What are the basic principles of Mendelian genetics?

Answer 1

- Inheritance of biological characteristics is determined by genes, which are passed from parents to their offspring

- In cases of two or more forms (alleles) of the gene for a single trait exist some forms of the gene may be dominant and others may be recessive

- Most sexually reproducing organisms, each adult has two copies of each gene-one from each parent. These genes are segregated from each other when gametes are formed

- The alleles for different genese usually segregate independently of one another

Answer 2

# Sex cell of a plant or animal may contain one factor (allele) for different traits but not both factors needed to express the traits. # Characteristics are inherited independently from other characteristics. # Each inherited characteristic is determined by two heredity factors/genes, one from each parent which determine whether a gene will be dominant or recessive.

Answer 3

Mendel's principles of genetics includes the law of segregation and the law of independent assortment.

The law of segregation states that the two alleles of a gene separates into different gametes during gamete formation.

The law of independent assortment states that each pair of alleles separates independently of each other during formation of gametes.

Answer 4

The phenotype of an organism (how it looks) is determined by two genetic alleles. Each parent has two alleles and passes one on to its child. In other words, the child will have two alleles, one from each parent. There is a dominant and recessive gene for each characteristic. Only one dominant allele is needed for that phenotype to be expressed in the organism. An example of this would be if one parent is homozygous dominant (has two dominant alleles) for brown eyes. The other parent is homozygous recessive (has two recessive alleles), so they have blue eyes. This can be shown as: BB x bb. The children will be heterozygous (one of each), but will have brown eyes since a dominant gene is present. This genotype can be shown as: Bb.
