A) 9/16 will have brown eyes and red hair

B) 9/16 will have blue eyes and red hair

C) 3/16 will have blue eyes and brown hair

D) 3/16 will have blue eyes and red hair

Answer 1

Answer #1

Dominant gene for eye colour - B recesive gene for eye colour ab Domirant hair coloux Xene - H. recessive hair colour xene - coloured So Brown exed brown hair will be = 1BB HH - RBLHH + 4 Bbth. 09 +2BB Hb = 9. 3 ONA O L Blue eye Brown eyed red hair w so C option will be the answer.

Uption 4. The inheritance of hair and eye color is very complicated. Scientists have found approximately 10-20 genes responsible for determining hair and eye color in humans (sheesh - I thought a dihybrid cross with 2 genes was bad...). Although many genes are involved in producing these phenotypes, it does seem that just a few genes play a major role in determining the color of our hair and eyes. The following is a simplified, but still somewhat realistic view of...

In wolves, gray coat color (G) is dominant to black (g) and brown eyes (B) are dominant to blue (b). The genes that control these traits are located on different chromosomes. The alpha male of the pack has the dominant phenotype for both traits and is heterozygous for both traits. The alpha female has brown eyes and a black coat; she is heterozygous for eye color. Which option represents gametes that would be made by the alpha female? B. b,...
