Answer: Selection occurs within generations; evolution occurs between generations. All four of Darwin's postulates are true for the medium ground finch population on Daphne Major. Darwin's theory therefore predicts a change in the composition of the population from one generation to the next. In biology, evolution is the change in the inherited traits of a population from generation to generation. ... Natural selection is a process that causes heritable traits that are helpful for survival and reproduction to become more common, and harmful traits to become more rare.
Explanation:
D because it makes more sense
hi! producers are the main source of energy for consumers because they turn sunlight into chemical energy. without producers, no ecosystem would be able to survive because consumers would no longer have energy needed to live. hope this helps!
Answer:
Explanation:
First-generation (F1) progeny only showed the dominant traits, but recessive traits reappeared in the self-pollinated second-generation (F2) plants in a 3:1 ratio of dominant to recessive traits. Mendel then crossed these pure-breeding lines of plants and recorded the traits of the hybrid progeny
Answer:
Cc
Explanation:
A cleft chin is an example of a trait that is controlled by genetics. A cleft chin is when there is a dimple in the chin which arises when the two sides of the jaw don’t completely fuse together. Famous people with cleft chins are Henry Cavill, John Travolta and Niall Horan.
A cleft chin is generally thought to be a dominant trait. That means, if an individual carries one copy of the cleft chin gene (heterozygous), then they will display the trait.
There are three options: an individual can be homozygous dominant (CC), homozygous recessive (cc) or heterozygous (Cc). A heterozygous person will always have 2 different alleles (for any trait, not just cleft chin). In this case, a heterozygous person will have a cleft chin, because it is dominant. Therefore, an heterozygous person with a cleft chin will be Cc
Remember, the letter doesn't matter - they could also be denoted as Bb, Qq, Rr, Ff. The letter is arbitrary.
