What is crossing over?When chromosomes of the same type are paired together during meiosis, a biological event called crossing over takes place. Parts of the chromosome can be exchanged when two chromosomes, one from the mother and one from the father, line up.
The same genes may be present on the two chromosomes in different versions. The genetic material in the germ line can switch places, a process is known as crossing over.
Pairs of chromosomes from each parent align to allow similar DNA sequences from the paired chromosomes to cross over one another during the development of egg and sperm cells, commonly known as meiosis.
Therefore, the percentage that will be speckled is 20%.

Speciation, which leads to diversity among species through natural
selection, occurs when
Once similar species are no longer able to mate and produce fertile
offspring
Organisms develop characteristics that mimic traits of a completely
different species.
Species experience change within their lineage and develop new
characteristics.
Species interact with other species in an ecosystem and develop
similar traits to each other.
Answer:
Natural selection and speciation: 'Ecological speciation'. ... Natural selection is generally recognized as a central mechanism of evolutionary change within species. Thus, natural selection plays a major role in generating the array of phenotypic and genetic diversity observed in nature.
Which of the following would likely move through the phospholipids of the
cell membrane most easily? *
CO2
Glucose
K+
Starch
Answer:
CO2
Explanation:
Oxygen and CO2 can move through the cell membrane through simple diffusion because they are small molecules.
It's possible that CO2 travels through the lipid bilayer far more quickly than any other molecule. Therefore, option (A) is correct.
What is the structure of cell membrane ?According to the fluid mosaic model, the plasma membrane is a mosaic of components—primarily, phospholipids, cholesterol, and proteins—that move freely and fluidly in the plane of the membrane.
All cells have a cell membrane, also known as a plasma membrane, which separates the interior of the cell from the external environment. A semipermeable lipid bilayer makes up the cell membrane. The movement of materials into and out of the cell is controlled by the cell membrane.
Therefore, small and simple molecules like water, H2O , CO2 can pass through the cell membrane easily as it is partially permeable.
