The genetics of a-thalassemia are similar to narrow sense heritability in that there is a gradation of phenotype, with each alle

le seeming to contribute equally to the trait. However, there are also differences from narrow sense heritability. In particular, as you can see from your answers above, it is difficult to predict offspring phenotype based only on parental phenotype. What two aspects of HBA1 and HBA2 combine to offset what would otherwise appear to be narrow sense heritability of a-thalassemia?

Answer:

In strict mode, the narrow-sense heritability is the proportion of the additive genetic variance that contributes to the total of the phenotypic variance. This value can be associated with the inheritance of the a-thalassemia .

Explanation:

A-thalassemia is a genetic disorder caused by mutations affecting four different genes that encode alpha-globin, thus affecting the hemoglobin production process and, consequently, oxygen transport. The mode of inheritance of the a-thalassemia may be associated with narrow sense heritability since the phenotype is manifested by gradation, i.e., each allele might contribute in similar mode to this genetic condition.

In a lever, 120 N load is attached at a distance of 20 cm from the fulcrum. If this effort is used to lift 50 kg weight then, th
ycow [4]

Answer:

The load distance is 4.9 cm

Explanation:

Given;

Effort applied to the lever, E = 120 N

Load overcame by the effort, L = 50 kg = 50 x 9.8 = 490 N

distance of the effort from the fulcrum, e = 20 cm

let the distance of the load from the fulcrum = d

The following simple set-up is used to illustrate this lever;

  -----------------------------Δ-------------------------------

 ↓          20cm                             d                   ↓

120 N                                                                490 N

Lever operates on the principle of moment, so take moment about the pivot (fulcrum);

490(d) = 120(20)

d = (120 x 20) / (490)

d = 4.9 cm

Therefore, the load distance is 4.9 cm

How do mutations increase variety
Rzqust [24]
Genetic mutations increase variety by adding uniqueness to the world. Genetic mutations can come in all shapes and sizes based on the chromosomes in cells. Perhaps someone was born with one blue eye and one green eye, or perhaps they have hair a certain, unusual color. Genetic mutations add variety to the world by making sure everyone isn't the same!!
