Question

the absence of the sry gene will result in: a) external genitalia of a female; internal genitalia of a male b) A phenotypic female c) and intersex individual d) A phenotypic male e) external genitalia of a male; internal genitalia of a female

Answer 1

The correct answer is option b.

Step-by-step explanation:

Sex determining Region of the Y chromosome gene or sry gene is a important gene found on the Y chromosome which is responsible for testis development or so the male characteristic. An XX individual with the SRY gene of the Y chromosome, will develop as male.

Hence, Absence of SRY gene will not result in phenotypic male So,option d is not correct. intersex have male characteristic so option c is not correct.

Absence of SRY gene will lead to development of phenotypic female due to form ovary and Fallopian tube in absence of this gene

Hence, option B is correct
