Pretty sure its false, will get back to you c:
Answer:
Perfectly in theory, except there is chance involved
Explanation:
The Punnet square is a diagram that allows scientists to predict the possible outcomes of the offspring when the genotypes of the parents are known. This is in line with Mendel's principles, and from a theoretical point of view would match up perfectly. However, it all works based on <em>probability</em>.
However, inheritance is always down to chance. Of your parents 2 alleles, you always have 50:50 chance of inheriting one of the allele. Overall, this is what is predicted in punnet squares.
However, think about flipping a coin. There is always 50:50 chance of getting heads, but that doesn't mean it is impossible to flip a coin and get tails 10 x in a row. It is just less likely. So in reality, observations might deviate from the theory.
Answer:
D. the eggs are only viable for fertilization
Answer:
wouldnt that lead to a variation of the trait?
Explanation:
DNA is a double helix. It is composed of sugar, phosphates, and four different bases: A, T, G, and C. As cells grow, DNA is uncoiled and used to make proteins, but sometimes DNA is different between two bees (or humans) and then different proteins are made. These changes in the order of the A, T, G, C bases can be mutations or natural variations.
Substitution: This is usually just one base that has changed in the sequence.
Addition (insertion): One (or more) base added to the sequence. The surrounding sequence is the same after the insertion ends.
Deletion: One (or more) base is removed. The surrounding sequence is the same after the deletion.
