Firstly, start by doing Punnett squares for each of the characteristics. Attached are the three Punnet squares, made by me, as they should look in end.
For each of the Punnet squares, one characteristic each, we find that half of the offspring will be heterozygous for that characteristic.
Therefore, according to the product rule, you should now multiply the quantity of heterozygous for each characteristic and then obtain the total part of the offspring that's fully heterozygous.

Ss×

Ll×

Rr=

SsLlRr
Total offspring×

=10
There is 10 plants in the total offspring that are heterozygous for all the considered three genes.
Answer:
<h3>2. Human height is determined by several genes located on different chromosomes.
</h3><h3>3. A person with AB blood type.
</h3><h3>4. Hydrangea flower color varies with soil pH.
</h3>
Explanation:
2. Polygenic ( poly- many) traits are the genetic traits that are governed by several genes. Human height is one such example. Other examples in humans are skin color, eye color, etc.
3. There are 3 alleles responsible for the blood type in humans, which are
- Ia- the dominant allele that produces Antigen A on the surface of RBC.
- Ib- the dominant allele that produces Antigen B on the surface of RBC.
- Io - the recessive allele that doesn't produce any antigen.
Thus, when both the alleles for A blood type and B blood type are present, both are expressed as A and B antigens on the surface of RBC because of Codominance (Co- together) thus producing AB blood type.
4. The pH of the soil is an environmental factor. Hence, the change of color based on the soil pH is an example of the environment affecting a genetic trait.
