two parent butterflies with normal wings have offspring with altered wing shapes what most likely caused this change

Biology
1 answer:
Allisa [31]2 years ago
3 0

Answer:

The Parents may have had heterozygous genotypes.

Explanation:

Normal wings could be the dominant allele that is expressed in the phenotype, and altered wings could be the recessive allele. If both parents had a heterozygous genotype, it is possible for the offspring to have a homzygous recessive genotype.

Ket [755]

Answer:

a. Zero percent

b. Fifty percent

Explanation:

As it has been mentioned in the question that both man and woman are normally pigmented and each one have an albino parent thus both will be heterozygous and their allelic makeup will be as follows -

Man - Aa

Woman - Aa

After a cross between Aa × Aa we get the following result-

One AA, Two Aa and One aa

It is clear that only the aa type of offsprings will be albino.

Out of 4 there is probability of only one to be albino so out of two there will be 50% probability of being albino.

The probability of both sons to be albino will be zero percent.

4. The Rh blood type response system is controlled by the D allele. The genotypes DD and Dd are Rh (Rh positive); dd is Rh- (Rh
DedPeter [7]

Answer:

A - Frequency of D allele = 0.35

Frequency of d allele = 0.65

B- Frequency of DD genotype = 0.1225

Frequency of Dd genotype = 0.455

Frequency of dd genotype = 0.425.

C - Total population = 400

Frequency of heterozygous population = 400*0.455 = 183.

EXPLANATION:

The equilibrium sum of all the allelic frequency of a gene is always 1 and sum of all the genotypic frequency of all the genotype is always 1 - This is according to Hardy-Weinberg.

So p+q =1

p2+ 2pq+q2 =1

where p = frequency of dominant allele

q is the frequency of the recessive allele.

from the question, it was given that there were  170 individual out of 400, which were Rh- negative,

So q2 = 170/400 = 0.425

q= 0.65

Also p+q =1

so p = 1-q

or p = 1-0.65

Hence p =0.35

Frequency of homozgupus for D allele = 0.35*0.35 = 0.1225

Frequency of heterozygous or Dd will be 2pq.

or 2*0.35*0.65 = 0.455

A - Frequency of D allele = 0.35

Frequency of d allele = 0.65

B- Frequency of DD genotype = 0.1225

Frequency of Dd genotype = 0.455

Frequency of dd genotype = 0.425.

C - Total population = 400

Frequency of heterozygous population = 400*0.455 = 183.
