Which pedigree symbol represents a female carrier?

What best describes human eye color?
Answer: The most appropriate answer would be option 2. In humans, the color of the eyes was thought as a simple Mendelian trait however, it has been found that the color of the eye follows polygenic inheritance, that is, it is determined by multiple genes.
When two alleles are the same this is called?
If the two alleles are the same, the individual is homozygous for that gene. If the alleles are different, the individual is heterozygous. Though the term allele was originally used to describe variation among genes, it now also refers to variation among non-coding DNA sequences.
What violates Mendel’s law of segregation?
In any trisomy disorder, a patient inherits 3 copies of a chromosome instead of the normal pair. This violates the Law of Segregation, and usually occurs when the chromosomes fail to separate during the first round of meiosis. A heterozygous pea plant produces violet flowers and yellow, round seeds.
