What is the genotype of the pink flowers?
Pink flowers are the results or offspring of the cross of red and white parental generation. Red flowers gentoype are generally referred to as RR, the uppercase R refers to the red pigment which is dominant over the ww, or white recessive. Using a punnett square of the RR x ww cross... RR x ww Rw Rw genotype: 1 (100%) Rw Rw Rw phenotype: 1 (100%) pink ...yields 100% pink flowers with the genotpe of Rw. An easy way to remember the difference between phenotype and genotype is that both phenotype and physical begin with ph and pehnotype refers to physical appearances/frdcriptions.
In crossing a homozygous recessive with a heterozygote what is the chance of getting a homozygous recessive phenotype in the F1 generation?
1/2 or 50%. The homozygous recessive gentoype contains two recessive alleles for the gene for a trait. So the homozygous recessive individual can pass on only recessive alleles to an offspring. The heterozygous individual has one dominant and one recessive allele for the gene for a trait. So the heterozygous individual can pass on either a dominant or a recessive allele to an offspring. So if an offspring inherits a recessive allele from the heterozygous parent, along with the recessive allele from the homozygous recessive parent, it will have the homozygous recessive genotype and phenotype.
What is the genotype of parents with type A and B blood type?
We are looking for the possible blood types of the PARENTS.Available information:Baby type A -- can be either AA or AOAt least one parent must be type A.Baby receives one gene from each parent: Mama type AA/AO + Papa AA/AO = Baby type AA, AO, OOMama type AA/AO + Papa BO = Baby type AB, AO, BO, OOMama type AA/AO + Papa AB = Baby type AA, AO, BB, BO, ABMama type AA/AO + Papa OO = Baby type AO, OOPapa cannot be Type BB as that cross would only give AB or BO results. Other than that, as long as Papa contributes an A or an O, the baby will be Type A.
Why can a man who has sex-linked disorder pass tge disorder to his daughters but not his sons?
The sex-linked traits you refer to are probably located on the X chromosome. Because all boys receive their Y chromosomes from their fathers (after all, the mother has no Y chromosome), they cannot also have received an X chromosome which might contain the sex-linked trait from their fathers.
