Which response to different environmental conditions would you expect from a species that has a high VG×E for a trait? All genotypes respond similarly to environmental conditions. The magnitude of each genotype's response is always similar. Different genotypes have varying responses to different conditions. The same genotype will have the same response to different conditions.

Flower color variation in Phlox drummondii living either in sympatry or allopatry with Phlox cuspidata has previously been studied. Phlox drummondii exist in four colors: light blue, dark blue, light red, and dark red. Each flower color is controlled by a specific combination of alleles. In allopatry, butterflies randomly pollinate Phlox drummondii flowers of all color types. In contrast, non-random pollination occurs between differently colored flowers when both Phlox species are living in sympatry. The graph depicts the relative fitness of the alleles that drive flower color in Phlox drummondii under conditions of sympatry or allopatry with Phlox cuspidata. Label each half of the graph with the term sympatry or allopatry based on the observed trend in the relative fitness of the alleles that control all four flower colors in Phlox drummondii.
Which of the following is an example of environmental impacts on the expression of traits? Heterozygous individuals of a plant species have pink flowers, whereas homozygous individuals have either red or white flowers. An individual’s blood type depends on the interaction of the alleles A, B, or O. Animal coat color shifts in response to seasonal changes in day length and temperature.
In garden pea plants, the yellow seed colour (Y) is dominant over the green seed colour (y). In a population of 24 pea plants, 15 pea plants are homozygous dominant, 6 are heterozygous dominant, and 3 are recessive. Find the frequency of the following YY, Yy, yy. Show all work and record your response using three significant digits.
Which of the following statements about the theories of senescence is correct? Question 2 options: The reason why organisms become old and decrepit is because an individual would often have accumulated too much energy in its lifetime in the form of fat reserve; therefore, an older individual often dies from old-age related diseases. An allele that shows its deleterious effect later in life will always have a smaller impact on an organism's fitness than an allele that shows its deleterious effect early in life. Therefore, late-acting deleterious mutations can be fixed in the population, resulting in shortened lifespans. The allele that can result in early reproduction will always be selected for, even if it comes with a cost of earlier senescence. Typically, for species that live fast would usually die young. None of the above
A new kind of tulip is produced that develops only purple or pink flowers. Assume that flower color is controlled by a single-gene locus and that the purple allele (C) is dominant to the pink allele (c). A random sample of 1000 tulips from a large cultivated field yields 847 purple flowers (out of which 476 are heterozygous) and 153 pink flowers. If p = frequency of C allele and q = frequency of the c allele. Calculate p and q. A. p = 0.4 q = 0.6 B. p = 0.61 q = 0.39 C. p = 0.847 q = 0.153 D. p = 0.82 q = 0.18
A gardener grows two different colors of apples under exactly the same environmental conditions. Red apples have a heritability of 0.14 for the value of apple weight, and green apples have a heritability of 0.41 for the value of apple weight. The gardener plotted the number of apples present at each weight. Which graph would you hypothesize represents the red apples? Number of apples Weight GRAPH A Number of apples Weight GRAPH B O Graph A O Graph B There is not enough information to make a hypothesis.

heritability was published in 2009 in the International Journal of Obesity. This study uses data from the "FinnTwin16" study in which nearly all twins born in Finland from 1975-79 are being tracked for many phenotypes. The table below reports correlation coefficients (rmz and dmz) separately for male and female twin pairs at about 30 years of age for 3 traits: BMI, waist circumference, and level of physical activity (the study investigated the relationships between these traits). Calculate H² for each trait and sex using the strategy discussed in Video 4.4. Match the your values with the appropriate trait and sex.

Which of the following BEST describes the relationship between genotype, phenotype, traits, and the environment? O Organisms acquire traits during their lifetime that alter their phenotype. This allows individuals to better adapt to their surroundings, and to pass on their phenotypes to their offspring regardless of their genes. An organism's phenotype is largely determined by its genes, or genotype. The relationship between an organism's phenotype and its environment determines the frequency of traits in a population. O The relationship between an organism's environment and its genotype determines the type of phenotype it will develop. Phenotypes are largely determined by the environment and organisms display traits that are unrelated to their genes.
in considering the interaction of multiple genes involved in complex traits and interaction with the environmental factors what does the organisms genotype represent? What does the phenotype represent? What does the environment have to do with it?
