Assume that a mutation occurs in the gene responsible for the production of hexosaminidase a, such that only about 50% of the en

zyme activity is found in the heterozygote compared with a homozygous normal individual. if heterozygotes are phenotypically normal, we would say that the mutant allele is recessive to its normal allele.

This statement is true.

In the case of autosomal dominant disease, the person is either homozygous (which is very rare) or heterozygous. On the molecular level, either the mutation produced a new deleterious protein for the organism, or the mutation affected an existing protein in the physiological state and that a 50% activity is not enough to compensate for the needs. of the body.

In case of autosomal recessive disease, the sick person is always homozygous. If the two loci each have a different mutant allele, it is called a "composite heterozygote". People with autosomal recessive inheritance disorder have "mandatory heterozygote" parents.

What will the percentage of cytosine be in this segment of DNA?
Andrew [12]

Answer:

15%

Together, adenine and thymine compose 70% of the segment. This means that 30% of the section is composed of guanine-cytosine pairs. Since these two bases will be equal in quantity, 15% of the DNA section will be cytosine bases.

How many mitochondria does an average human muscle contain?
Novay_Z [31]

The chondrioma of a cell is the set of 300 to 800 mitochondria (from 1000 to 3000 in muscle cells, 2500 of which in a parenchymal cell of the liver or, which is a smooth muscle) which constitute up to 25% of the cell mass.

Very numerous in young cells and / or very active, which require a lot of energy (like spermatozoa), mitochondria are organelles because they constitute functional units of the cell: they are the "energy factories". Omnipresent in any animal or plant cell, mitochondria exist even in anucleate blood thrombocytes.

In horses, black coat (b) is dominant over brown coat (b), and being a trotter (t) is dominant over being a pacer (t). a black h
Tomtit [17]
In order for a recessive trait to be apparent in an organism, the organism must receive a copy of the allele for that trait from both parents. 
Let the:
black coat: B
brown coat: b
Trotter: T
pacer: t

The offspring received both of the recessive alleles because it demonstrates the recessive phenotypes. Therefore, they genotype of the offspring is:
bbtt

The black horse that is a pacer that can produce this offspring will be:
Bbtt

Therefore, the brown horse's genotype must be:
bbTt

The offspring will receive b from both parents and t from both parents.

In this case, the management of natural resources positively affects the human population, which might be to detriment of biodiversity.

<h3>What are natural resources?</h3>

Natural resources are any type of resources that can be obtained from nature (e.g., wood from trees).

Natural resources can not be indefinitely extracted from nature because it supposes a loss of biodiversity.

In conclusion, in this case, the management of natural resources positively affects the human population, which might be to detriment of biodiversity.
