Answer:
Grey Mice have a higher fitness because their phenotype allows them to blend in with their environment, thus helping them to avoid predators. This allows them to survive and reproduce better than the other mice.
A because it’s dna fragments
Answer:
E.
Explanation:
The first filial generation, will have 4000MN, while the progeny of the new Haldane population will be in the second filial generation 1000 MM + 2000 MN + 1000 NN.
Answer:
12-day litter weight is a trait that has an important genetic influence and therefore also a high response to selection
Explanation:
Heritability is a statistical measure of how much of the variation in a given trait can be attributed to genetic differences and how much of trait variation is due to environmental factors. A heritability value close to 1 indicates that almost all of the variability is due to genetic factors, while being poorly influenced by environmental factors. In this case, 12-day litter weight is a trait that exhibits an important genetic component (i.e., a high heritability value), thereby the correlation between parent and offspring will be high and lines selected for this trait will show a high response to selection.
Answer:
Shadows are made by blocking light. Light rays travel from a source in straight lines. If an opaque (solid) object gets in the way, it stops light rays from traveling through it. This results in an area of darkness appearing behind the object. The dark area is called a shadow
