Summary Introduction
Concept Introduction: Independent assortment is one of the laws proposed by Mendel. Mendel proposed the law of independent assortment based on the results of dihybrid cross that “alleles at one locus tend to assort into gametes independently of alleles at other loci”.

- Two pea plants that are true-breeding for recessive white flowers are mated and their offspring analyzed. Which of the following statements about this situation is true? Group of answer choices A)The offspring represent the P generation. B)The gametes produced by the offspring will carry only one allele for this gene. C)Both parents are referred to as heterozygotes. D)Half of the offspring will be true-breeding for white flowers.arrow_forwardAlleles for Tay-Sachs disease are inherited in an autosomal recessive pattern. Why would two parents with a normal phenotype have a child with Tay-Sachs? a. Both parents are homozygous for a Tay-Sachs allele. b. Both parents are heterozygous for a Tay-Sachs allele. c. New mutations gave rise to Tay-Sachs in the child. d. b or carrow_forwardTay–Sachs disease is caused by recessive alleles on anautosome. In which case(s) could two parents with anormal phenotype have a child with Tay–Sachs?a. Both parents are homozygous for a Tay–Sachs allele.b. Both parents are heterozygous for a Tay–Sachsallele.c. One parent is homozygous for a Tay–Sachs allele,and the other is heterozygous.arrow_forward
- Locus heterogeneity means that a genetic disordera. has a heterogeneous phenotype.b. is caused by mutations in two or more different genes.c. involves a structural change in multiple chromosomes.d. is inherited from both parentsarrow_forwardIn humans, color blindness is a sex-linked recessive trait. A female who is a carrier (XBXb) for color blindness has children with a male with normal vision (XBY). Make a Punnett Square to help you answer the questions. What are the chances of their children being color blind? What are the chances of their children being ‘carriers’ for color blindness?arrow_forwardMendel's pea plants were a good choice for studying heredity, because: a) They have lots of easily observable traits that vary in an either-or manner. b) Their mating is uncontrollable. c) There are separate male and female plants. d) The plants are incapable of cross-pollination.arrow_forward
