(3) A recessive allele always does not produce its

allele y
(4) A dominant allele is always better for an

Answer 1

Answer:

A dominant allele is always better for an organism

Answer 2

"A recessive allele always does not produce its recessive trait when paired with its dominant allele" is true among the given statements. (option 4)

• In a heterozygous individual where a dominant allele is present with a recessive allele, the only dominant trait is expressed.
• As the dominant allele suppresses the expression of the recessive allele leading to the production of its product in less or negligible amounts, further leading to the appearance of only the dominant trait.
• Neither recessive nor dominant traits can be called beneficial or worst.
• It totally depends on which characteristic or trait is selected by nature according to environmental conditions.
