The most important cause of the age-related drop in female fertility is

RideAnS [48]

Actually some of the important causes for the age related drop in female fertility is due to some chronic bad habits like chain smoking, regular alcohol intake and taking big dose of drugs, and also due to wrong diet or junky bad food habits, then mainly its due to hormone imbalance problems.

Answer:

The earth is made up of three different layers: the crust, the mantle and the core. This is the outside layer of the earth and is made of solid rock, mostly basalt and granite. There are two types of crust; oceanic and continental. Oceanic crust is denser and thinner and mainly composed of basalt. The inner core is made from Iron and Nickel.

A genetically heterogeneous population of rice has a mean in the number of days to maturation of 30. Selection for decreased per

chubhunter [2.5K]

Answer:

h² = 0.6

Explanation:

Before answering the question, we need to know a few concepts.

Artificial selection is the selecting practice of a specific group of organisms in a population -that carry the traits of interest- to be the parents of the following generations.

Parental individuals carrying phenotypic values of interest are selected from the whole population. These parents interbreed, and a new generation is produced.

The selection differential, SD, is the difference between the mean value of the trait in the population (X₀) and the mean value of the parents, (Xs). So,

SD = X₀ - Xs

Heritability in the strict sense, h², is the genetic component measure to which additive genetic variance contributes. 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 = X₀ - X₁

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

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

Available data:

You are selecting rice´s decreased period of maturation.
The population of rice has a mean maturation time of 30 days → X₀
Parental selected average period to maturation is 25 days → Xs
F1 plants mature on average in 27 days → X₁
N arrow sense Heritability → h²

According to what we sow previously, we need to find out the value of h².

We know that h² = R/SD, so we need to get R and SD first.

R = X₁ - X₀

R = 27 - 30

R = -3

SD = Xs - X₀

SD = 25 - 30

SD = -5

Knowing this, we can calculate h²

h² = R/SD

h² = -3/-5

h² = 0.6

Which type of organism is characterized by having jointed appendages, ability to molt, and three sets of fused segments? echinod

mel-nik [20]

The members of the phylum arthropoda have jointed legs. the number of jointed legs are variable, may be three pairs as in cockroaches, four pairs in prawns and even hundred pairs in centipedes. Members of this phylum have ability to shed their their exoskeleton(molting) and body is divided into three fused segments - head, thorax and abdomen.
