Answer:
the phase that describes a plant spore but not the plant seed is called meiosis
I'm pretty sure its A- true.
Hope this helped. Have a good day! :D
Answer: Dominant allele codes for a functional protein. Recessive allele codes for a less functional or nonfunctional protein, or it does not code for any protein.
Explanation:
Alleles are different forms of a gene. There are two types, dominant and recessive allele. Heterozygous organisms have one of each, and the dominant allele is expressed. Homozygous organisms have either two dominant alleles or two recessive alleles.
<u>A dominant allele produces a functional protein</u>, even in the presence of a recessive allele, because only one copy of the allele is enough and it masks the effects of the recessive allele. This dominant trait is shown in individuals who are homozygous dominant or heterozygous,
<u>A recessive allele produces a less functional or nonfunctional protein, or it does not code for any protein at all.</u> A recessive allele does not become a trait unless both copies of the gene are present.
Genetic mutations are the alterations of genetic materials. <u>Fatal familial insomnia</u> is a disorder, caused by a genetic mutation, involving a progressive inability to sleep.
<h3>What is fatal familial insomnia?</h3>
Fatal familial insomnia is a brain disorder that can be inherited and affects the sleep cycle. It is a neurodegenerative disease that leads to mental and physical deterioration because of a lack of sleep.
FFI is caused by a genetic mutation in the PRNP gene that alters the mechanism of the thalamus resulting in an alteration of the sleep activity that leads to exhaustion.
Therefore, <u>fatal familial insomnia</u> is the correct blank.
