If the parent generation consisted of a homozygous dominant parent and a homozygous recessive parent, then the F1 generation would be 100% heterozygous.

Why does natural selection only work on phenotypes?
Natural selection is based on the environment and on the traits of organisms. Organisms with more suitable traits are more likely to survive until reproductive age, while organisms with less suitable traits are more likely to die before they can reproduce. Most of these traits are genetic traits. The phenotype is the set of all genetic traits. Natural selection is not determined by genotypes, because genotypes are merely an organism's genetic makeup. Only the dominant or somewhat dominant alleles in the genotype will also appear in the phenotype. However, genotypes still contribute to natural selection indirectly in that two alleles in two parents' genotypes which had not appeared in their phenotypes could be inherited such that they are in the phenotype of the offspring.
What are the genotypes and phenotypes of a cross between a true breeding tall and a true breeding short pea plant?
The results of the first generation were 3 tall plants and 1 short plant, indicating that some activity was making the tall plants more likely, but not exclusively so.
What are inherited traits that its offspring will most likely inherit for butterflies?
color
Does sexual reproduction alone cause evolution?
This is a tricky question. To some degree, yes but it's more complicated than that. Individuals with adaptive (useful for survival) traits are more likely to find a mate than those without them and their offspring are more likely to survive than the offspring of those without the traits. Their offspring will also be more likely to find mates and more likely to produce offspring and this continues down the line, making more and more of the population have the adaptive trait.
What is most likely to alter the DNA in an individual's gametes before it is passed to an offspring?
Poor Nutrition
A cross between two pea plants that produce yellow seeds results in 124 offspring 93 produce yellow seeds and 31 produce green seeds what are the likely genotypes of the plants that were crossed?
Yy
What was the genotype of the offspring the did not share the parents' phenotype?
If both parents have the same phenotype, but the offspring did not share that phenotype, then it is likely that the parents have a dominant phenotype, but the offspring has a recessive phenotype, which means that the offpring's genotype would be homozygous recessive, and it's parents' genotypes would be heterozygous. For example, the parents may both have the genotype Bb, which gives them black fur. Approximately 25% of their offspring should have the genotype bb, which gives them the phenotype of white fur.

What percentage of the offspring will most likely show the dominant trait?
More information is needed. The percent of offspring that will display the recessive trait from parents with Hh and HH will be different than the percent of offspring that will display the recessive trait from parents with hh and Hh.

What would most likely describe the population of offspring?
The majority of the offspring population has functioning wings.
What is likely to occur when an endangered species has low offspring numbers?
Extinction is likely.
How does evolution explain morality?
Natural selection has selected the morality we have today, its built In to our instibt to understand eachothers emotions, facial expressions etc, natural selection favours a species with a good morality as this increaaes the survival of offspring, the offspring will normally have the same morality and understanding of emotions and thus pass it on from generation to generation, those that weaker morality would have not been able to reproduce as succesfully as the offspring would have had less help from the others in the community if any, and woud be less likely to make it to adulthood and reproduce,

Does Clark gillies have offspring likely to make NHL?
no
What is the similarity asexual and sexual reproduction?
The only major similarity is that you get a type of offspring. During asexual reproduction, an organism essentially self mates. This doesnt necessarily produce identical offspring, but close. Actually, with asexual reproduction, mutations are more likely to be phenotypically present in the next generation. So technically, you get offspring that does share genes from dad and mom, but in asexual reproduction, dad and mom are the same people.
What characteristic is a lion least likely to pass on to its offspring?
