Which of the following Statemets are true for spermatogeesis it do it hold true for Oogeesis ?
( a ) It results in the formation of haploid gametes
( b ) Differentiation of gamete occurs after the completion of meiosis
( c ) Meiosis occurs continuously in a mitotically dividing stem cell population
( d ) It is controlled by the Luteinising hormone (LH) and Follic Stimulating Hormone (FSH) screted by the anterior pituitary
( e ) It is initiated at puberty
Choose the most appropriate answer from the options given below :
( b ) and ( c ) only
( b ) , ( d ) and ( e ) only
( b ), ( c ) and ( e ) only
( c ) and ( e ) only
(a) True for both spermatogenesis and Oogenesis
(b) This is true for spermatogenesis I Primary spermatocyte forms 4 sperms. In Oogenesis, when gametes are formed, they remain arrested at Meiosis - II (Metaphases II)
(c) Meiosis is continuous in Spermatogenesis. In Oogenesis, it is arrested.
(d) This is true for both:
(e) Spermatogenesis initiates at Puberty Oogenesis is before birth
Hence b, c, and, e are true for spermatogenesis and not for Oogenesis
