The traits an organism displays are ultimately determined by the genes it inherited from its parents, in other words by its genotype. Animals have two copies of all their chromosomes, one from each parent.
Answer: Traits acquired during a lifetime are passed to offspring.
Mass extinctions. Dinosaurs is the most recent (?)
Answer:
Chromatin helps regulate DNA replication.
Explanation:
Chromatin helps condense DNA strands to smaller units that can be easily managed during DNA replication and gene expression. This also prevents the breakage of the strands and facilitates equal distribution of chromosomes during cell division (during mitosis and meiosis).
Answer:
Two true-breeding stocks of pea plants are crossed. One parent has red axial flowers and the other has white, terminal flowers; all F1 individuals have red, axial flowers. The genes for flower color and location assort independently.
Explanation:
If 1,000 F2 offspring resulted from the cross, approximately how many of them would you expect to have red, terminal flowers=190
Among the F2 offspring, what is the probability of plants with white axial flowers=3/16
