She provided important evidence for the presence of JUMPING GENES.
She challenged existing concepts of what genes were capable of when she discovered that some genes could be mobile.
Answer:
The correct answer is 35 percent.
Explanation:
Allele D produced tiny ears, and allele d produces normal ones. If a heterozygous male with Dd mates with the homozygous female with dd, then generally, the expected offspring produced will be 50 percent with tiny ears, and 50 percent with normal ears.
However, in the given case, the penetrance is 70 percent. Thus, the probability of the offspring with tiny ears will be:
Penetrance = 70 %
Probability = 70 % of 50 % of 100
= 70/100 * 50/100 * 100
= 35 %
Hence, the probability of the offspring with tiny ears is 35%.
Things like fungus and bacteria there is no set trophic level for them and their niche is to break down dead plants and animals or even waste ( poop)
