Which cross will yield four phenotypes in the ratio?
A phenotype is the composite of an organism's observable traits. The answer to the question, the cross that will yield four phenotypes in the 1:1:1:1 ratio is fifty.
Which statement best predicts the results of the cross MmDdPp x mmddpp assuming that all three genes are linked?
All eight possible phenotypes could occur, but a greater proportion of the offspring would have the parental phenotypes.
Can you determine whether an allele is dominant or rescessive on the basis of the ratio of the phenotypes in the population?
no. Yes, it is possible in a test cross
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.)
How many phenotypes does the trait have?
Aa AA aa If A dominant, two phenotypes.

What phenotypes resulted from the hybrid cross?
cell
If you cross a while flower with the genotype pp with a purple flower with the genotype pp the possible genotypes in the offspring will be what for the cross what would the phenotypes be?
half white and half purple

What would be the genotypes and phenotypes of the P1 and F1 generations?
i love ian somerhalder, justin bieber, cody simpson, nick roux, mindless behavior, randy orton, eminem, mgk, john morrison, paul wesley, nina dobrev, michael trevino, candice accola, demi lovato, and selena gomez!!(:

What phenotypes are present in F1 generation?
The phenotypes present in the F1 generation depend on the phenotypes of the parental generation (and the environment). The F1 generation will display the dominant trait(s). For example, if T is tall and t is short, in the cross TT X tt the F1 generation will have the phenotype corresponding to the T allele (tall).

Why do human traits such as height and skin color have different phenotype?
This is because phenotypes are the physical appearance. If you had brown hair and so did I, our phenotypes, would still be different.
What are the likely phenotypes of these seeds when they germinate?
about one-fourth will be white and three-fourths green since it is similar to a monohybrid cross between heterozygotes
How could a farmer increase the number of genotypes and phenotypes present in his next apple crop?
Cross plants that have very different characteristics
