1 answer:

6 0

The answer is March and September. This period is referred to as the equinox when the sun is overhead the equator. The days and nights are equal all over the earth. June 21 and December 21, on the other hand, are the date-months when the two solstices (when the earth is at the extreme north and south latitude latitudes) occur on earth.

Complete question:

A geneticist crossed fruit flies to determine the phenotypic ratio. The geneticist crossed a fly with blistery wings and spineless bristles (bbss) with a heterozygous fly that had normal wings and normal bristles (BbSs). Which proportion of offspring that are dominant for both traits in would you not expect based on Mendel's law of independent assortment? 1/2 , 4/16, 25% , or 1/4

Answer:

1/2 is the proportion of the offspring that is NOT expected among individuals that are dominant for both traits.

4/16 = 1/4 = 25% of the progeny and the correct expected proportion of individuals that are dominant for both traits.

Explanation:

Available data:

Cross: a fly with blistery wings and spineless bristles with a heterozygous fly that had normal wings and normal bristles
Recessive trait: blistery wings and spineless bristles
Dominant trait: normal wings and normal bristles

Let us say that:

B is the dominant allele for normal wings
b is the recessive allele for blistery wings
S is the dominant allele for normal bristles
s is the recessive allele for spineless bristles

Parentals) bbss x BbSs

Gametes) bs, bs, bs, bs BS, Bs, bS, bs

Punnett square) BS Bs bS bs

bs BbSs Bbss bbSs bbss

F1) 4/16 = 1/4 = 25% of the progeny is expected to be BbSs, dyhibrid individuals, expressing normal wings and normal bristles

4/16 = 1/4 = 25% of the progeny is expected to be Bbss, expressing normal wings and spineless bristles

4/16 = 1/4 = 25% of the progeny is expected to be bbSs, expressing blistery wings and normal bristles

4/16 = 1/4 = 25% of the progeny is expected to be bbss, expressing blistery wings and spineless bristles
