Direction: In the following questions a statement of assertion (A) is...
Assertion (A) : Grasshopper shows male heterogamety.
Reason (R) : In grasshopper, males have one X only (XO type).
The correct answer is option 'A' - Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A).
Explanation:
Let's break down the assertion and reason statements to understand why the correct answer is option 'A'.
Assertion (A): Grasshopper shows male heterogamety.
In genetics, heterogamety refers to the condition where the sex chromosomes of males and females differ. In grasshoppers, the sex determination system is based on the presence or absence of a sex chromosome called the X chromosome.
Reason (R): In grasshopper, males have one X only (XO type).
In grasshoppers, males have one X chromosome and no Y chromosome, which is referred to as XO type sex determination. The absence of a Y chromosome in males means that they do not possess the typical XY sex determination system found in many other organisms.
Explanation:
Grasshoppers exhibit a type of sex determination called XO type, where males have one X chromosome and no Y chromosome. This is in contrast to the typical XY sex determination system found in humans and many other organisms, where males possess one X and one Y chromosome.
In grasshoppers, the presence or absence of the X chromosome determines the sex of an individual. Females have two X chromosomes (XX), while males have only one X chromosome (XO). This makes the grasshopper sex determination system an example of male heterogamety, where the sex chromosomes of males and females differ.
The reason given in the statement (R) provides a correct explanation for the assertion (A). The fact that grasshopper males have one X chromosome only (XO type) is the reason why grasshoppers exhibit male heterogamety. Therefore, both the assertion and reason are true, and the reason correctly explains the assertion.
In conclusion, the correct answer is option 'A' - Both assertion (A) and reason (R) are true, and reason (R) is the correct explanation of assertion (A).
Reason (R) : In grasshopper, males have one X only (XO type).
The correct answer is option 'A' - Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A).
