Answer:
Meiosis
Explanation:
Because that's when alleles of different genes cross over, specifically in Prophase I.
Mendel's law of Dominance is demonstrated by these families.
Explanation:
Mendel's Law of Dominance states that the recessive gene will not be expressed in front of Dominant gene. He found that in a heterozygous gene the allele for Dominant trait will mask the trait expressed by recessive trait, also one trait will overshadow the other trait both the traits will not appear in offspring.
Aa X Aa (In first family both parents are heterozygous)
AA X aa ( In second family the father is dominant and mother is recessive and albino, but no child will be albino since all would be heterozygous for the trait.)
I looked this question up for you and this is what I found I hope it's helpful for you
I believe it would be to calculate the amount of C-14 atoms left. scientists began to find out how long an object has been decaying, this has to do with half lifes etc. and how long a specific mineral/elements half life is. they use this to calculate how old it is (not an exact age but it's very accurate.)
