if you are heterozygous for the hair color gene, you might have one copy of the blonde hair allele and one copy of the brown hair allele. Because the brown hair allele is dominant, you will have brown hair.
When an organism isheterozygousfor a particular trait, how that trait develops or is expressed depends on things like whether a gene isdominantorrecessive, as well as simple mathematical odds. New vaccines under development have put the termsDNA,RNA, andmRNAin the spotlight. Learn what each word...
Alternative forms of a given gene are called alleles, and they can be dominant or recessive. When an individual has two of the same allele, whether dominant or recessive, they are homozygous. Read Homozygous vs. Heterozygous | Definition & Differences Lesson ...
Dominant traits like whether you can roll your tongue or have a genetic predisposition to developing Huntington's disease only require one dominant allele to express. This means that people with homozygous dominant alleles (AA) and heterozygous alleles (Aa) express those traits, but people with hom...
Learn about the definition of homozygous dominant and the homozygous dominant genotype. Discover homozygous dominant examples that occur in the...
Heterozygous means that an organism has two different alleles of a gene. For example,pea plants can have red flowersand either be homozygous dominant (red-red), or heterozygous (red-white). If they have white flowers, then they are homozygous recessive (white-white). Carriers are always heter...
Answer to: A dominant gene expresses itself in either the homozygous or heterozygous state. ___ A. True B. False By signing up, you'll get...
Step-by-Step Solution:1. Understanding Dominant Genes: A gene is termed dominant if it can express its trait in both homozygous and heterozygous conditions. This means that the dominant gene will show its effec
Finally the remaining SNVs and INDELs of the index patient were checked for the three modes of inheritance: Autosomal dominant (de novo?), autosomal recessive, X-linked recessive or dominant and the coverage (minimum 20x). Sanger sequencing of the TBCK gene was performed on genomic DNA from ...
