Question

In a test cross with a double heterozygote, the phenotype of the predominant progeny will depend on whether the alleles are in the trans or cis configuration. True or False?

Answer 1

True. In a test cross with a double heterozygote, the phenotype of the predominant progeny will depend on whether the alleles are in the trans or cis configuration.

Step-by-step explanation:

True. In a test cross with a double heterozygote, the phenotype of the predominant progeny will depend on whether the alleles are in the trans or cis configuration.

In the trans configuration, where the two dominant alleles are on one chromosome and the two recessive alleles are on the other chromosome, the predominant phenotypes in the progeny will be those expressing the dominant traits.

In the cis configuration, where one dominant and one recessive allele are on each chromosome, the predominant phenotype will be heterozygous, with equal proportions of individuals expressing the dominant and recessive traits.
