In humans, the males decide the sex of the infant. In contrast to females, who have XX chromosomes, males have XY chromosomes. Therefore, if When the X chromosomes of the male and female combine, a daughter is born as a result.When the Y chromosome of the male and the X chromosome of the female combine, …

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 …
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 …

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 …

The species may better adapt to environmental changes thanks to genetic variation. Moreover, it is a crucial force in evolution because it allows natural selection to increase the frequency of alleles. These differences will determine whether the species survives or becomes extinct.
Trait B is more probable, Compared to trait A, trait B is more likely to emerge early since it has been existing and replicating in a larger percentage of the population.
