A human with heterozygous genotype can have a dominant phenotype if one of the alleles complete mask the effects of the other.
- Heterozygous genotype involves two different alleles, unlike homzygous genotypes in which the alleles are the same.
- When the two alleles of an heterozygous genotype exert equal effects on one another, they are said to be codominant.
- When one of the alleles of an heterozygous genotype incompletely exert its effects on the other allele, it is said to be incomplete dominance.
- When one of the alleles complete dominates and masks the effects of the other allele, it is said to be dominant.
Hence, a dominant allele will always produce a dominant phenotype even if the genotype of the organism is heterozygous.

Answer:
<em>The correct option is A) Travis's mother, who lives with him</em>
Explanation:
We all know that humans reproduce sexually. The zygote formed consists half of the chromosomes or genome from the mother and half from the father. Hence, the sex cells undergo meiosis so that the chromosome number could be reduced to half in the sex cells.
However, the mitochondria present in a cell have their own DNA and instead of both parents being transferring this DNA, the mitochondrial DNA is just transferred by the mother to the offsprings. Hence, the mitochondrial DNA of mother and child will be the same.
Answer:
The spindle, shown in figure below, consists of fibers made of microtubules. the spindle starts to form during prophase of mitosis kinetochores on the spindle attach to the centromeres of sister chromatids.
Explanation: Chromosomes line up at the metaphase plate under tension from the mitotic spindle.
