Answer:
Both parents have a genotype of Tt
Explanation:
Let's say the genotype for tall is T and the genotype of short is t
When the plants are crossed, it looks a little like this:
<u> I T I t I</u>
<u>I T I TT I Tt I</u>
<u>I t I Tt I tt I</u>
The lower case tt represents the dwarf plants
Hope this helps :)
Answer:
FfPp
Explanation:
If we take the two traits to be separate alleles, we can make flowers F (F is dominant; f is recessive) and pollen as P (P is dominant; p is recessive). So a pea plant with white flowers (recessive) and long pollen (dominant) will have the genotype ffPp or ffPP (because one dominant allele will express a dominant phenotype).
For this question, we will assume that the wild type (red flowers and long pollen) is homozygous, meaning it contains two dominant alleles.
If the wild type (FFPP) is crossed with the plant with white flowers and short pollen (ffpp), we can make a table illustrating the crosses. However, because there is only one possible gamete that each parent can form (FP and fp), we can assume that the F1 progeny will have identical genotypes, which can be expressed as FfPp (because combining the gamete from the wild type and the other parent can only give one phenotype).

Primary succession is beginning.
Primary succession is when a disaster destroys the environment, leaving no soil and no organisms left. This is evident by the bare rock. Lichens are a pioneer species, meaning they are one of the first organisms that show up.
