Mention two advantages of the extensive network of endoplasmic reticulum

nikklg [1K]

Answer:

Following are the two advantages of endoplasmic reticulum.

1) Endoplasmic reticulum is an organelle of the cell which is responsible for the production of protein for the cell. This protein is sent to the Golgi apparatus where it is modified and used by the cell where it is needed.

2) Endoplasmic reticulum also helps in the removal of toxic substances from the cell. If these toxic substances are not removed, it causes damage to the cell.

You are an almond grower and want to determine whether almond size (measured as shelled almond weight) is a heritable trait. A s

inn [45]

Answer: 1. S = 0.77

2. R = 0.14

Explanation:

1. Selection differential is the difference between the population mean and the average of the selected parents. Its symbol is S.

S = mean of selected parents - population mean

S = 6.48 - 5.71

S = 0.77

2. Response to Selection is how much gain you make when crossing over selected parents. Its symbol is R.

R = mean of offspring of selected parents - population mean

R = 5.85 - 5.71

R = 0.14

3. Heritability is, basically, a statistical variable that shows how much the variation in a trait is due to genetic factors. Its symbol is h².

To calculate it, use Breeder's Equation:

R = h²S

$h^{2}=\frac{R}{S}$

$h^{2}=\frac{0.14}{0.77}$

h² = 0.18

4. You would expect the production to be strongly influenced by environment, because heritability lies between 0 and 1. Low heritability means there is low level of resemblance between offspring and parents. As this program heritability is low, the resemblance is small, which means the characteristics are influenced mostly by the enviroment.

What blood types are possible for a child whose parents both have AB blood type?

erma4kov [3.2K]

Answer:

-blood type a

-blood type b

-SOMETIMES type o but very rarely.

Explanation:

Each biological parent donates one of their two ABO alleles to their child. A mother who is blood type O can only pass an O allele to her son or daughter. A father who is blood type AB could pass either an A or a B allele to his son or daughter. While a child could have the same blood type as one of his/her parents, it doesn't always happen that way. For example, parents with AB and O blood types can either have children with blood type A or blood type B.
