Answer:

Explanation:

If there are 5 genes, let us assume that they are in the alternative forms with 2 possible gets for each five... So we have

2 possible gametes for each five = 2 to the power of 5 = 32 gametes

Then genotypes = 3 to the power of 5 = 243

The same also for 10 genes

2 possible gametes for each 10 = 2 to the power of 10 = 1024 gametes

Then genotypes = 3 to the power of 10 = 59,049

The same also for 20 genes

2 possible gametes for each 20 = 2 to the power of 20= 1,048,576

Them genotypes = 3 to the power of 20 = 3,486,784,401

Briefly explain how x-rays, CT/CAT scans, ultrasounds, and MRI are used to diagnose diseases.
LUCKY_DIMON [66]

Answer:

These techniques include x-rays, computed tomography (CT) scans, and magnetic resonance imaging (MRI). These imaging tools let your doctor "see" inside your body to get a "picture" of your bones, organs, muscles, tendons, nerves, and cartilage. This is a way the doctor can determine if there are any abnormalities.

Explanation:

hope it helps :)

How does crossing over add to the genetic diversity of sexually reproducing organisms?
neonofarm [45]
<span>Crossover is the first way that genes are shuffled to give rise to genetic diversity. Crossover takes place in sexual reproduction. Chromosomes line up side by side and break off pieces of themselves, then trade those pieces with each other. When they break at the same place (locus) in the sequence of base pairs, the result is an exchange of genes called genetic recombination. That is the normal way for crossover to occur. Genetic recombination ensures that the daughter cells produced have a different genetic makeup from the parent cell and thus diversity is created.</span>
