Which is the best example of a hypothesis leading to new experimental methods? Thomas Hunt Morgan continued the genetic research of Gregor Mendel, but Morgan used fruit flies. The table below summarizes the traits that Mendel examined during his experiments. Traits Studied by Mendel What do these characteristics all have in common? They can all be easily observed. Tall pea plants are dominant over short pea plants. If there are 200 short plants in the F2 generation from a cross tha...

Cystic fibrosis is a genetic disorder. It is a recessive trait that is determined by two alleles. Suppose two parents each carry at least one recessive allele, but neither of them has cystic fibrosis. Which statement reflects the likelihood of a child of these parents having cystic fibrosis? The child may or may not have the disease because a recessive gene from each parent may be passed on. During an experiment, a scientist crosses a pea plant that has purple flowers with a pea plant that has...

Tall pea plants are dominant over short pea plants. If there are 200 short plants in the F2 generation from a cross that followed Mendel's methods, about how many plants will be tall in that generation? 600 If Mendel had crossed a true breeding dominant plant with a true breeding recessive plant, in which of the three generations is the recessive trait visible? P generation and F2 generation If a scientist wanted to follow Mendel's experiment with a different kind of plant, which type ...

Which statement describes Mendel's hypotheses regarding gametes? A gamete carries one allele for a gene. What controls traits and inheritance? nucleic acids Scientists often use fruit flies as a method to test hypotheses about human genes. Why are fruit flies advantageous in the study of human inheritance? They reproduce quickly and take up little space. The flowchart below shows the three generations of a cross between a pea plant that has yellow pods and a pea plant that has green pod...
