FFA chapter 9 lesson 1

what is gentics

• Genetics is the study of animals and their behavior.
• is the study of how characteristics are passed from one generation to the next

• Genetics is the examination of environmental factors affecting health.
• Genetics focuses solely on physical traits of plants.

what is allel

• An allele is a type of chromosome.
• An allele is a complete set of genes in an organism.
• An allele is a protein that helps in gene expression.
• are alternative forms of the same gene (dominate vs recessive

what are phenotype

• Phenotypes are the evolutionary history of an organism.
• Phenotypes are genetic sequences of an organism.
• Phenotypes are the observable traits of an organism.
• Phenotypes refer to the DNA structure of an organism.

what is genotype

• The genetic make-up of an organism.

• The process of genetic mutation.
• The environment in which an organism lives.
• The physical appearance of an organism.

what is heterozygous

• An organism with two identical alleles for a specific gene.
• A type of mutation in a single allele.
• An organism that has no alleles for a specific gene.
• An organism with two different alleles for a specific gene.

what is homozygouse

• Homozygous is a term used for organisms with only one allele for a gene.
• Homozygous is when an organism has two identical alleles for a gene.
• Homozygous refers to having two different alleles for a gene.
• Homozygous means an organism has no alleles for a gene.

what is recessive

• A recessive trait is always expressed with one copy of the allele.
• Recessive traits can be expressed in the presence of a dominant allele.
• A recessive allele is dominant over all other alleles.
• A recessive trait is expressed only when two copies of the recessive allele are present.

what is dominate trait

• A dominant trait is only expressed when two dominant alleles are present.
• A dominant trait is a trait that is always recessive in nature.
• A dominant trait is a genetic trait that is expressed when at least one dominant allele is present.
• A dominant trait can be expressed without any alleles present.

what is a carrier for genes

• A carrier for genes is an individual who shows symptoms of a genetic disorder.
• A carrier for genes is someone who has two copies of a mutated gene.
• A carrier for genes is an individual who has one copy of a mutated gene.
• A carrier for genes is a type of gene that cannot be passed to offspring.
