A cell with mutated dna may not be able to produce proteins accurately. what can lead to mutations in the dna?

1 answer:

8 0

These changes can be caused by environmental factors such as ultraviolet radiation from the sun, orcan occur if an error is made as DNA copies itself during cell division. Acquired mutations in somatic cells (cells other than sperm and egg cells) cannot be passed to the next generation.

Answer:

Option:Symbiosis in which both organisms benefit ecological niche.

Explanation:

Symbiotic association between any living organism:

The symbiotic association is the connection between any organisms, which are either benefited by each other or the relationship can be very negative for the either one, or it may be neutral in nature for both the organisms living inside a symbiotic relationship.

The symbiotic association between the different organisms are of four different natures or levels,which are as follows:

Mutualism: Inside the relationship or connection between any number of organisms in which there is mutual benefit for both the organisms, is called as the mutualism. For example, the insecticides living in the plants roots or any part of its body.
Parasitism:Such a symbiotic relationship is which between any two living organism either one of them is benefited while the other one is harmed by its effect. For example, the tape worms in the living body.
Predation: It is more simple to understand as the prey is hunted down and killed in order to fulfill the needs of the predator.For example the lion and the impala.
Commensalism: The type of association between the living organism in which one of the organism is benefited, while other is neither benefited nor harmed. For example the marine life on the back of the crab's body.

In some chickens, the gene for feather color is controlled by codominance. The allele for black is B and the allele for white is

Agata [3.3K]

Answer:

The question is incomplete, it lacks the main questions, those questions are:

a. What is the genotype for black chickens?

b. What is the genotype for white chickens?

c. What is the genotype for erminette chickens?

Explanation:

This question involves a gene coding for feather colour in some birds, in which the black allele (B) and white allele (W) is involved. According to the question, the gene coding for feather colour exhibits co-dominance i.e. both the black (B) and white (W) allele are expressed in a heterozygous state (BW) to form an erminette phenotype.

Hence, if the neither alleles is dominant or recessive over the other. The black phenotype will only be expressed when the genotype is BB.

The white phenotype will only be expressed when the genotype is WW

The combination of both alleles which results in the simultaneous expression of both in the erminette phenotype, will be BW genotype.
