Describe how insulation works and the role it plays in keeping our homes at a comfortable temperature.

1 answer:

3 0

Insulation isa property of objects that inhibits heat transfer and its counter property is conduction.
As much hot air is pressured into the room space by a condiitioner, the heat accumulates. The objects we have at home like cloth, wood and other objects inhibits or gradually slows the heat to escape and going onto the cold areas outside. This prevents the room temperature from shrinking from its desired state.

What is the probability that the first offspring from the cross listed below will be heterozygous for all loci?

Tanya [424]

Answer and Explanation:

Cross: aa Bb dd Ee x AA bb Dd Ee

We can calculate the probability of getting heterozygous individuals in the progeny by using the product rule. Assuming that these four genes assort independently (events that occur independently from each other), we can infer that the F1 will have the next genotypic proportions for each gene:

1) aa x AA

F1) 4/4=1 Aa

2) Bb x bb

F1) ½ bb

½ Bb

3) dd x Dd

F1) ½ dd

½ Dd

4) Ee x Ee

F1) ¼ EE

2/4 = ½ Ee

¼ ee

So, to know what the probability is that the F1 of being heterozygous for all loci, we must multiply the respective individual probabilities of getting a heterozygous genotype, like this:

1 Aa x ½ Bb x ½ Dd x ½ Ee = 1/8 AaBbDdEe
