Biology
1 answer:
Ratling [72]3 years ago
7 0

The question is incomplete and the complete question has been attached.

Answer:

The genotype of the Alice is ee.

Explanation:

In the given question that Alice has unattached earlobe which is a recessive trait. The trait is recessive therefore the trait is determined only when both the copies of the allele is present.

The allele for attached earlobe (dominant) is E and unattached earlobe ( recessive) is e.

The recessive condition means the trait will be expressed when ee condition is present therefore the Alice will have the ee genotype. This condition is present only in the second punnett square.

Thus,the genotye of Alice is ee.

I need help with the image (phenotypes and genotypes).
Flauer [41]

Answer:

See the answer below

Explanation:

1. <u>Only one phenotype</u> is present in the F1 generation offspring. Since tallness was dominant over shortness, all the offspring in the F1 generation appeared tall.

2. <u>Two phenotypes </u>are present in the F2 generation - 9 tall and 3 short. The short trait reappeared at the F2 generation.

3. The genotype of the F1 offspring would be heterozygous. Assuming the purebred tall is AA and the purebred short is aa:

     AA   x   aa

  Aa   Aa   Aa   Aa

All the F1 offspring will appear tall and their genotypes would be heterozygous.

4. Assuming that the allele for height is denoted with A (a), <u>the genotype of the purebred tall plant would be AA. </u>

5. In a similia vein, <u>the genotype of the purebred short plant would be aa. </u>

8. Why is the active site specific for only one type of substrate?
Ksivusya [100]
Why is the active site specific for only one type of substrate? Enzymes have a lock and key type fit so only a specific substrate fits in the activation site.
