In erminette chickens, the gene for feather color has two codominant alleles-one for black feathers and one for white feathers heterozygous chickens have both black and white feathers resulting in a distinctive speckled feather answer key

1. Cross a black chicken and an Erminette chicken. Parental Genotypes X
Offspring Genotypic Ratio:
Offspring Phenotypic Ratio:

2. Cross a white chicken and a black chicken.

the answer is a) y= 2 csc [0.5 (x+pi/2)]-1

step-by-step explanation:

step-by-step explanation:

rectangles are made up of 4 right angles, which means that a side and a base meet perpendicular to one another.   their slopes then have to reflect perpendicular slopes.   perpendicular slopes are opposite reciprocals of one another.   for example, if the slope of one line is +2/3, then the perpendicular slope to that would be -3/2.   so we look for that combination in our choices.

all of them satisfy that condition (so what's the question, i guess? )
