Answer:

Correct

Explanation:

When combining more than two circles in a Venn diagram you have to actually mix in the colors where the intersections are so that you will be able to tell their differences.

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:

<u>Available data</u>:

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

pychu [463]

<h2>Endothermic Process</h2>

Explanation:

An example of endothermic process is :

Heat is needed for water to boil.

Endothermic process can be defined as a process in which heat energy is absorbed from the surrounding that bring about changes in the molecular level like breaking chemical bonds, inter-molecular force of attraction etc.

Boiling of water is an endothermic process because during this process water absorbs heat , its kinetic energy increases and then it boils.

Question 37 (2 points) Saved

Veronika [31]

Answer: The non-vascular plant group are

A) Chlorophytes

B) Charophytes

C) Bryophytes

Explanation:

Charophytes, Chlorophytes and

Bryophytes are those plants having multicellular body and doesn't have a vascular bundle i. e. xylum and phloem. In vascular plants, xylum ia is responsible for the transportation of water and phloem is responsible for the transportation of food materials from one part to another. These bundles are absent in Chlorophytes, Charophytes and Bryophytes.
