Question

The type of inheritance shown in the following pedigree chart is

A) Autosomal dominant trait
B) Autosomal recessive trait
C) Sex-linked dominant trait
D) Sex -linked recessive trait.

Answer 1

Hint: A pedigree is a visual diagram that depicts a family's history or the transmission of a particular trait. They can be significant and fascinating tools for determining examples of legacy of specific characteristics. These are also used to determine a person's proclivity to transmit a specific genetic disease.

Complete answer:
The square shapes represent the males in the family, while the circles represent the females. If any individual is influenced by a quality, whether latent or prevailing, we conceal the shape. Marriage or association is represented by a line connecting the circle and square. An offspring is demonstrated by the line drawn from the marriage line. A few shapes that are only partially filled show a cross breed or trait carrier. The members in the above family outline age are unaffected by the illness, but the offspring is.
In the event that the problem is latent, neither of the parents must have it because they can be heterozygous. The following are the distinguishing features of autosomal passive inheritance: - Appearance in both genders with equal frequency
In general, traits will skip ages.
Affected descendants are typically born to unaffected guardians.
When both the partners are heterozygous, approximately one-quarter of the descendants will be influenced.
Appearances more frequently among the offspring of consanguineous relationships.
These highlights are followed by the given family.

So 'Autosomal passive attribute' is the correct answer.

Note:
The quality of interest in a family can be either dominant or passive. Most dangerous hereditary conditions can be seen when an individual is homozygous passive. Conditions caused by passive alleles include cystic fibrosis, phenylketonuria, albinism, and others. Polydactyly, achondroplasia, and other hereditary conditions are caused by prevailing alleles.
