Answer and Explanation:

The cells of the runner respire through anaerobic respiration due to inadequate oxygen leading to formation of lactic acid. Under these conditions lactic acid accumulates in the muscles which might cause fatigue and result in muscle soreness and cramps. Lack of enough oxygen makes the cells to respire anaerobically altering cell respiration.

In a population of tomato plants mean fruit weight is 60 g and narrow-sense heritability (or realized heritability - h2) is 0.3.

Alla [95]

Answer:

The mean weight of the progeny is $66$ grams

Explanation:

Given -

Mean fruit weight of tomato plant (M1) $= 60$ g

Narrow sense heritability (h2) $= 0.3$ g

Mean weight of tomato plant selected for artificial selection (M0) $= 80$ g

$h_2 = \frac{M_2 - M_1}{M_0 - M_1}$

Substituting the given values in above equation, we get -

$0.3 = \frac{M_2 - 60}{80 -60} \\0.3 = \frac{M_2 -60}{20} \\6 = M_2 -60\\M_2 = 6 + 60\\M_2 = 66$

The mean weight of the progeny is $66$ grams
