Question

hii....good morning......☺️☺️........what is dominance and ressesive factor​

Answer 1

Answer:

dominant factors are those phenotypic factors which are able to express themselves as a character or trait for eg. long pea plant from mendelian characters and recessive are those which can't express themselves properly eg. dwarf pea plant...

.Mendel noticed that one of the forms of the trait occurred more often in nature - this was the form that always appeared in his first generation of hybrids. He called it the dominant form of the trait; the other was called recessive because it seemed to disappear from some generations. Although the first cross of the two pure strains always resulted in all of the offspring showing the dominant form of the trait, the second generation, the monohybrid cross, always resulted in a three to one ratio of dominant to recessive offspring.

Mendel's ratios were consistent because he used such large numbers of plants (recall that if you flip a coin a few times it may not result in a 50/50 ratio of heads to tails, but the more tosses you do, the closer you will come to that number).

Answer 2

$\huge\underline\mathrm{Hello♡}$

"Alleles are variations of a gene. A capital letter is used to represent the dominant allele and a lower-case letter is used to represent the recessive allele (example: dominant gene = P; recessive gene = p)." For a recessive trait to appear the offspring must receive two recessive genes from the parents.

Thank you❤️
