Answer:
There are no options to this question, however, the question can be answered. The answer is:
FF and FF/Ff
Explanation:
This question involves a single gene coding for possession or not of freckles in humans. The allele for freckles (F) is dominant over the allele for no freckles (f). This means that genotypes FF and Ff (heterozygous) will possess freckles while only genotype ff will not.
According to this question, a couple has several children in which all of the children have freckles i.e. have either genotype FF or Ff. This is as a result of the fact that the parent's genotypes were either FF or Ff. That is, one parent is FF while the other is either FF or Ff. This genotypes will only produce children with freckles.
Answer:There may be many possible alleles for any gene, but a diploid cell or animal contains only two alleles of each gene or two copies of a single allele; a haploid gamete contains one copy of each gene, so only one allele.
Explanation:
Well a mutation is like a change in the DNA and so if there was a mutation in the antártica fish, something in their genes would change. If that mutation has a positive effect on it, then that mutation would be passed down to the generations of fish, helping that fish with its survival or something
Answer:
The dependent variable changes in response to the independent variable.
Explanation:
Think of it like cause (independant) and effect (dependant).
