Answer:
Genotype of parents: Ss x ss
Genotype of offsprings: Ss ss
Expected ratio of short to long: 2 : 2 = 1 : 1
The actual ratio in this problem is Eight kittens have short hair and 3 have long hair: 8 : 3
Explanation:
In cats the allele for short hair is dominant over the allele for long hair. (SS or Ss for short hair; ss for long hair).
A short haired male and long haired female have kittens. Eight kittens have short hair and 3 have long hair.
For the parents to have been able to produce long haired offsprings, it means both parents possess one copy each of the recessive traits. Thus we have
Phenotype of parent: A short haired male and long haired female
Genotype of parents: Ss x ss
Genotype of offsprings: Ss ss
Expected ratio of short to long: 2 : 2 = 1 : 1
The actual ratio in this problem is Eight kittens have short hair and 3 have long hair: 8 : 3
Answer:
1) M1 is heterozygous since it contains 2 bands, which means that it contains one recessive and one dominant allele
P1 is homozygous for this locus, since it contains a single band or is known to be homozygous for the locus or gene.
P2 is hetozygous for this locus because two bands appear in which each band represents one allele for the gene.
ChildC contains two gel bands, representing two alleles and is therefore heterozygous
P1 is the father of the child C1, if we look at the gel, each father shows a similar band, one coinciding with the mother and the second with the father p1
As for the paternity study, the PCR test is not useful, since it provides asymmetric results, thus only one strand information will be provided, and because the DNA is double-stranded, a more complete study is required.:
Answer:
The statement which is true is as follow:
d. Two hairs from the same head may not have the same morphological characteristics.
Explanation:
- The statement in option a is not correct as we can't always determine the racial origin of hair.
- The statement in option b is not correct as it is not possible to do through trace elemental composition.
- The statement in option c is not correct as hair is not examined to determine the sex because the Shettles Method is uses to determine the sex of a baby.
- The statement d is correct as the hair have different structural features like length which makes its morphological characteristics.
