I need help with the image (phenotypes and genotypes).

Biology
1 answer:
Flauer [41]3 years ago
5 0

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>

Naddika [18.5K]

Answer:

The moths were typically white with black speckles, which helped them blend in. There was a mutation that caused some of them to be almost entirely black, which would make them easier to spot and get eaten. However, one event that left the trees covered in ash and soot was an advantage for these moths. They blended into the trees more so than the other ones, and there was a giant fluctuation of them. The mutated ones now had a better chance of staying camofluaged, and the white and black speckled ones were more likely to get eaten.

vovikov84 [41]

Answer: Ascorbase a form of ascorbate, a drug used in the treatment of type 2 diabetes which acts to inhibit maltase a membrane bound enzyme that completes the digestion of starch in the human body.this inhibition is done through;

- By preventing substrates from binding to the active site therefore forming few enzyme complex substrates.

- it also inhibits the enzymes by binding to the active sites of that enzyme.

- it also does so by reacting slowly and also because it has a complementary shape to the active site of the enzyme maltase.
