The probability that a group of four siblings includes all XY is 1/16 (6.5%), while the probability all XX offspring is 1/16 (6.5%). It is a simple genetic probability calculation.
<h3>Genetic probabilities and chromosomes</h3>
Females inherit two chromosomes X, whereas males inherit one chromosome X and one chromosome Y.
The probabilities of inherent two chromosomes X (females) are 1/2 (50%), while the probabilities of inherent one chromosome X and one chromosome Y (males) are also 1/2.
In consequence, the probability that a group of four siblings includes all XY is 1/16 (because it is equal to 1/2 x 1/2 x 1/2 x 1/2 = 1/16), the same for the probability all XX offspring (1/16).

Answer:
law of independent assortment
Explanation:
Independent assortment is the random distribution of the pairs of genes on different chromosomes to the gametes. I hope this helps :)
As the cells run out of oxygen they switch to anaerobic respiration, which allows the cell to make small amounts of ATP in the absence of oxygen; when the weightlifter’s muscle cells are not able to take in enough oxygen to make very much ATP, as he competes in the event.
Explanation:
Anaerobic respiration takes place when there is too low or no oxygen to perform aerobic respiration. This transfers the energy to the cells from glucose. It produces energy very quickly along with lactic acid and other waste products.
Anaerobic respiration is highly useful when short bursts of energy are required very quickly to energize the muscles to perform high intensity activities like wrestling, weightlifting, intense short workouts, etc.
Lactic acid fermentation causes the muscles to burn out when high intense short burst physical activities are performed.
This would be considered a frame shift mutaion. Mutations can cause proteins to be incorrect strands, making diseasses
We can tell the age of a yeast cell by counting scars or bud scars.
As a mother cell of yeast goes through successive rounds of cell division, the Bud scars remain permanently deposited on the surface of the mother cell. The budding of each daughter cell leaves a ring-shaped deposit which is called a bud scar which deposits on the cell wall of the mother cell.
Therefore, if the mother cell divides, it will leave bud scars. Again if the daughter cell divides, then again, it will leave bud scars. So, counting these ring-shaped deposits or bud scars will give the number of successive cell divisions and the age of yeast cells.
