If you cross f1 with another f1 what is the genotype and phenotype do you expect in F2 generation?
When you cross two F1 individuals (both being heterozygous for a trait, for example, Aa), the expected genotype ratio in the F2 generation would be 1 AA : 2 Aa : 1 aa. The phenotype ratio, assuming A is dominant over a, would typically be 3 dominant phenotype (AA and Aa) to 1 recessive phenotype (aa). Therefore, you would expect three individuals displaying the dominant trait for every one individual displaying the recessive trait in the F2 generation.

What kind of phenotype ratio would you expect from a mono-hybrid cross?
possible mendelian ratios for monohybrid cross genotype is 1:2:1 and phenotype is 3:1
What type of ratio would you expect in the F2 sporophyte generation if two traits were being followed?
In the F2 generation, you would expect a dihybrid ratio of 9:3:3:1 if two traits are being followed. This ratio comes from the segregation and independent assortment of alleles during gamete formation and fertilization according to Mendel's principles.
How many individuals would be expected to show that a trait in a F2 generation consisting of 80 individuals?
In a F2 generation of 80 individuals, you would expect about 3 individuals to show a trait that follows a typical Mendelian inheritance pattern with a 3:1 ratio in the offspring generation. This is based on the expected ratio of 1:2:1 for a heterozygous cross.
What metabolic processes would you expect to see in protobionts?
In protobionts, you would expect to see metabolic processes such as energy generation through chemiosmosis or photosynthesis, synthesis of basic building blocks like amino acids and nucleotides, and potentially the beginnings of primitive metabolic pathways for growth and reproduction. These processes would allow protobionts to sustain themselves and potentially evolve into more complex forms of life.
When would you expect mutations to be passed to offspring and when would you not?
Wow, many different aspects to look at here. One big one is if it is in every generation or not. If so, then you have a dominant mutation that will show in every individual with an allele for that gene. If it seems to skip generations then you have a recessive mutation. Basically to answer this question you need to look at your family tree and determine what is going on and if every generation has it, they will have it. If your generation has it, they won't.
What would you expect if you breed or Mate two different true breeding stocks of plants?
If one trait is dominant over the other, then the resulting F1 generation would be expected to have the heterozygous genotype and dominant phenotype.
What kind of phenotype ratio would you expect from a mono-hybrid cross?
possible mendelian ratios for monohybrid cross genotype is 1:2:1 and phenotype is 3:1
Would you expect there to be more children with the dominant phenotype or recessive phenotypewhy?
There would likely be more children with the dominant phenotype because it only requires one copy of the dominant allele to express the dominant trait, whereas the recessive phenotype requires two copies of the recessive allele.
Why does natural selection act on phenotype and not genotype?
Natural selection acts solely on phenotype. However, the probability of certain genotypes can be affected by the probability of a certain phenotype surviving. For example, say all the hawks eat all the dark mice and the dark allele for skin color is dominant (D). The hawk doesn't care whether the dark mice is Dd or DD, they will eat them either way and in the same proportions. This affects the genotypes of the populations because in this case, genotypes of DD and Dd will become less frequent than dd.
If dad has freckles and is homozygous and mom has freckles and is heterozygous what phenotypes and genotypes can you expect their offspring?
Alright, I suppose I will do your homework for you.. Here is your punnet square: F F F FF FF f Ff ff Therefore, 3/4, or 75%, offspring will have the phenotype of having freckles, and 1/4, or 25% will have the phenotype of no freckles. And 2/4, or 50%, of the offspring will have the genotype for homozygous for freckles, 1/4, or 25%, of the offspring will carry a heterozygous trait for freckles, and 1/4, or 25%, of the offspring will have the phenotype for homozygous no freckles.
How do geneticists normally tell whether an organism exhibiting a dominant phenotype is homozygous or heterozygous?
They perform a test cross. A test cross takes the unknown genotype and crosses it with a known homozygous recessive. If the F1 generation is all dominant, then they know the organism was a homozygous recessive. If recessive offspring appear, then the organism was a heterozygote. As an example, consider a gene with two alleles, A and a, with Adominant. Now consider the test cross. The unknown genotype can only be one of two possibilities: AA (homozgous dominant) Aa (heterozygous) In a test cross,the unknown genotype is crossed with a known homozygous recessive. Since there are only two possible unknown genotypes, there can be only two possible results. First, consider the case of the unknown genotype being a homozygous dominant. The cross looks like this: AA X aa Remember that a homozygote for an allele can only produce one kind of gamete. In this case the homozygous dominant can only produce gametes with the allele A in them, while the homozygous recessive can only produce gametes with the recessive allele a in them. This means the F1 offspring can only be ONE genotype; Aa. Therefore, all of the offspring would have the dominant phenotype. Now consider the other possible cross, where the unknown genotype is heterozygous: AaX aa Remember that a heterozygote can produce two types of gametes. In this case, the unknown would produce gametes with the dominant allele A or the recessive allele a. The homozygous recessive would still only produce one kind gamete, with the recessive a allele. Therefore, we expect to see only two genotypes in the F1, Aa and aa, in equal proportions. In either case, only one test cross is needed to tell one immediately the nature of the unknown genotype. If all of the F1 are of the dominant phenotype, then the unknown genotype must be homozygous dominant; if a mixture of phenotypes appears in equal proportion, then the unknown genotype must be a heterozygote.
What should you expect during your 4 months pregnancy?
First. Expect another 5 months.
Is there going to be any iPad 6?
Yes, we expect the sixth generation in the spring of 2015. Start saving today!
What can I expect during my 2nd trimester?
You will have to expect morning sickness, the mood swings to kick in, the fact that you will start to experience cravings is another thing to expect.
What is the phenotype of a flower in a pea plant that is homozygous recessive?
You would expect 1 homozygous dominant, 2 heterozygous dominant and 1 homozygous recessive offspring. This is because each parent has one dominant and one recessive allele. Therefore there is a 75% chance of a dominant phenotype and a 25% chance of a recessive phenotype.
What is another way of saying to look for?
To search, seek, expect, hunt.
