If the parent genotypes are Aa and Aa is there only two possible genotypes among the offspring?

No, there are more than two possible genotypes among the offspring when both parent genotypes are Aa. The potential genotypes for the offspring are AA, Aa, and aa, resulting in a total of three different genotypes. The expected ratio from a Punnett square for this cross is 1 AA : 2 Aa : 1 aa.


Why isn't it possible to have more genotypes than phenotypes?

I think you have the question backwards, "Why isn't it possible to have more phenotypes than genotypes?" There are always more or an equal number of genotypes relative to phenotypes. The phenotype for a simple dominant/recessive interaction (for example) T for tall and t for short where TT is tall, Tt is tall and tt is short has three genotypes and two phenotypes. If T and t are co-dominant then TT would be tall, Tt would be intermediate and tt would be short. (Three phenotypes and three genotypes.)


What are the three things necessary for a plant to be classified as a tree?

Three things necessary for a plant to be classified as a tree are having a single main stem or trunk, growing to a height of at least 13 feet, and having a defined crown or canopy of foliage.


what besides flower color are three characteristics of pea plants that Mendel studied?

Besides flower color, Mendal studied seed shape, pod color, and plant height.


A person with phenotype A blood has how many possible genotypes?

Although there are actually several genes which determine ABO-type, they are usually placed into the three basic groups i.e. A, B and O.For each phenotype, the genotypes follow:O: OO is the only possibility.A: AA or AO are both acceptable.B: BB or BO are both acceptable.AB: AB is the only possibility.

If a plant one grows a foot a day and plant two grows two feet a day in how many days will plant two be three times the height as plant one?

This won't ever happen, it is impossible.

What are multiple-allele traits?

Traits governed by multiple alleles are controlled by three or more alleles, rather than two. An example in humans is the ABO blood group system. There are three alleles in the ABO blood group system, IA, IB, IO. These three alleles can produce six genotypes, AA, AO, BB, BO, AB, OO. These genotypes can produce four different phenotypes, A (genotypes AA or AO), B (genotypes BB or BO), AB, (genotype AB) and O (genotype OO).


How deep should I plant bulbs to ensure successful growth and blooming?

Plant bulbs at a depth that is about three times the height of the bulb. This will help ensure successful growth and blooming.

In geometry a soils may exist in three dimensional space?

Yes, in geometry, the concept of space includes three dimensions: length, width, and height. Soils, as physical entities found on Earth, also exist in three dimensions. This means that soils have depth, width, and length, making them three-dimensional objects.


What is the average height of three year old?

What is a 3 d shape?

A 3D shape stands for Three-Dimensional. The three dimensions are Height, Width and Depth. A line just has height, so it is 1D. A polygon has both Height and width so it's 2D. A three dimensional object has all three; Height, Width and Depth.________^Height/Length = 1D-------------------| || | Depth |/ |----------------- |
