Sickle-cell disease is a recessive trait in humans. In a cross between a father who has sickle-cell disease and a mother who is heterozygous for the sickle-cell allele, what is the probability that all of their first three children will be unaffected? A) 1/4 B) 1/2 C) none D) 1/8 E) 1/16

Is there anything that you can't inherit from your parents? Select the traits in the list below that do NOT have a genetic component. In biology a heritable trait is one where offspring resemble their parents in a predictable way, and this carries on across generations. a)Group of answer choices b)Hair color c)Accent when speaking d)Fashion sense e)Height f)Personality g)Musical taste h)Genetic disorders

The first experiment of Mendel considering the inheritance of a single trait is called________.a) Hybrid crossb) Monohybrid crossc) Polyhybrid crossd) Dihybrid cross

Imagine a test cross of an unknown individual that results in all 1000 offspring being homozygous recessive for the two traits in question. What is the genotype of the unknown?A) Homozygous dominant for both genes. B) Homozygous dominant for one gene and homozygous recessive for the other.C) Heterozygous for both genes.D) Heterozygous for one gene and homozygous recessive for the other.E) This scenario cannot exist.

When a pair of alleles that an individual carry are the same, the person is said to be_____ for the trait a ) Polygenic b) Homologous c ) Autosomous e ) Homozygous

We now understand that there are exceptions to Mendel's principles. For example, the inheritance pattern where two or more genes do NOT assort independently because they are on the same chromosome is called: a) Mendelian inheritance b)linkage c)genomic imprinting d) dominance e) epistasis

1. An offspring that contains both recessive genes for a trait is called A) inbred B) homozygous C) heterozygous D) mutated    2. Why is water considered a polar molecule? A) The oxygen atom is found between the two hydrogen atoms. B) The oxygen atom attracts the hydrogen atoms. C) The oxygen end of the molecule has a slight negative charge, and the hydrogen end has a slight positive charge. D) Both hydrogen atoms are at one end of the molecule, and the oxygen atom is at the other end. 3. An offspring that contains both recessive genes for a trait is called A) inbred B) homozygous C) heterozygous D) mutated 4. Sugar dissolves when stirred into water. The sugar is the ________, the water is the ________, and the sweetened water is the ________. A) solution... solvent... solute B) solute... solvent... solution C) solvent... solute... solution D) solution... solute... solvent

When Mendel examined the inheritance of pod colour, he crossed true- breeding green and true-breeding yellow plants. All of the plants produced were yellow. He then crossed the yellow plants and found that some of the offspring were green and some were yellow. What did he conclude from this? * O a) yellow is dominant to green O b) the F1 generation was heterozygous c) each trait has two factors all of a, b, andc both a and c

Question 12 Could a person could carry a harmful allele of an imprintable gene but not show the associated phenotype? O A) ye s B) no Question 16 For which of the following extensions of Mendelian concepts or non-Mendelian concepts would a Punnett square be ineffective for determining the genotypes of offspring from a known cross? O A) maternal effect inheritance B) 'mitochondrial inheritance C) imprinting D) sex-linked inheritance E) all of the above CS Scanned with CamScanner

A cross is set up: Gg Hh× Gg Hh. What fraction of offspring from this cross will be the GgHh genotype? A) 1/16 B) 4/16 C) 5/16 D) 9/16 E) 3/16
