How many recessive alleles I need for an expression of a recessive phenotype

Biology

Arisa [49]3 years ago
7 0
You need two recessive alleles (xx). If even one dominant allele is present, the dominant trait will show (Xx or XX will both result in the dominant trait showing). That’s why they’re called dominant traits, because they overpower the recessive traits. In order for a recessive trait to show you must have two recessive alleles.

tatyana61 [14]

The Earth core has two layers: the outer core, and the inner core. Moreover, the magnetic field protects Earth from solar weather.

The Earth's magnetic field is an invisible layer that protects life from the majority of the solar wind blast.

The magnetic field covers us from charged solar particles that crash into it and then flow around it.

Moreover, the Earth core has two layers: the outer core and the inner core, which are separated by a boundary known as the Bullen discontinuity.

<h2>Mutation & genetic drift</h2>

Explanation:

  • A mutation is characterized as a lasting change to the DNA succession in a quality. This change moves the hereditary message conveyed by the quality and can modify the amino corrosive arrangement of the protein the quality encodes. This implies future cells created by the quality will just convey a specific characteristic.  
  • Genetic Drift is the change in the hereditary structure of a populace after some time because of possibility or irregular occasions. In instances of hereditary float, for example, catastrophic events or periods of irregular climate, the age that makes due to repeat won't really be the fittest, yet the most fortunate. Hereditary float doesn't allude to a particular change in hereditary cells, rather to arbitrary events that impact a population's genetic makeup.
  • Hence, the right answer of the fill up the blank is "mutation and genetic drift".
