The principle of dominance is derived from Mendel's conclusions. Which of the following describes the law of segregation?


Some alleles of a gene are dominant, and others are recessive
If the recessive allele appears on one of the genes, the offspring will display the trait
Both dominant alleles need to be present for the offspring to inherit the dominant trait
Only 1
1, 2, and 3
2 and 3
1 and 2

Answer:

Only 1

Explanation:

"Some alleles of a gene are dominant, and others are recessive" is the only true statement here. The other two, "If the recessive allele appears on one of the genes, the offspring will display the trait" and "Both dominant alleles need to be present for the offspring to inherit the dominant trait" can each be ruled out easily with the former being that both recessive alleles have to appear for the offspring to display the trait and the latter being that a dominant and a recessive can work with the dominant still showing.

The statement 'some alleles of a gene are dominant, and others are recessive' is CORRECT.

An individual receives one particular gene variant or 'allele' from each parent.

A homo-zygous is an individual that exhibits two identical 'alleles' at a particular gene locus.

Conversely, a heterozygous is an individual that exhibits two different alleles at a particular gene locus.

Complete dominance occurs when one dominant allele completely masks the expression of the recessive allele for a particular gene locus.

In conclusion, the statement 'some alleles of a gene are dominant, and others are recessive' is CORRECT.
