Alleles, genes and loci are different names for the same thing. correct answer: False The genotype is the physical appearance of a trait. correct answer: False The phenotype of a dominant allele is never seen in the F1 progeny of a monohybrid cross. correct answer: False Mendel's experiments involved both discrete qualitative traits and continuous quantitative genetic traits. correct answer: False The two alleles in pea plants are divided among the gametes with equal probability...

Mastering Genetics 3,4,9,10,11 What is the basis for homology among chromosomes? - ANSWER- type and location of genes Polydactyly is expressed when an individual has extra fingers and/or toes. Assume that a man with six fingers on each hand and six toes on each foot marries a woman with a normal number of digits. Having extra digits is caused by a dominant allele. The couple has a son with normal hands and feet, but the couple's second child has extra digits. What is the probability that ...
