Question 1 of 5
HARDAn agricultural scientist is developing a new crop variety that combines high yield from one parent variety with disease resistance from another parent variety. After crossing these two varieties, the scientist grows the offspring and selects plants showing both traits, then breeds these selected plants for several more generations. If the high yield trait is controlled by genes 'YY' (homozygous) and disease resistance by 'RR' (homozygous), and both traits are on different chromosomes, what proportion of the F2 generation (second filial generation) will show BOTH high yield and disease resistance in homozygous form?
