each the top of the hill some of them are almost out of breath, while others don't even make it to the top of the hill. Only a few seem not to be affected much by the climb. Plan and design an experiment in which you offer a possible explanation for the differences in breathing rate.

Answer:

It depends on the stamina of the individual.

Explanation:

The possible explanation for the differences in breathing rate is related to the daily activities of the individuals. For example, if the daily activities of the people are hard so it has big stamina and experience no difficulty in the climbing of a hill while those people who has little hard daily activities have low stamina and their breathing rates increases while climbing a hill. Where as those people who perform no daily activities have no stamina and will be unable to climb on the hill.

What is the probability of a dominant offspring for these two parents?
marta [7]

Answer:

<em>Here we see that there are three ways for an offspring to exhibit a dominant trait and one way for recessive. This means that there is a 75% probability that an offspring will have the dominant trait and a 25% probability that an offspring will have a recessive trait.</em>

In humans having a wide jaw (W) is completely dominant to having a narrow jaw (w). Having large teeth (L) is completely dominant
Orlov [11]

Answer: The man's genotype is WwLt while the woman's genotype is wwLt.

Explanation: From the information given above, W is the allele for wide jaw, w is the allele for narrow jaw, W is completely dominant to w, L is the allele for large teeth while t is the allele for small teeth.

The man has wide jaw but his mother has a narrow jaw, since narrow jaw is recessive the man must have inherited one recessive allele for narrow jaw from his mother who has two recessive alleles for narrow jaw. Therefore since the man has wide jaw, he must be heterozygous for wide jaw (having one dominant allele for wide jaw and one recessive allele for narrow jaw), his genotype for wide jaw is therefore Ww. The man is heterozygous for teeth size, this means that he has one dominant allele for large teeth and one recessive allele for small teeth. His genotype for teeth size is Lt. Therefore the man's genotype is WwLt.

The woman has a narrow jaw, this means that she has two recessive alleles for narrow jaw (ww) and she is heterozygous for large teeth size, this means that she has one dominant allele for large teeth and one recessive allele for small teeth (Lt). Therefore, the woman's genotype is wwLt.
