1.A Black Chicken (Bb) And A White Chicken (Ww) Were Crossed. Predict What The, Outcome Of The Cross. Key: Bb (Black) Ww (White), Bw (Checkered), A. B

1.A black chicken (BB) and a white chicken (WW) were crossed. Predict what the

outcome of the cross. Key: BB (black) WW (white)
Bw (checkered)
A. BB
B. B
C. Bw
D. WW
2. crossed was done between homozygous red flower and white flower. Predict the
phenotype of the cross.
A. 2 red, 2 white
B. 3 red. 1 white
C. 4 white
D. 4 red

1. using the punnett square

            B          B

W        BW       BW

W        BW       BW

since both have homozygous traits each can have a black feathered and white feathered color of chicken, and that is called a codominance.

2. again using the punnett square

            R           R

W        RW        RW

W        RW         RW

which states that 4 of them can either be white or 4 of them would be red due to again codominance so if the dominant trait is red flower then probably all the flowers can be red but in the other hand since the offsprings are heterozygous then it can also be white given that red is dominant and white is recessive.
