To protect the cells internal environment and balance the nutrients and proteins that keep the cell alive
The answer is B, because this is the only negative effect
Answer:
The field of genetic engineering has remained controversial ever since its existence. Some scientists extremely favour the recombinant DNA technology whereas others consider it to be dangerous.
Some of the positive impacts would be that these animals would provide better milk quality and quantity. The meat of these animals will be able to provide better nutrition. Hence, in this way these animals will help to fight malnutrition.
The negative impacts of such animals would be that one never knows that if a mutation occurs in these organism than how dangerous it could be for the world. There is also a threat that the genetically engineered animals if mated with the wild life can cause threats. It might also lead to the wild- life of animals being extinct.
Answer:
The options including the genotypes are not included. On a general note, three genotypes that are possible for this trait including their phenotype is:
WW- Wide wings
Ww- Wide wings
ww- thin wings
Explanation:
This question involves a single gene coding for wings width in a certain bird. The allele for wide wings (W) is dominant over the allele for thin wings (w). This means that allele 'W' will always mask the expression of allele 'w' in a heterozygous state.
There are three possible genotypes considering this trait.
WW- homozygous dominant genotype which wings will be phenotypically wide because it contains a combination of same dominant alleles.
Ww- heterozygous dominant genotype which wings will be phenotypically wide because I this combination of alleles, the W allele will always express itself phenotypically over allele 'w' considering the dominance of W.
ww- homozygous recessive genotype which wings will be phenotype thin because it contains a combination of same recessive alleles.
N.B: a recessive trait will only be expressed in a homozygous condition.
