Answer:
Combined parenting leads to faster reproduction
Explanation:
Genetic diversity or variations in the physical appearance of organisms is caused by genetic or environmental factors. Reproduction brings about variation through gamete formation, fertilization and mutations.
During prophase 1 of meiosis, homologous chromosomes pair to form bivalents. The crossing over at the chiasmata results in new gene combination and variations.
Fertilization permits parental genes to be brought together. This causes variations in members of the same family.
Mutation is the spontaneous change in genetic make-up. These changes may be inherited by offspring bringing variations. However, combining parenting does not increase genetic diversity.
Answer:
False
Explanation:
Phylogenetic analysis is a means of establishing evolutionary relationships.
Synapomorphy is a shared ("syn") character that is different from the form found in an ancestor that distinguishes a clade (monophyletic group)from other organisms
The absence of a trait can be used as a synapomorphy in phylogenetic analysis. For example, the loss of a trait, such as the loss of legs in snakes, can be a valuable synapomorphy for a clade.
The mitochondria is where food is turned into energy using water and carbon dioxide
<span>Both somatic and germinal mutations are contributors of evolution. Somatic mutations occur within tissues of individuals that give the said individual differing traits and characteristics. Germinal mutations occur in reproductive cells that can be passed on to offspring, altering their traits and characteristics.</span>
