Answer:
Little gene flow with surrounding populations
Explanation:
Hardy-Weinberg equation is simply used to in describing the principle of population genetics. It was invented in 1908 by G H Hardy and Wilhelm Weinberg.
It further be explained as the mathematical equation used in calculating the genetic variation of a population.
The equation is represented as p2 +2pq +q2 = 1
where, p2 = dominant, 2pq = heterozygous, q2 = homozygous.
It should be noted, the condition that that will make the equation accurate in this aspect is little gene flow with surrounding population.
Answer:
There are no chances for this couple to have a child with Tay-Sachs disease. 0% of the possibilities.
Explanation:
Tay-Sachs disease affects the nervous system and is potentially mortal. It is transmitted from parents to progeny. Tay-Sachs is caused by a defective gene in the 15 chromosome.
The child that recesives two coppies of this defective gene, one from the mother and one from the father, results sick. <u>But if only one of the parents transmits the gene, then the child will be a carrier.</u> This child won't be sick but will transmit the gene to his/her own progeny.
<u>Available data</u>:
- The allele for tay-sachs is a recessive allele, "t"
- Tim McGraw to determine is a carrier, Tt
- Tim´s wife is not a carrier, TT
<u>Cross:</u>
Parental) TT x Tt
Gametes) T T T t
Punnet square) T T
T TT TT
t Tt Tt
F1) Progeny genotype: 2/4= 1/2 normal, TT
2/4= 1/2 Carrier, Tt
0/4= 0 Sick, tt
What are the chances they could have a child with Tay-Sachs?
There are 0% of the possibilities that this family will get a sick child.
<span>Answer:
Turning from side to side will change the position of the catheter, thereby freeing the drainage holes of the tubing, which may be obstructed. Drinking a glass of water and deep breathing and coughing do not influence drainage of dialysate from the peritoneal cavity. The position of the catheter should be changed only by the primary healthcare provider.</span>
