If there are 100 individuals in a population and 20 are homozygous for b, 60 are heterozygous, and 20 are homozygous for b, the allele frequency of b is 50%.  

Allele frequency, sometimes referred to as gene frequency, is the percentage or fractional frequency of an allele (gene variant) at a certain location in a population. What is being discussed is the proportion of chromosomes in the population that carry that allele in comparison to the entire population or sample size. The slow change in allele frequencies within a population is known as microevolution.

Taking into consideration:

1. A particular allele at a particular chromosomal region.

2. A collection of N individuals with ploidy n, which denotes that each individual's somatic cells have n copies of each chromosome (e.g. two chromosomes in the cells of diploid species).

If an allele is found in a population on I chromosomes, the allele frequency is the proportion of all I occurrences of that allele to the total number of copies of the chromosome in the population (nN). Despite being related, the genotype frequency and the allele frequency are separate and one can infer the other from the other.

Ugo [173]

The most distinctive feature of ape dentition, which clearly distinguishes apes from Old World monkeys, is a Y-5 molar pattern.

<h3>What is the Y-5 molar pattern?</h3>
  • This is a distinctive type of molar teeth pattern found in apes and hominoids.
  • In this, 5 cusps or raised surfaces are present on the grinding surface of teeth, roughly forming a Y- shape. Therefore, this is also known as Y-5 pattern.
  • Whereas Old world monkeys have only 4 cusps on their lower molars present in a bilophodont pattern.
  • A Y-5 molar is formed when the tooth is divided into different pieces which form the complete structure of the tooth.
  • In bilophodont pattern the tooth is divided into 2 symmetric sections.
  • The dental formula of apes is 2.1.2.3/2.1.2.3 i.e. 2 incisors, 1 canine, 2 premolars, 3 molars.

If more individuals are born with the advantageous trait in each generation, over time what do you predict will happen to the pe
aivan3 [116]

Answer:

The percentage (%) of the alleles that code for this trait in the population will increase, as more individuals are born with the trait.

Explanation:

The more individuals get born expressing the trait, the higher its frequency gets in the population. By generation, there are more individuals carrying the allele for the advantageous trait. These individuals reproduce and increase the probabilities of the progeny to inherit the mentioned allele. When this sequence keeps occurring in the population over many generations, the allele percentage will increase. On the other hand, the other allele or alleles will decrease. Probably, if there are no changes that might influence or affect this pattern, the alleles for the advantageous trait will fixate, while the other allele might get lost.

How many consumers are omnivores in the food web below?
lord [1]

Answer:

1

Explanation:

Omnivores are animals that eat both plants and animals. If you look at the bottom of the food web, you need to look for arrows that point towards an animal that also consumes other animals. The arrows indicate that the energy is being transferred from the plants to the omnivore. The Raccoon is the other organism that eats both a producer (blackberries) and other predators such as garter snakes and meadow voles.
