Congenital analgesia is a rare autosomal recessive trait. What is the likelihood that the first two offspring of a cross between

telo118 [61]

The likelihood that the first two offspring of the cross will have congenital analgesia would be 1/16

<h2>Autosomal Recessive Traits</h2>

For autosomal recessive traits, two recessive alleles are needed for the trait to manifest while one recessive allele means heterozygosity.

In this case, let us assume that congenital analgesia is represented by the allele b; heterozygous individuals will, thus, be Bb.

Bb x Bb

BB Bb Bb bb

Probability of producing unaffected offspring = 3/4

Probability of producing affected offspring = 1/4

Likelihood of the first two offspring having congenital analgesia = probability of first having congenital analgesia and the second having congenital analgesia

= 1/4 x 1/4

= 1/16

Lubov Fominskaja [6]

Some skeletal traits that define modern homo sapiens are a small face, high rounded skull, small jaws, bony chin , vertical and high forehead, a narrow nasal aperture, narrow upper body and long legs is known as mental eminence.

<h3>What are skeletal traits?</h3>

The morphological diversity of the domestic dog serves as an example of how mammalian skeletal traits may evolve quickly and undergo significant modifications.
Here, we employ principal component analysis to identify systems of features characterizing skeletal traits in a population of Portuguese Water Dogs.
Through this research, phenotypic variation is divided into separate parts that can be utilized to analyze the genetic networks controlling intricate skeletal traits.
We demonstrate that unlinked quantitative trait loci associated with these major components separately support both inverse correlations between structures and correlations within skeletal traits (for example, within the skull or among the bones of the limbs) (e.g., skull vs. limb bones).

A population of wolves predates a population of moose on Isle Royale, Michigan, where there are fewer wolves than moose to start

andrew11 [14]

Complete question:

A population of wolves predates a population of moose on Isle Royale, Michigan, where there are fewer wolves than moose to start. The wolves prey on the moose and eat well, allowing them to have abundant offspring. However, as the wolf population rises, the moose population drops, and over time, the wolf population begins to drop also because of the reduced availability of resources. As the wolf population drops, moose are able to better survive and reproduce, causing the moose population to rise. With this abundance of moose, the wolf population is able to rebound until their population exceeds the moose population’s ability to support the number of wolves. Which population dynamic does this series of oscillations represent?

Delayed density dependence
Delayed density independence
Extinction vortex
Carrying capacity

Answer:

Delayed density dependence

Explanation:

The Delayed density dependence occurs when two species are in interaction (prey-predator or parasite-host), and the dynamic of each population follows the dynamic of the other population. The natality and mortality rates of one species follow the rates of the other species.

<em>Delayed density dependence dynamics regulate populations and allow the occurrence of equilibrium or balance in nature.</em>

<u>Predator-prey scenarios</u>

Assuming that the prey lives in the ideal environment with no predators, it shows an exponential growth rate. Prey can grow, develop, and reproduce, increasing its population size. The more available items, the more predator there will be. The predator population increase in size, and its presence affects the prey populations, leading it to decrease. So there are fewer available items to prey on.

The prey population also affects the predator population. After the increase in the predator population size, the number of available prey decreases. The predator lives in an ideal environment but depends on the prey density. The more predators there are, the fewer prey there will be left. The predator population decreases exponentially due to the item's lack. The predation rate depends on density as well as natality and mortality rates.

So, to sum up,

prey population increases in size
predator population increases in size
prey population decreases in size
predator population decreases in size

In this particular example, the wolves population follows the moose population and vice-versa. It is not simultaneous. It happens with a delay.

<em>Moose influences the wolf population because they are their source of food. The more moose, the more wolves there are. The fewer moose, the fewer wolves there are. </em>

This is a density-dependent dynamic because both populations are affected when they reach a high value.
