Because alleles can be either dominant or recessive. For example eyes : brown dominant and blue recessive. The mom can have Bb which is dominant and recessive and the dad can have bb only recessive. There’s going to be a combination of alleles which leaves the outcome unknown. The offspring can inherit either: Bb or bb

Answer:

Each parent organism contributes one copy of its alleles in a seemingly random fashion to its offspring, as meiosis to create gametes (egg or sperm cells) reduces the number of genes by half. Therefore, each gamete contributes only one allele.

The diagram shows a simple lipid.
Evgesh-ka [11]

The correct answer is option A, that is, saturated.

The mentioned lipid is not a phospholipid, as it does not comprise a phosphate group at the terminal of the chain, and is not a triglyceride due to the absence of glycerol moiety.

Each carbon combined with the hydrogens forms the maximum number of possible C-H bonds, thus, there are no multiple bonds between the carbons. Hence, it can be concluded that the lipid is saturated.

Consider the data on cliff swallow mortality. Why is this an example of directional selection?Overall genetic variation decrease
Gala2k [10]

Answer:

The average trait value changed in one direction.(In this case, larger size)

Explanation:

In evolution a natural selection can be disruptive, directional or stabilizing

In stabilizing no extreme trait is favored hence provides intermediate values .

Disruptive selection both extreme traits are favored over the intermediate trait.

Directional, the enviroment will favor the survival of one trait hence a change in direction either towards the left or the right.

In the case of swallow cliff mortality, selection favored the larger size.
