Mendel worked with pea plants that showed complete dominance for several traits. He was able to check his hypotheses about how inheritance works. He determined that traits are caused by two (? ) factors - one from the mother and one from the father. ?= form of allele that will mask the recessive ?= form of allele that will not show unless both alleles are recessive. ?= sections of a chromosome that code for proteins (and show up as traits)....

Question 1 (1 point) In a species of flowering plant, petal color is determined by one gene with two alleles, R and W. Individuals homozygous for allele R have red petals, and those homozygous for allele Whave white petals. Ris dominant to W. You cross a pure- breeding red flowered plant with a pure-breeding white flowered plant to create an F1 generation. You then cross two individuals from the F1 generation to create an F2 generation. What proportion of the...
