Question
what is the blending theory of inheritance?
A)Mendel's theory of how the traits of parents are passed to offspring through the gametes
B)an old theory that said that offspring show traits intermediate between those of parents.
C)the modern theory of how genetic information is passed from parents to offspring
D)Darwin's theory of how traits are passed from all parts of the parent's body into the gamete to be transmitted to the offspring

- A) Identify two (2) differences between a genetic cross in humans and Mendel's experiments in peas. B) How to explain, in recessive diseases linked to the X chromosome, that there is a generation jump between affected individuals in the lineage of a family? Briefly explain in your own words. Your explanation should be clear and precise. You could draw lineage to illustrate your point.arrow_forwardWhen 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 ) Homozygousarrow_forwardThere are two alleles for the height gene, T for tall and t for short. One parent is a heterozygote, while the other is a recessive homozygotes. Which genotypes, and at which frequencies, are possible from these two parents. a.) 100% heterozygotes b.) 100% dominant homozygotes c.) 50% dominant homozygotes, 50% recessive homozygotes d.) 50% dominant homozygotes, 50% heterozygotes e.) 50% heterozygotes, 50% recessive homozygotes f.) 25% dominant homozygotes, 50% heterozygotes, 25% recessive homozygotes g.) 100% recessive homozygotesarrow_forward
- Why are toy poodles and rotweilers (dog breeds) members of the same species? A) They can mechanically breed with one another B) Their chromosomes and genes align. All of these D) They can produce offspring that are able to produce offspringarrow_forwardWe 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) epistasisarrow_forward1. 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.

- One example of codominance found in animals is the speckled chicken. This organism has alleles for both black and white feathers. What is the probability that the cross between two speckled chicken will result to white feathered chicken? Explain. A) 50% B) 75% C) 25% D) 100%arrow_forward7)Homozygote is a)an individual who has two copies of the same allele for a particular gene b)an individual who has to different alleles for a particular gene c)an individual who has one copy of the most common allele for a particular gene d)an individual who has one copy of the least common allele for a particular genearrow_forwardPart 1: Make a three part process drawing (like a cartoon strip) to demonstrate Mendel's Principle of Segregation. Use two parents with homologous chromosomes marked with alleles "A" and "a". Circle and label these three action parts of the Principle of Segregation: a) parents are diploid, b) alleles separate to form haploid gametes (indicate when this happens), and c) gametes from each parent combine at random to form diploid offspring Part 2: Use the cross Aa x Aa and a Punnett square to demonstrate Mendel's Principle of Segregation. Circle and label these three action parts of the Principle of Segregation: a) parents are diploid, b) alleles separate to form haploid gametes and c) gametes from each parent combine at random to form diploid offspring. Part 3: Use homologous chromosomes marked with alleles "A" and "a" and a second pair of homologs marked with alleles "B" and "b". to demonstrate Mendel's Principle of Independent Assortment in cells in Meiosis.
