Exam 11: Patterns of Inheritance

Based on this figure, what is the genotype of an individual pea plant that is homozygous for green pod and constricted pod and is 6 feet tall? (Assume that green and yellow pods are indicated by G and g, inflated and constricted pods by I and i, and height by T and t.)

Which of the following conditions may cause infertility in a human?

Sex-linked traits affect only sexual characteristics.

A human sperm cell possesses autosomes and

Albinism results from a recessive allele. Which of the following describes the expected offspring from a normally pigmented male (who had an albino father) and an albino wife?

Blood typing is often used as evidence in paternity cases in court. In one case, the mother had blood type B and the child had blood type O. Which of the following blood types could the father NOT have?

Which of the following is the most common chromosome disorder among live -born infants?

According to the law of segregation

Crossing smooth-seeded pea plants with wrinkled-seeded pea plants resulted in progeny that all had smooth seeds. This indicates that the wrinkled-seed trait is

When alleles on a pair of homologous chromosomes move into different gametes during meiosis, this demonstrates

Which of the following is a sex-linked recessive condition?

In Mendel?s experiments, if the gene for tall (T₁) plants was incompletely dominant over the gene for short (T₂) plants, what would be the result of crossing two T₁T₂ plants?

A man who carries a harmful sex-linked (on the X chromosome) gene will pass the gene on to

A Mendelian test cross is used to determine whether

Suppose you cross a pea plant with yellow, smooth seeds with one that has green, wrinkled seeds. You examine the seeds of 967 offspring and find that some have yellow, smooth seeds and some have yellow, wrinkled seeds, but no green seeds of either type show up. What is the genotype of the yellow-seeded parent? (Y = yellow, y = green; S = smooth, s = wrinkled)

The wavy hair in children of straight-haired and curly-haired parents results from a pattern of inheritance called__________ .

Peas were a good organism of choice for Mendel because

Although the law of independent assortment is generally applicable, when two loci are located physically close to each other on the same chromosome, the phenotypes of the offspring sometimes do not fit the phenotypes predicted. This is due to

The failure of chromosomes to segregate properly during meiosis is called

A recessive allele on the X chromosome causes color deficiency. A color-deficient boy has a mother with normal vision and a color-deficient father. From which parent did he get the color-deficiency gene?
