Question

when a carrier anaemic female is married with anaemic male.what is the % of anaemic progeny?

Answer 1

50%. This ca be found by simply crossing a carrier female (say XX_c) with an affected male (say X_cX_c). Half of the progeny will be carrier and half will be affected i.e. anaemic.
XX_c​ x X_cX_c
$\downarrow$
XX_c​​ XX_c​​ X_cX_c​​ X_cX_c​​
