Ala lao) 3. You have been growing roses in your greenhouse for years trying to produce deep
red flowers. In roses, the dominant flower color is red (R) while the recessive
flower color is white (r). You discover a wild rose with deep red flowers that you
would like to cross with your greenhouse roses but you don't know the wild rose's
genotype. You decide to do a testcross to figure out the wild rose's genotype. When
you do your testcross, what should be the genotype of the greenhouse rose that you
cross with the wild rose? Half of the offspring from the testcross have red flowers
while the other half of the offspring have white flowers. What genotype is the wild
rose?

For the first question about which greenhouse flower to use, it's the white ones. For the second question about wild genotype, it's heterozygous (probably).

Explanation: White flowers for the test cross because test crosses always use the genotypes with two recessive alleles. And the wild roses must be heterozygous because they produced half white flowers. The only way to produce more rr genotypes after a cross is if the other is also rr or is heterozygous.

during the process of dna replication, brdu can replace thymidine and incorporate into the newly synthesized dna, cell proliferation thus can be reflected in the extent of brdu incorporation.
