The selection that acts over evolutionary time to preserve traits that increase an individual's ability to mate is known as se_xual selection.
<h3>What is se_xual selection?</h3>
The expression 'se_xual selection' makes reference to the type of evolutionary constraint on the individual's ability to mate.
Se_xual selection is fundamental to increase the genetic variation and thus enhance adaptive chances.
Se_xual selection can be considered a special type of natural selection that acts at an individual level.

Answer:
The genotypic frequency = 1:1
The phenotypic frequency = 1:1
Explanation:
Given that:
The allele → R = Red beetles
The allele → B = Blue beetles
Since the gene color shows a codominant allele
The Red Beetle = RR
The blue beetles will be = BB
The heterozygous beetle will be = RB
∴
The punnet square showing the crossing of RB × RR is:
R B
R RR RB
R RR RB
The result shows that we have two red beetles and two heterozygous beetles.
Hence;
The genotypic frequency = 1:1
The phenotypic frequency = 1:1
Answer:
D
Explanation:
The answer to his question (which detergent is best) is that the one that removed all stains was the best.
Answer:
150.
Explanation:
150 flies are expected to have normal body color and to be eyeless in F2 generation. The reason for that population is the ratio of the species produced. The ratio of the species are 9:3:3:1. Ratio 9 refers to first parent while 1 refers to second parent and the middle 3's represent the hybrid formed. So the population of first parent is 450 and population of second parent is 50 while the population of two hybrids are 150 each.
