The Answer To This Question Is C.
Answer:
1) Firstly, lets sort out the alleles for the dominant and recessive characteristics. The dominant brown allele will be written as B and the recessive red hair allele will be written as b.
2) Lets sort out the genotype of the parents. The parent having homozygous brown coloured hair will carry the alleles BB. The parent carrying the heterozygous brown coloured hair will carry the alleles Bb.
3) The punnet square from these parents will be drawn as follows:
B b
B BB Bb
B BB Bb
4) Now, lets predict the phenotype of the offsprings. The results from the punnet square show that all of the offsprings will have brown coloured hair.
5) The genotype for the children will have 50% chance to be homozygous brown (BB) and 50% chance to be heterozygous brown (Bb).
Answer:
No lactose individuals have two biological parents that are lactose intolerant
Explanation:
In this case lactose intolerance would be coded for a recessive gene (r). if both parents are lactose intolerant the would both be the genotype (rr) . For individual to be lactose intolerant atleast one parent most be lactose tolerant posesing the dominant (R) gene. Which both parents in this example lack.
D. 1,200
This is because if it takes 1 and a half hours **1.5** to travel through city a and city b , and the plane goes 800km per hour and 400km is half of that it then the answer has to be d.
