Question

Which is a dominant trait?
A. Colour blindness
B. Albinism
C. Haemophilia
D. Rh+ factor

Answer 1

Hint: The trait which can communicate its impact over differentiating traits is known as a dominant trait. It is communicated even within the sight of one duplicate of an allele for a specific character in the quality, i.e., it is communicated in the heterozygous condition. Example: Yy speaks to the dominant trait for yellow seed tone. The seed is yellow in any event when a single duplicate dominant allele Y is available.

Complete answer:
Rh disease happens during pregnancy. It happens when the Rh factors in the mother's and child's blood don't coordinate. It might likewise occur if the mother and child have diverse blood classifications. Rh is a dominant allele. So, option D is correct.
Color blindness is inherited as a recessive trait on the X chromosome. This is referred to in hereditary qualities as X-connected recessive legacy. Accordingly, the condition will in general influence guys more regularly than females (8% male, 0.5% female). So, option A is incorrect.
Hemophilia is a sex-connected recessive issue. The anomalous quality answerable for hemophilia is carried on the X chromosome. Guys have one X chromosome and one Y chromosome. So, option C is incorrect.
Albinism is inherited in an autosomal recessive example, which implies the two duplicates of quality in every cell have transformations. So, option B is incorrect.
Hence, option D is correct.

Note: Rh factors are hereditarily decided. An infant may have the blood classification and Rh factor of either parent or a blend of the two guardians. Rh factors follow a typical example of a hereditary legacy. The Rh-positive quality is dominant (more grounded) and in any event, when combined with an Rh-negative quality, the positive quality takes over. The rhesus factor is a significant attribute of platelets. It shows whether the blood of two distinct individuals is viable when blended –, for example, the blood of a mother and her child upon entering the world. If they have distinctive blood bunch qualities, it might cause issues.
