A population is made up of individuals where 77 have the A1A1 genotype, 65 have the A1A2 genotype, and 123 have the A2A2 genotyp

lana [24]

Answer:

Frequency of allele A1- 0.41

Explanation:

In Hardy weinberg equilibrium,

P refers to the dominant allele

q refers to the recessive allele

The allele frequency will be p+q=1

The genotypic frequency is- P²+q²+2pq=1

P²= genotype of dominant trait ( A1A1)- 77

2pq= genotype of heterozygotes (2pq)- 65

q²= genotype of recessive trait (A2A2)- 123

Total number of offsprings= 77+ 65+ 123

= 265

Now to calculate allele frequency of A1=

$\dfrac{\text{number of A1A1 offspring}}{ \text{total number of offspring}}+\dfrac{1}{2}(\dfrac{\text{number of A1A2 offspring}}{\text{total number of offspring}})$

= 77/265 + 1/2( 65//265)

= 0.290+ 0.122

= 0.413

Thus, 0.41 is correct.

What is an invasive species?

Serga [27]

Answer:

An invasive species is an organism that causes ecological or economic harm in a new environment where it is not native.

Explanation:

Invasive species can harm both the natural resources in an ecosystem as well as threaten human use of these resources. An invasive species can be introduced to a new area via the ballast water of oceangoing ships, intentional and accidental releases of aquaculture species, aquarium specimens or bait, and other means.

Invasive species are capable of causing extinctions of native plants and animals, reducing biodiversity, competing with native organisms for limited resources, and altering habitats. This can result in huge economic impacts and fundamental disruptions of coastal and Great Lakes ecosystems.

The way living things are organized can be represented on a chart. A portion of the organization chart is shown below: (1 point)

HACTEHA [7]

Answer:

The answer is Cells.

Explanation:

The chart is a basic molecular design of multicellular organisms.
Atoms, molecules, cells, tissues, organs, organ systems are the building blocks of the human body which combine together on the basis of similar function or structure to achieve various body functions.
Atoms form chemical bonds with other atoms and form molecules.
Molecules combine together to form cells.
Cells are the basic functional and structural units of life.
Cells that perform similar functions combine together to form tissues.
Two or more kinds of tissues that perform similar functions combine to form organs.
Organs, in turn, form organ systems such as the respiratory or cardiovascular systems etc.
