In chickens, white feathers (W) are dominant to black feathers (w) Two chickens are crossed and 50% of their offspring have black feathers. Which cross represents the genotypes of the parents? wwxww wwxww Ww x ww WWtimes WW

The correct answer is: Ww x ww.<br /><br />Explanation: In this scenario, the dominant allele for white feathers (W) is present in one parent (Ww), while the recessive allele for black feathers (w) is present in both parents (ww). When these two chickens are crossed, the offspring will have a 50% chance of inheriting the recessive allele (w) from both parents, resulting in black feathers. Therefore, the cross that represents the genotypes of the parents is Ww x ww.
