What is a genotype quizlet?

genotype. an organism’s genetic makeup, or allele combinations.

What determines the genotype of an organism?

Many physical traits like hair color and texture, eye color, and skin color are determined by the genotypes that parents pass down to their children. In one sense, the term “genotype”—like the term “genome”—refers to the entire set of genes in the cells of an organism.

What is mendel’s principle of segregation?

The Principle of Segregation describes how pairs of gene variants are separated into reproductive cells. The segregation of gene variants, called alleles, and their corresponding traits was first observed by Gregor Mendel in 1865. Mendel was studying genetics by performing mating crosses in pea plants.

What is phenotype anthropology quizlet?

Phenotype: Detectable expression of the genotype. An expressed and observable trait. e.g. hair color. Examples: Hair color, eye color, weight, the ability to roll one’s tongue. Depends upon: Genotype and the influence of the environment.

What are homozygous alleles quizlet?

homozygous. an organism that has two identical alleles for a trait (purebread) phenotype.

What is an allele apex answers?

One of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome.

What is the definition of heredity in science?

heredity, the sum of all biological processes by which particular characteristics are transmitted from parents to their offspring.

What is codominance inheritance?

​Codominance Codominance, as it relates to genetics, refers to a type of inheritance in which two versions (alleles) of the same gene are expressed separately to yield different traits in an individual.

When the genotype consists of a dominant and a recessive allele the phenotype will be like?

When there is a genotype that consists of a dominant and a recessive allele, the phenotype generally looks like the dominant one.

What is a genotype in anthropology?

genotype. Definition. the genetic makeup of an organism; the combination of alleles for a given gene. Term. phenotypes.

What is heterozygous in biology quizlet?

heterozygous. an organism that has two different alleles for a trait (hybrid)

What is incomplete dominance Codominance quizlet?

incomplete dominance. neither allele is completely dominant over the other so they mix, no dominant or recessive alleles (pink flowers) codominance. two alleles affect the phenotype in separate distinguishable ways, neither allele can mask the other and both are expressed in the offspring (speckled chickens)

What is chromosome in Brainly?

Explanation. Rod-shaped structures are found inside the nucleus of the cell is called a chromosome. These chromosomes are like in the structure of a thread which is present in the nucleus of both plants and animals. The Chromosome is formed of protein and deoxyribonucleic acid (DNA) which is a single molecule.

Which is a characteristic of a population at Hardy-Weinberg equilibrium?

When a population is in Hardy-Weinberg equilibrium for a gene, it is not evolving, and allele frequencies will stay the same across generations. There are five basic Hardy-Weinberg assumptions: no mutation, random mating, no gene flow, infinite population size, and no selection.

What is heterozygous allele?

​Heterozygous Heterozygous, as related to genetics, refers to having inherited different versions (alleles) of a genomic marker from each biological parent. Thus, an individual who is heterozygous for a genomic marker has two different versions of that marker.
