What type of trait will only show up if two genes are present?
Recessive alleles only show their effect if the individual has two copies of the allele (also known as being homozygous?). For example, the allele for blue eyes is recessive, therefore to have blue eyes you need to have two copies of the ‘blue eye’ allele.
Does a gamete carry two genes for a trait?
Each gamete will receive one copy of each chromosome and one allele for every gene. When the individual chromosomes are distributed into gametes, the alleles of the different genes they carry are mixed and matched with respect to one another.
When a trait is only expressed in the presence of two identical alleles The genotype is?
Homozygous also refers to a genotype consisting of two identical alleles of a gene for a particular trait. An individual may be homozygous dominant (AA) or homozygous recessive (aa). Individuals who are homozygous for a trait are referred to as homozygotes.
How is genetic continuity maintained between generations of cells?
Genetic continuity between generations of cells in sexually reproducing organisms is maintained by: two types of cell division, mitosis and meiosis. Where is the majority of genetic material located in eukaryotic cells? Nucleus
Which is product law describes the genotype of an organism?
Product law Which of the following terms is used to describe the genotype of an organism that possesses two alleles of the same type for a certain characteristic? Homozygous Sexually reproducing organisms have a diploid chromosome content. What does this mean? There are two copies of each chromosome type in these organisms.
How does one gene influence the development of many phenotypes?
The phenomenon in which a single gene influences the development of many phenotypes is called _____. pleiotropy Compared to standard Mendelian inheritance patterns, what do codominance, partial dominance, lethal Alleles, and epistasis have in common? They alter phenotypic ratios.
Which is normally observed in an F1 hybrid organism?
Allele Which type of trait is normally observed in an F1 hybrid organism? Dominant What is the scientific name of the organism used by Mendel to conduct genetic crosses? Pisum sativum Which hypothesis states that there is no significant difference between the expected outcome of an experiment and the outcome that is actually observed?
