Answer:

3/8

Explanation:

Martha has a widow's peak (dominant trait) and attached earlobes (recessive trait).

Martha's dad had a straight hairline (ww) and unattached earlobes (Ee, because she has the recessive alleles ee and both parents give us one allele).

This tells you that martha has a mother with at least one of both alleles dominant for widow peak and at least one recesive allele of attached earlobes

So, martha's alleles are: Ww and ee.

If she marries a man that is heterozygous for both traits (Ww and Ee) the probabilitys are

Ww Ee x Ww ee: WWEe, WwEe, wWee, and wwee

How can karyotype analysis explain genetic disorders lab 15 2 answers?
damaskus [11]

A karyotype is a picture in which the chromosomes of a cell have been stained so that the banding patterns of the chromosomes appear. This way it is possible to view abnormalities in the chromosomes. Disorders such as aneuploidy can be diagnosed by karyotype. It can also help identify local abnormalities on chromosomes such as abnormalities in chromosome length,  and location of the centromere.

Afina-wow [57]

Answer:

B)Photosynthesis releases oxygen into the atmosphere while aerobic respiration removes oxygen from the atmosphere.

Explanation:

Only option B satisfies the answer to the question.

We know that photosynthesis is the process whereby green plants manufacture their foods in the presence of carbon dioxide and sunlight. Carbondioxie in the environment is used to manufacture food in plants. The bye product of photosynthesis is oxygen gas. Oxygen gas is used for aerobic respiration in animals and is essential for their life. This way photosynthesis adds to the pool of oxygen in the atmosphere and aerobic respiration removes from the pool.
