1) Imagine a cross between two individuals whose genotypes for six independently segregating loci are (P#1) AABbCcddEeFf and (P#2) AabbCcDDEeFf. For each locus, upper case letters indicate dominant traits; lower case letters indicate recessive traits. (That is, genotypes AA and Aa give phenotype “A”; genotype aa gives phenotype “a.”) P#1 means parent number 1, and P#2 means parent number 2.(a) How many different types of gametes can each parent produce? How many different entries would there be in a Punnett Square for this cross?(b) How many different phenotypes and genotypes can result from this cross?(c) What fraction of the progeny will be phenotypically identical to parent P#1. What fraction will be genotypically identical to the parent P#2?(d) What fraction of the progeny will be homozygous at all six loci? What fraction will be heterozygous at exactly five of the six loci?

An allele could also be a variant form of a gene. Some genes have a spread of varied forms, that…

regating loci are (P#1) AABbCcddEdFf and (P#2) AabbCcDDEdFf. F per case letters indicate dominant traits; lower case letters indicate ts. (That is, genotypes AA and Aa give phenotype "A"; genotype aa enotype "a".) P#1 means parent number 1, and P#2 means parent n (a) How many different types of gametes can each parent produ

O All three genes are linked, but need to do more crosses and data to determine the gene order. All three genes are linked with the flower color gene (F) in the middle. All three genes are linked with the seed weight gene (S) in the middle. All three genes are linked with the leaf size gene (L) in the middle.

[The allele symbols stand for thefollowing: A = agouti, a = solid (nonagouti); B = blackpigment, b = brown; C = pigmented, c = albino; D =nondilution, d = dilution (milky color); S = unspotted,s = pigmented spots on white background.]
