7. L. 4 A. 3 Develop and use models (Punnett squares) to describe and predict patterns of the inheritance of single genetic traits from parent to offspring (including dominant and recessive traits, incomplete dominance, and codominance).

Punnett Squares are used to demonstrate and predict patterns in the inheritance of single

Punnett Squares are used to demonstrate and predict patterns in the inheritance of single genetic traits. • A cross that shows the inheritance of a single characteristic is known as a monohybrid cross. • If the two alleles are the same (TT or tt), the genotype is considered homozygous. • If the two alleles are different (Tt), the genotype is considered heterozygous (also referred to as hybrid).

Punnett squares are used to predict the ratio or percentage of the possible genes

Punnett squares are used to predict the ratio or percentage of the possible genes that an offspring will have based on the genotype of the parents. • In a Punnett square, the top of the table shows the alleles provided by one parent. • The alleles for the other parent are placed along the left side of the table. • One allele from each parent is placed in the individual squares, forming a new gene pair. • The individual squares show the possibilities of allele pairs in the offspring.

 • In this example, tallness (T) is the dominant trait and shortness (t)

• In this example, tallness (T) is the dominant trait and shortness (t) is the recessive trait. • As the Punnett square shows, TT, Tt, and tt are all possible genotypes for the height of the offspring. • The offspring with the genotypes TT and Tt will have a phenotype of tall; the offspring with the genotype of tt will have a phenotype of short. It is difficult to predict most traits in humans (for example hair color or eye color) because there are multiple alleles that control these traits.

Incomplete Dominance • Incomplete dominance is a condition when the dominant allele does not

Incomplete Dominance • Incomplete dominance is a condition when the dominant allele does not completely mask the recessive. • As a result some of the recessive trait will be observed in the phenotype. An example of an incomplete dominance in plants may be color of flowers. • The color red is dominant over the recessive color white. Pink flowers are a result of a blending of red and white.

Co-dominance • Co-dominance is a condition when there is more than one dominant allele.

Co-dominance • Co-dominance is a condition when there is more than one dominant allele. • As a result, both alleles will be expressed in the phenotype. • An example of co-dominance in plants may be the color of the flowers. • If both red and white alleles are dominant, both traits will be expressed in the flower. • The AB blood type in humans is another example of co-dominance.

RAM –Ready And Motivated Friday, 03 -02 -2020 Why is it important that we know about genetic diseases before we see them? Treatment, how soon something comes to light that can affect someone’s long term care and knowing what your chances are for passing your genes on to your children. What is the name of the genetically linked rare blood disorder? Hemophelia

In fruit flies, long wings are dominant over short wings. A scientist crossed a purebred long-winged fruit fly with a purebred short-winged fruit fly. 1. If W stands for long wings, write the symbols for the alleles of each parent fly. 2. What will be the wing length of the F 1 offspring? 3. If the scientist crosses a hybrid male F 1 fruit fly with a hybrid F 1 female, what will their offspring probably be like?

How Are Genetic Disorders Inherited in Humans? A genetic disorder is an abnormal condition

How Are Genetic Disorders Inherited in Humans? A genetic disorder is an abnormal condition that a person inherits through genes or chromosomes. Some genetic disorders are caused by mutations in the DNA of genes. Other disorders are caused by changes in the overall structure or number of chromosomes.

How Are Genetic Disorders Inherited in Humans? Cystic fibrosis is a genetic disorder in

How Are Genetic Disorders Inherited in Humans? Cystic fibrosis is a genetic disorder in which the body produces abnormally thick mucus. In the lungs, this can cause difficulty breathing. A person with cystic fibrosis inherits one mutated allele from each parent.

How Are Genetic Disorders Inherited in Humans? In Down syndrome, instead of a pair

How Are Genetic Disorders Inherited in Humans? In Down syndrome, instead of a pair of chromosomes, a person inherits three copies of chromosome 21. People with Down syndrome experience some degree of mental retardation and often have heart defects.

How Are Genetic Disorders Inherited in Humans? Sickle-cell disease and hemophilia are both blood

How Are Genetic Disorders Inherited in Humans? Sickle-cell disease and hemophilia are both blood disorders. In sickle cell disease, a mutation produces abnormal hemoglobin, a protein in red blood cells. The cells carry less oxygen than normal cells and have a crescent or sickle shape that causes them to clog blood vessels. While a person with just one sickle-cell allele will produce both normal and abnormal cells, a person with two sickle-cell alleles will show symptoms of the disease.

How Are Genetic Disorders Inherited in Humans? Hemophilia slows or prevents blood clotting so

How Are Genetic Disorders Inherited in Humans? Hemophilia slows or prevents blood clotting so that even small bumps can cause bleeding. Because hemophilia is caused by a recessive allele on the X chromosome, it is more common in males than females.
