The cross L p q / l P Q × l p q / l p q is carried out. If the L gene is in the middle, between genes P and Q, what would be the genotypes of the double crossover gametes in this cross?Question 12Answera. L p q and l P Qb.L P Q and l p qc.L p Q and l P qd.cannot be determinede. l p Q and L P q

Alleles A and B are linked on chromosome 1 (such that you have A-B and a-b). Alleles C and D are linked on chromosome 2 (you have C-D and c-d). If a crossover event does not occur between either set of genes, which gamete genotype could NOT be produced by an individual heterozygous at each locus?

If crossing over occurs only between the two alleles of the same gene, as shown in the animation, what allele combinations are present in the gametes?Multiple Choiceone gamete with a parental combination of alleles, and three recombinant gametesfour gametes with parental combinations of allelesfour recombinant gametestwo gametes with parental combinations of alleles, and two recombinant gametes

In a cross, an individual with an unknown genotype is mated with an individual with a homozygous recessive genotype to determine the unknown genotype.

The map of a chromosome interval is:A——10 m.u.——B——40 m.u.——CFrom the cross A b c / a B C × a b c / a b c, how many double crossovers would be expected out of 1000 progeny, if no interference is present?Question 11Answera.20b.40c.5d.10e.80

Fill in the Blank QuestionFill in the blank question.A cross is a mating between two individuals that are both heterozygous for the same, single gene.
