in dogs, wire hair (S) is dominant to smooth (s). Cross of a homozygous wire-haired dog with a smooth-haired dog and show the ge
vesna_86 [32]
 You need to create a table like the one below and show that, if crossed, these two dogs would create 100% wire-haired dogs, but with smooth genotype. They will be heterozygous wire-haired, because the wire hair dominates over the smooth hair.

The genotype is the genes you can't see, and phenotype is what you can see. So some traits can just be in your genotype, so you don't have them but your children can get them. If there are two different traits in your genes the dominant ones will win and will be the ones you see. There needs to be two recessive genes for that gene to win. I hope this was clear. It's a little complicated!

When observing an ECG, you will see many different deflections from baseline known as waves. These deflections represent various
mote1985 [20]

Answer:

1. Ventricular depolarization −−QRS complex

2. Total time it takes for the ventricular muscle to depolarize and repolarize −−QT interval

3. Atrial depolarization −−P wave

4. Conduction through the atrioventricular (AV) node −−PR segment

5. Ventricular repolarization −−T wave

6. The ventricles are in their depolarized state −−ST segment

7. Conduction through the atrioventricular (AV) bundle −−Q wave

Explanation:

ECG or electrocardiogram is the graphical representation of the heart's rhythm and electrical activity measured by electrical signals. The contraction of the heart shows electrical activity.

There are various deflections shows from baseline and known as specific waves and there are also some flat lines between waves called intervals. This atrial depolarization is called P wave and ventricular repolarization called T wave and the time between ventricular muscles depolarization ( QRS complex) and repolarization is QT interval. Conduction through the atrioventricular (AV) bundle is known as Q wave.
