A man with blood group A marries a woman with blood group O, and their daughter has blood group O. Is this information enough to tell you which of the traits – blood group A or O – is dominant? Why or why not?

We cannot determine which blood group A or O’s traits are more prevalent based solely on the information provided. When it comes to ABO blood, blood type A is always dominant and blood type O is always recessive. Here, the mother’s blood group may be OA or OO, whereas the father’s blood group could be …

. How do Mendel’s experiments show that traits are inherited independently?

Mendel’s dihybrid cross experiment demonstrates that characteristics are inherited independently. He used two characteristics in the experiment: seed shape and seed colour. While the round shape (RR) dominates over the wrinkled shape, the colour yellow (YY) dominates over green (YY) (rr). There were nine plants with round yellow (RRYY) seeds, three plants with round green …

How do Mendel’s experiments show that traits may be dominant or recessive?

Mendel’s experiments on the mono-hybrid cross showed that the traits could either be dominant or recessive. He experimented the experiment by crossing tall (TT) and dwarf (tt) pea plants. The F1 (or filial) generation was represented by the plants that emerged as the result of fertilisation. The F1 plants were all very tall. Mendel continued by …

What are Ethylene plant hormones and their functions?

 Ethylene Plant Hormone Both an inhibitor and a growth promoter, it works. takes the form of gas. It is created in tissues going through senescence and in ripening fruits. It is one of the most commonly utilised hormones in agriculture and controls a number of physiological processes. Functions Ethylene Plant Hormone: (i) It accelerates fruit ripening.(ii) …

What are Abscisic acid and its functions?

Abscisic Acid  It is a hormone that inhibits growth. GAs are counterbalanced by ABAs. It promotes dormancy and abscission by inhibiting plant metabolism. Because it raises plants’ stress tolerance, it is also known as “stress hormone.”  Abscisic acid (ABA). Functions of Abscisic acid: (i)causes leaves and fruits to fall off (ii) inhibits the germination of seeds …
