns of inheritance and the distribution of the trait within families.
How is an infected male represented on a pedigree chart?
An infected male may be represented by shading in the symbol indicating his sex on a pedigree chart, or by using a different color or pattern in the symbol. This helps to visually indicate his status as infected with a particular condition or disease being studied.
Does a circle on a pedigree represent a male?
No, a circle on a pedigree typically represents a female. A square is used to represent a male in a pedigree chart.
How many genotypes are possible in a pedigree of sex linked traits?
In a pedigree of sex-linked traits, there are three possible genotypes for males: XY (unaffected), XeY (affected), and XeX (carrier). For females, there are two possible genotypes: XX (unaffected) and XeX (carrier). This makes a total of 5 possible genotypes in a sex-linked trait pedigree.
Why would we color in a square or circle in the pedigree chart?
In a pedigree chart, coloring in a square (representing a male) or a circle (representing a female) typically indicates that the individual has a particular trait or condition of interest, such as a genetic disorder. This visual representation helps to easily identify affected individuals and track the inheritance patterns of the trait through generations. It also aids in analyzing the likelihood of the trait being passed on to future offspring.
What is the Shape used for a male in pedigree?
square
How is a male shown on a pedigree?
In a genetic pedigree, males are represented by squares while females are represented by circles.
What is the pedigry?
A pedigree is a diagram of family relationships that uses symbols to represent people and lines to represent genetic relationships.Pedigrees make it easier to visualize relationships within families are often used to determine the mode of inheritance of genetic diseases.Symbols in pedigree:Squares represent males and circles represent females.Horizontal lines connecting a male and female represent mating.Vertical lines extending downward from a couple represent their children.If the purpose of a pedigree is to analyze the pattern of inheritance of a particular trait, it is customary to shade in the symbol of all individuals that possess this trait.

Females need to inherit two copies of the gene (one from each parent) to be affected. The trait skips generations and can be passed down from carrier females to affected males.
A male will always transmit a recessive trait to his son?
no not always they can transmit a dominate trait also
What inheritance pattern in a pedigree would allow you to decide that a characteristic is Linked?
"Any trait that showed up in the males only would be considered to be sex-linked to the X chromosome. This is because a male being XY would show the effect and the females who were carriers being XX would obviously have the normal ( non mutant ) X chromosome too, which dominates the mutated one. A classic example of X linked ( sex linked) traits is Haemophilia who are nearly always male. But a female haemophiliac is possible but could only be produced from having a haemophiliac father and a carrier mother ( A rare combination) and therefore inheriting two copies of the mutated recessive x "bleeding" gene. Hope this helps." -From blurtit.com
