Answer:
If a plant's leaves only contained the vascular tissue xylem, then it will not be possible for the plant to absorb carbon dioxide. As carbon dioxide is required for photosynthesis to occur, this means that the process of photosynthesis will not take place. As a result, the plant will not be able to produce food as photosynthesis is the process by which plants make food. This will result in the plant to die eventually in the end due to lack of food.
Answer:
1. Cytogenetic mapping.
2. Linkage mapping.
3. Physical mapping.
Explanation:
1.<u> Cytogenetic mapping - Gene localization using microscope.</u>
A cytogenetic mapping is defined as the visual appearance of genes when seen by using microscope. The genes are stained and seeing under microscope that shows visually distinct regions, called dark and light bands and provide unique appearance to the genes.
2. <u>Linkage mapping - recombination distance s measured using genetic crosses.
</u>
Linkage mapping is done using linkage analysis by observing the genes linked to the offspring. It do not show physical distances but only shows genetic distances and how the two genes inherited together.
3. <u>Physical mapping - Determine nucleotide sequence distance using DNA cloning.</u>
Physical mapping is a technique by which physical distance between DNA base pairs can be evaluated with the help of DNA makers and also determine DNA base pairs sequences with high accuracy.
Answer:
YY là kiểu gen trội đồng hợp tử (2 alen Y). Kiểu hình của kiểu gen này có màu hạt vàng. Yy là kiểu gen dị hợp tử (một alen trội, một alen lặn). Kiểu hình của kiểu gen này có màu hạt vàng.
Explanation:
Answer:
the first one would be DNA replication.
the second one would be Segregation
the third is Cytokinesis
and the last should be Binary Fission
