- There are several forms of allelic genes interaction. At one of the forms a homozygous and a heterozygous organisms have the same phenotype. Which of the below mentioned forms of gene interaction can it be? Select one: a. Complete dominance c. Incomplete dominance d. Complementarity e. Codominance O b. Overdominancearrow_forwardIf black and white true-breeding mice are mated and the result is all gray offspring, what inheritance pattern would this be indicative of? a. dominance b. codominance c. multiple alleles d. incomplete dominancearrow_forwardA walnut comb rooster is mated to three hens. Hen A, which has a walnut comb, has offspring in the ratio of 3 walnut to 1 rose. Hen B, which has a pea comb, has offspring in the ratio of 3 walnut to 3 pea to 1 rose to 1 single. Hen C, which has a walnut comb, has only walnut comb offspring. What are the genotypes of the rooster and the three hens?arrow_forward
- How would the genotypic and phenotypic ratios be affected if the mode of inheritance is a. incomplete dominance? b. co-dominance?arrow_forwardCompare and contrast the following pairs, include examples: 1. Genotype vs. Phenotype 2. Heterozygous vs. Homozygous 3. Dominant vs. Recessive genes 4. Codominance vs. Incomplete dominancearrow_forwardA couple both with blue eyes have a kid with brown eyes. In this case, the eye color is determined by the amount of melanin produced. Brown eyes have more melanin while blue eyes have much less. Which of the following is the mostly likely explanation for this phenomenon? A. Incomplete dominance B. Allelic series C. Complementation D. All of the abovearrow_forward
- A man with type A blood marries a woman with type B. Their offspring all have type AB blood. The pattern of inheritance is called A) codominance. B) sex-linkage. crossing over. incomplete dominancearrow_forwardThe AB blood type in the ABO blood group is an example of a. dominant versus recessive alleles. b. incomplete dominance. C. codominance. d. a polygenic trait. e. sex-linked inheritance.arrow_forwardA snake with 30 vertebrae is crossed to a snake (same species) with 24 vertebrae. Their offspring all have 27 vertebrae. When two of the F1 are crossed to one another the F2 snakes mostly have 26-28 vertebrae but some have as many as 30 or as few as 24. What type of inheritance is being shown in this example? Group of answer choices A. multiple loci, additive B. single locus, complete dominance C. codominance D. epistasis E. single locus, incomplete dominancearrow_forward
- The chart below is showing 4 generations of a family that is affected by a hereditary disease. a. Is the disorder being tracked dominant or recessive? How do you know? b. There is only one possible genotype for person C. True or False? c. What are the possible genotypes for person A? d. What are the possible genotypes for person B?, e. If two people with the same genotypes as person C's spouse and person A's spouse had a child, what is the probability that the child will be affected by this genetic disorder? (draw a Punnett square using the correct genotypes to help you). % chance offspring will be affected % chance offspring will not be affectedarrow_forwardIn certain cactus, prickly spines can be two-pronged or one-pronged. If a homozygous one-pronged cactus is crossed with a homozygous two-pronged cactus, the F1 generation has a mixture of spines (some are two-pronged, some are one-pronged). a. What are the genotypes of the parents and F1s?b. What mode of inheritance is exhibited? c. If the F1s were crossed, what proportion of the F2s will have genotypes like their parents?arrow_forwardA type of baldness is sex –limited such that the allele that causes it is dominant in men and recessive in women. Thus baldness is much more common in men than women even though the locus is on an autosome. How is the pattern of inheritance in this example different from X-linked inheritance of a recessive allele? Group of answer choices A. the trait can be passed from fathers to sons B. the trait can be passed from fathers to daughters C. the trait can be passed from mothers to sons D. the trait can be passed from mothers to daughtersarrow_forward
