You are given two true-breeding groups of rabbits. the first group has floppy ears and white coat color. the second group has straight ears and black coat color. when you perform a cross of these two groups to obtain an f1 generation, you see that all of your rabbits have floppy ears and grey coat color. which of the following possibilities appears to be supported by what you see in the f1 generation? a) floppy ears are dominant over straight ears; white coat color is dominant over black coat color. b) straight ears are dominant over floppy ears; coat color is determined by intermediate dominance. c) straight ears are dominant over floppy ears; white coat color is dominant over black coat color. d) straight ears are dominant over floppy ears; black coat color is dominant over white coat color. e) floppy ears are dominant over straight ears; coat color is determined by incomplete dominance. f) floppy ears are dominant over straight ears; black coat color is dominant over white coat color.

Option E, Floppy ears are dominant over straight ears; coat color is determined by incomplete dominance

Explanation:

Let the allele for floppy ears be "F" and the allele for straight ears be "f"

And Let the allele for black coat color be "B" and the color for white coat color be "b"

Now, the cross is carried out between the first group having floppy ears and white coat color (FFbb) and the second group having straight ears and black coat color (ff BB)

The 16 offspring have genotype FfBb

Phenotype of 16 offspring is Floppy ears and grey coat

Ff represents the floppy ear , thus "F" is dominant over "f"

Bb represents the grey color which is a case of incomplete dominance in which none of the real trait i.e black or white is expressed.

Hence, option E is correct

bacteria could be both, harmful and to us. harmful bacteria could make us sick and probably even by getting the chances of getting a disease, but good bacteria fight it off with your immune system. there is always bacteria everywhere we go. we need to make sure to wash our hands after using the restroom, before eating, after eating, after petting an animal too. so you see, bacteria is everywhere and is harmful or . i hope this . : ) : ) : )
