According to the pedigree chart, which statement MUST be true?
dem82 [27]

Answer:

<h3>A) Only Male offspring can inherit the disease. </h3>

Explanation:

As per the pedigree chart, only the males are shown as affected by the disease. Thus, it must be a sex-chromosomal inheritance, expressed in the Y chromosome or the male chromosome.  

As the females in the family are unaffected, hence the mother in the original parental generation cannot be a carrier.

It is likely that the father from the original parental generation might be the carrier.

As there are affected individuals in both the generation after the original parental generation ( the last generation having two more affected males), the statement that the chances of inheriting the decease with each successive generation is not true.

For a gene that determines wing color in butterflies, there are three possible genotypes: BB (blue wings), bb (white wings), and
Oduvanchick [21]

Answer: The frequency of the b allele is calculated as follows: since there are 2 alleles in each organism, total number of genes is 200. The number of white alleles is 10*2+30 (since there are 2 copies of the alleles in white organisms and 1 copy of the b allele in the white wings with blue blotches). So the total number of white alleles is 20+30=50 white alleles. The frequency of the white allele is then 0.25. So the frequency of the blue allele is 1-0.25=0.75. Since heterozygous term is 2*p*q, the frequency of the Bb genotype is 2*0.25*0.75=0.375. Hope that helped!
