Question

complete the table to indicate whether each statement is true or false.

1. sometimes one allele overpowers another, while other times both alleles are partially or completely expressed to produce observable traits.
2. sexual reproduction allows populations to produce greater numbers of offspring at once.
3. two homologous chromosomes in a somatic cell always contain the same alleles, but may contain different genes.
4. during fertilization, haploid gametes combine to form a diploid zygote.
5. during asexual reproduction, offspring get half their dna from each parent.

Explanation:

1. Allele expression includes complete dominance (one allele overpowering another), incomplete dominance (partial expression of both), and codominance (full expression of both), all leading to observable traits.
2. Asexual reproduction typically produces far more offspring at once than sexual reproduction, which requires mating and fewer gamete fusions.
3. Homologous chromosomes in a somatic cell carry the same genes (in the same loci) but can have different alleles for those genes.
4. Gametes are haploid (1 set of chromosomes, $n$); their fusion during fertilization creates a diploid zygote with 2 sets of chromosomes ($2n$).
5. Asexual reproduction involves only one parent, so offspring inherit an identical copy of the parent's DNA, not half from two parents.
