|
|
Some alleles are dominant over others.
|
|
|
Allele pairs separate during gamete formation and randomly unite at fertilization.
|
|
|
During gamete formation genes for different traits separate without influencing each other’s inheritance
|
|
|
None of the above
|
Detailed explanation-1: -This law states that in a heterozygous condition, the allele whose characters are expressed over the other allele is called the dominant allele and the characters of this dominant allele are called dominant characters. The characters that appear in the F1 generation are called as dominant characters.
Detailed explanation-2: -First, the Law of Dominance and Uniformity states that some alleles, which are variants of a particular gene found at the same chromosomal locus or location, are dominant over the other alleles for a given gene. Those traits that are not dominant are termed recessive.
Detailed explanation-3: -The Law of Dominance says that when an organism is heterozygous for a trait (meaning it has two different alleles for that gene), the allele that is expressed is the dominant one.
Detailed explanation-4: -In codominance, neither allele is dominant over the other, so both will be expressed equally in the heterozygote.
