Answers
Answer:
Genetics refers to the study of genes and the way that certain traits or conditions are passed down from one generation to another. Genomics describes the study of all of a person's genes (the genome).
Genes carry the information that determines your traits (say: trates), which are features or characteristics that are passed on to you — or inherited — from your parents. Each cell in the human body contains about 25,000 to 35,000 genes.
Each cell within the square is representative of one possible genotypic outcome for any offspring. The term genotype refers to the genetic make-up of an organism. Genotype is represented by using letters of the alphabet to stand for each allele that has been passed from the parents.
In a broad sense, the term "genotype" refers to the genetic makeup of an organism; in other words, it describes an organism's complete set of genes. Each plant's genotype contributes to its phenotype, which, in this case, is the outward appearance of its flowers.
Explanation:
1. Genetics is the study of heredity.
- Genetics is the study of heredity, the passing of traits from one generation to the next. It encompasses the study of genes, their function, and how they are inherited, expressed, and regulated.
2. Traits are characteristics that can be passed only from a parent thing to its offspring.
- In genetics, an offspring inherits genetic information from its parents, which determines its physical and biological traits.
3. Each cell of a Punnett square represents one possible genetic outcome for any offspring of two specific parents.
- A Punnett square is a grid used to predict the possible genotypes of offspring resulting from a cross between two individuals, based on their known genotypes.
4. Genotype refers to the genetic makeup of an individual organism.
- It includes all of the genetic information that an individual inherits from its parents, including both dominant and recessive alleles for each gene.
5. Phenotype refers to the physical trait that is expressed in an individual.
- Phenotype is the observable characteristics or traits of an individual that result from the interaction of an individual's genotype and environmental factors.
6. When the expression of one allele is masked by the presence of another, it is said to be recessive.
- Recessive alleles are those that are not expressed when present with a dominant allele in a heterozygous individual.
