Which of the following phenotypic classes reflect offspring that were generated as a result of a recombination event?
babymother [125]

Answer:

The correct options are: A " vestigial wings, red eyes" and D "full wings, purple eyes"

Explanation:

female parent: vg+pr+/vg pr

(phenotype - full winged and red eyes)

male parent:  vgpr/vgpr

(phenotype - vestigial winged and purple eyes)

Of these traits, vestigial wings and purple eyes are recessive traits. Hence, when a recombination event occurs, the offspring can potentially have a wild type trait paired with a recessive trait.

Why and how is depression the biggest diagnostic in the U.S
SVETLANKA909090 [29]
This is because the modern lifestyle we're living and people are living in the US is very taxing and can cause people to feel extremely bad about themselves for prolonged periods of time. Furthermore, it's also possible people/doctors are misdiagnosing depression and saying someone is depressed when he or she actually isn't.

When both participants in a species' interaction develop adaptations in direct response to one another, this could progress into
fomenos

Answer:

coevolution

Explanation:

Coevolution refers to the process where two or more species modify each other's evolution via natural selection. Darwin mentioned how insects and flowering plants could coevolve by reciprocal evolutionary modifications. Coevolution has firstly been associated with mutualism between species including, for example, birds and flowering plants. However, coevolution may also involve host-parasite relationships, such as associations involving parasitic organisms and their sexually reproducing hosts. Finally, there are situations where coevolution involves both parasitism and mutualism (i.e., antagonistic coevolution).
