A= pigment
emmainna [20.7K]

Here you have two characteristics to cross on Punnet square: Blood type and pigment.

They told you both parents are AB this means co-dominance of A and B, you draw the Punnett square (photo), and you'll see your offspring possibilities are 50% AB type, 25% A type, and 25% B type.

Now they told you both parents are homozygous for pigments this means Aa. When you draw the Punnett square (photo), you'll see your offspring possibilities are 50% Aa, 25% AA, and 25% aa.

75% pigmented and 25% albino.

For each population description, identify which Hardy-Weinberg assumption is violated?
zavuch27 [327]

Answer:

4. A large and isolated population of squirrels in a relatively stable environment in which no genetic mutations are occurring and mating between males and females is random.

Explanation:

1. A small and isolated population of seals living in a stable environment with no genetic mutations.❌

1. false

Hardy-Weinberg assumption is not violated for a small population as seen in this case.

2. A large population of fish where females mate with males based on size.❌

false

Hardy-Weinberg assumption is not violated for an instance where mating is not random as seen in this scenario.

3. A population of birds with no genetic mutations that often mate with members of neighboring bird populations.❌

False

Hardy-Weinberg assumption is not violated for where gene flow is seen among population in this scenario.

4. A large and isolated population of squirrels in a relatively stable environment in which no genetic mutations are occurring and mating between males and females is random.✔

True

Hardy-Weinberg assumption is violated for in this situation due to large population size.

5. A small population of spiders living in an environment that strongly favors larger individuals.❌

false

Hardy-Weinberg assumption is violated for a small population and natural selection occurring as its obvious in this case.

There are five primary Hardy-Weinberg assumptions:

A. no mutation,

B. random mating,

C. No gene flow,

D. infinite population size,

E. No selection.

If the assumptions are exempted in a gene, the population of that gene might undergo evolution causing a resultant change in the gene's allele frequencies.

How does an inhaler work?
ryzh [129]

Answer:It works by relaxing the muscles of the airways into the lungs, which makes it easier to breathe. Salbutamol comes in an inhaler (puffer). Salbutamol inhalers are usually blue. Salbutamol is sometimes given as tablets, capsules or syrup for people who cannot use an inhaler very well.
