In a population of cattle, the average body fat percentage is 10.5%. You select parents with an average body weight percentage of 20.8%. The offspring they produce have an average body weight percentage of 17.6%. Based on these data, what is the narrow-sense heritability of this trait

Answers

Answer 1

Heritability in the narrow sense -h²- refers to the proportion of the phenotypic variability that is influenced by genetic factors. In the exposed example, the narrow-sense heritability of this trait is h² = 0.689 ≅ 0.7

-----------------------------

Before answering the question, let us first review a few concepts.

The selection differential, SD, is calculated by getting the difference between the mean value of the desired trait in the population (X₀) and the mean value of the same trait expressed by parents, (Xs). So,

                                                     SD =  Xs - X₀

Heritability in the narrow sense -h²- is the measure of the genetic component to which additive genetic variance contributes.  

It referes to the proportion of the phenotypic variability that is influenced by genetic factors.

The heritability might be used to determine how the population will respond to the selection done, R.  

                                                        h² = R/SD

The response to selection (R) refers to the metric value gained from the cross between the selected parents. R can be calculated by multiplying the heritability h² with the selection differential, SD.  

                                                          R = h²SD  

R also equals the difference between the new generation phenotypic value (X₁) and the original population phenotypic value (X₀),  

                                                          R = X₁ - X₀

Now that we know these concepts and how to calculate them, we can solve the proposed problem.

Available data:

Population average body fat ⇒ 10.5% ⇒ X₀  Selected parents average body weight ⇒ 20.8% ⇒ XsOffspring average body weight ⇒ 17.6% ⇒ X₁

We ned to get the narrow-sense heritability of this trait, h².

h² = R/SD

R  = X₁ - X₀ = 17.6% - 10.5% = 7.1%SD = Xs - X₀ = 20.8% - 10.5% = 10.3%

     

h² = R/SD =  7.1%  /   10.3% = 0.689 ≅ 0.7

The narrow-sense heritability of this trait is h² = 0.689 ≅ 0.7

Answers

Pollen is released from the anther and is transferred to the stigma. It's the 3 rd answer that is correct

The correct answer is pollen is released from the anther and is transferred to the stigma. A pollen tube forms and grows through the style. The pollen tube reaches an ovule within the ovary where the sperm fertilizes the egg.

This option correctly defines the interaction that occurs between a plant's reproductive parts during self-fertilization as it explains the pollination process and fertilization, when pollen grains are released then are transferred to the stigma the pollen tube is there that reaches ovule and the sperms fertilize an egg.

What is pollination?

Transfer of pollen from anther to the stigma of plants. Pollen is released from the anther and is transferred to the stigma. A pollen tube forms and grows through the style. The pollen tube reaches an ovule within the ovary where the sperm fertilizes the egg.

What is an invasive species?

An invasive species is a category of non-native species that has overtaken the habitat to which it was initially introduced.

Native plants and animals may go extinct as a result of invasive species, which can also decrease biodiversity, compete with native species for scarce resources, and disrupt habitats.

Preventative measures are the most practical and secure method of managing invasive species. It is far more effective to deal with invasive species early on and quickly than to try and contain an extensive infestation. The invasive species may be the target of control and management measures if eradication is not achievable.

Could there be winds without differential heating? Using evidence from Unit 5 explain what differential heating is and whether this effects the earth’s global wind patterns.
HELPPP PLEASE SITE EVIDENCE (WILL MARK BRAINLIEST)!!!!!!!!

Answers

Differential heating is responsible for the wind patterns across the globe.

Differential heating is defined as the difference in heating of air on the land versus water. Sea breezes occur when land heats up faster than water which rises and creates a low pressure system. The high pressure air from the sea influxes is responsible for the creation of a sea breeze.

Unequal heating of the Earth's surface is responsible for the formation of large global wind patterns. Warm air rises at the equator and moves toward the poles while on the other hand, the cooler air rises at the poles and moves back toward the equator so in this way the earth’s global wind patterns occurs so we can say that differential heating is responsible for the wind patterns across the globe.

The cell enters the G2 phase following DNA replication, which takes place during the S phase. In order to manufacture the elements required for cell division, the cell continues to expand and goes through further protein synthesis during this phase. These proteins play a role in the development of the mitotic spindle, control of cell cycle checkpoints, and cytoskeleton organisation.

The cell also creates organelles like the mitochondria and endoplasmic reticulum to make sure there will be enough energy and cellular building blocks for the impending division in the phase.

The trait must have no other advantage in fitness

The trait must be for the good of the species

The trait must be heritable

The trait must advance the goal of evolution

Answers

Answer:

For natural selection to occur, it is true that there must be genetic variation in the population.

Explanation:

According to evolution, natural selection implies the changes that occur in the genotype of a species, due to the effect of environmental factors, and which guarantee its survival through adaptive evolution.

For natural selection to occur, three fundamental conditions must exist:

A trait that can be inherited from one generation to another.

The trait is subject to variability between subjects of the same species.

Genetic variability can determine the possibility of reproductive success and survival.

Therefore, a necessary factor for natural selection to occur is that genetic variability exists in the population.

For natural selection to occur :-

There must be variation in traits in the population.The trait must cause the individual to evolve.The trait must be for the good of the species.The trait must be heritable.The trait must advance the goal of evolution.
