Suppose 36% of a remote mountain village cannot taste PTC and must, therefore, be homozygous recessive (aa) for the PTC non-tast

er allele. If this population conforms to Hardy-Weinberg expectations for this gene, what percentage of the population must be homozygous (AA) for the PTC taster allele?

Answer:

16%

Explanation:

The frequency of homozygous recessive genotype in the given population= 36% or 0.36

So, the frequency of the recessive non-taster allele in the given population would be = square root of 0.36= 0.6

Since the population is in HWE, the frequency of the dominant allele for this locus in the population= 1- frequency of the recessive allele= 1-0.6= 0.4

Therefore, the frequency of the homozygous dominant genotype in the given population = 0.4 x 0.4 = 0.16 or 16%

If the traits for white fur and red eyes were always inherited together then the hypothesis would not have been supported by the data.

Explanation:

The white fur and red eyed mouse had genotype AA RR or AaRr

The black fur mouse and black eye mouse had genotype aarr

The F1 offspring will have all offspring with same phenotype as shown in the Punett square.

                               

   AR     AR

ar AaRr  AaRr

ar AaRr  AaRr

all the siblings are of same phenotype

Punnet square to show that genes assort independently.

    Ar     AR

ar Aarr  AaRr        2 white fur and black eye: 2 white fur red eye

ar Aarr  AaRr

The phenotype pattern of this punnet square shows that white fur and red eyes are not always inherited.

The law of independent assortment is shown from the cross that is  by selfing.

         AR        Ar          aR       ar

AR  AARR  AARr    AaAR     AaRr

Ar   AARr   AArr     AaRr       Aarr

aR   AaRR  aArR     aaRR     aaRr

ar     AaRr   Aarr     aaRr      aarr

phenotype ratio of 9:3:3:1

9 WHITE FUR RED EYE

3 WHITE FUR BLACK EYE

3 BLACK FUR RED EYE.

1 BLACK FUR BLACK EYE

By cross checking, the options given it is concluded that the traits for white fur and red eyes are not always inherited together, the two traits are governed by different genes and are independently exhibited in the individual as stated in law of independent Assortment.

if a cell with 36 chromosomes undergoes mitosis, how many cells will be produced and how many chromosomes will be in each cell​
fiasKO [112]

Answer:

See explanation:

Explanation:

When a cell undergoes mitosis, it becomes two cells. If the cell has 36 chromosomes to begin with, it also has the exact same after mitosis. Each cell duplicated has the same amount. In this case, each one has 36 chromosomes.

Hope this helps!! Have an Awesome day!!! :-)
