A.
Commuters drive personal vehicles to their places of work: offices, manufacturing plants etc.
Some may use car pooling or mass transit like buses. But too many want the luxury and convenience of coming and going on their own terms.
IMHO car pooling and mass transit needs to be used more to reduce environmental harm.
Answer:
The ear length will be 11 cm.
Explanation:
To know about the ear length of F1 generation, we need to know that how much length in centimeters is contributed by each of the alleles. As we know, each allele has the same value for contributing to the effect of ear length, hence we can divide the ear length by 4 to get our results.
As 6 divided by 4 is 1.5 hence, the allele a and b contribute to 1.5 cm of the length of the ear.
6 divided by 4 is 4, hence the alleles And B contribute to 4 cm of the length of the ear.
The F1 generation will have AaBb genotype hence, the lenght will be 4+1.5+4+1.5 = 11 cm.
