Can parents with only recessive alleles give their child a dominant trait?

1 answer:

5 0

Answer: Kids inherit traits from their parents. Sometimes when two parents with different traits have kids, all the kids end up with only one parent's trait even though the children inherited both. In this case, one trait is said to be dominant over the other recessive one... This situation is called incomplete dominance.

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 statement best describes the relationship between the products of photosynthesis and the reactants in cellular respiration

zalisa [80]

The products of photosynthesis is to gain energy and build compounds, like glucose from carbon dioxide, making it anabolic

The reactants of cellular respiration are catabolic, and that refers to the breaking down of compounds, which releases energy.
