The number of cytosine in a DNA molecule equals the number of guanine.
The male fruit fly has an XY profile of the sex chromosomes, and the female has an XX profile of the sex chromosomes.
If a male is white-eyed, then it must have a white recessive allele on his only X chromosome and the red eyed female can be homozygous (having two dominant red eye alleles) or heterozygous (having both a dominant and a recessive allele).
If the female is homozygous then all of the offspring will be red-eyed, and if she's heterozygous then half of the offspring will be white eyed. (see the table provided below)
Answer:
0.50
Explanation:
According to the given information, the frequency of the hornless genotype in the population is = 16% = 0.16. This means that the frequency of the hornless allele in the population is = square root of 0.16 = 0.4.
The gene for the horns in unicorn has three alleles. If the frequency of the allele for twisted horns is represented by "p" and that of the hornless allele is represented as "q", then the frequency of the allele for the longhorn would be (r) = 1- (p+q).
This is due to the fact that the sum total of frequencies of all the possible alleles of a particular gene in a population in the Hardy Weinberg Equilibrium is always 1 (p+q+r =1). Now, putting the values of p and q in the formula to calculate the frequency of allele for the longhorn (r) = 1- (0.1 + 0.4) = 1-0.5 = 0.5
The correct answer here would be A: Space Station
