Answer:

EeWw

Explanation:

The allele for the earlobe is depicted as e while that of the hairline is w.

A parent that is homzygous recessive for earlobes (ee) and homzygous dominant for hairline (WW) would have the genotype eeWW.

The other parent that is homzygous dominant for unattached earlobes and homzygous recessive for hairline would have the genotype EEww

eeWW x EEww

During meiosis, each genotype will form gametes.

eeWW: eW, eW, eW, eW

EEww: Ew, Ew, Ew, Ew

These gametes will randomly unite during fertilization to produce offspring. Since the same gametes are formed by each parent:

eW x Ew

<u>offspring</u>

100% EeWw (see the attached image for the Punnet's square)

<em>The genotype of all the children would be EeWw and would phenotypically be with unattached earlobes and dominant hairline. </em>

10. In which phase will crossing-over occur?

maxonik [38]

Answer:

C. Prohase 1

Explanation:

It is during prophase 1 of meiosis that crossing over occurs before tetrads or homologues pair of chromosomes are alligned across the equator of metaphase 1. In Meiosis 11, only the sister chromatics will be left or remain and the homologues pair of chromosomes would be moved to separate cells.

Which of the following best describes the relationship between the sun and Jupiter?

Softa [21]

Answer: B) Jupiter and the sun have a similar composition.

Explanation:The only significant difference between the sun and Jupiter is in the sizes i.e jupiter is smaller compared to the size of the sun.

However their similarities is in their composition i.e what they are made up (helium and hydrogen).

The core of Jupiter is made up of liquid metallic hydrogen and the sun's core or center is also made up 34% mass plasma of hydrogen.

So option B (Jupiter and the sun have a similar composition) best describes the relationship between Jupiter and the sun.

Describe what homologous structures are and give an example.

Juliette [100K]

A homologous structure is a structure or organ that can be found on many different animals that suggest that there is a common ancestor. It can be anywhere from a bone to a flap of skin to an organ. A common one to look at is the similarity between a human hand, bat’s wing, whale anterior flipper, and a cat’s paw. All of these have a common, 5-point structure to the bones which suggests that we all come from an animal that had 5 fingers.
