Answer:
Genetic drift
Explanation:
Genetic drift is an evolutionary mechanism that in a population it changes allelic frequencies over generations just by chance. For this reason, small populations are more susceptible to be affected by genetic drift than bigger populations.
In this example, Indiana Jones visited a small village of 50 people and over generations allele A probably was lost just by chance, or by genetic drift.
Answer;
0.39 times the mass of Venus
The mass of Jupiter is 0.39 times the mass of Venus
Explanation;
Important facts;
-Jupiter is 11.8 times bigger than Venus.
-Almost 1400 planets the size of Venus could fit inside Jupiter.
-Venus is the second closest planet to orbit the Sun
The mass of Venus is 4.87 × 1024 kilograms
The mass of Jupiter is 1,898 × 1024 kilograms
Hence; The mass of Venus/ The mass of Jupiter
4.87 × 1024 kilograms/1,898 × 1024 kilograms
= 0.39
Therefore; The mass of Jupiter is 0.39 times the mass of Venus
If a fragment of a
chromosome breaks off and then reattaches to the original chromosome at the
same place but in the reverse direction, what happens would result to
inversion.
I hope I was able to answer your question. Have a good day.
Answer:
Genetic relationships are analysed based on the comparison of allelic identity or differences, regardless of the number of SNPs that differ between two alleles of a gene, which simplifies the analysis.
