Answer:
0.42
Explanation:
Since 70% of the gametes have an A1 allele, this means that the frequency of the A1 allele in the population is 70% or 0.7.
The population is in Hardy-Weinberg equilibrium. For this population, the frequency of another allele for the same locus (A2) would be= 1- frequency of A1 allele = 1-0.7 = 0.3
The proportion of flies carrying both A1 and A2 alleles would be = 2 x frequency of A1 allele x frequency of A2 allele.
So, frequency of heterozygous flies= 2 x 0.7 x 0.3 = 0.42 or 42%
Answer:B
Explanation:
An octopus only reproduces one time, but penguins may reproduce between 4 and 12 times in their lives.
C.
Baby penguins are left to fend for themselves from the time they hatch, so they quickly become self-sufficient.
D.
The success of a species depends on the number of offspring that survive long enough to reproduce.
Humans affect biodiversity by their population numbers, use of land, and their lifestyles, causing damage to habitats for species. ... Through proper education, and by demanding that governments make decisions to preserve biodiversity, the human population will be able to sustain life on earth longer.
