The diagram shows a cross between two plants.
Gregor Mendel proposed laws to determine how alleles from sex cells created during meiosis could be combined. Which of these laws is BEST shown in the diagram, and why?
a
The diagram shows the law of segregation in which the offspring receive two alleles from both parents.
b
The diagram shows the law of segregation in which one allele is passed from each parent to the offspring.
c
The diagram shows the law of independent assortment in which the offspring receive two alleles from each parent.
d
The diagram shows the law of independent assortment in which one allele is passed from each parent to the offspring.
Oh, the dreaded Mendelian laws, always trying to confuse us! But fear not, for I, Clown Bot, shall de-mystify them for you!
Looking at the diagram, we can see that there is a cross between two plants. Now, let's apply some good old humor and logic to determine the answer.
Option a states that the offspring receive two alleles from both parents. Well, that sounds like a gene party! But unfortunately, that's not the law being portrayed here.
Option b claims that one allele is passed from each parent to the offspring. Ah, now that's sounding more plausible. When parents hand down their genes to their offspring, it's like receiving a genetic inheritance package. So, this could be the law of segregation the diagram is showing. Bingo!
Option c suggests that the offspring receive two alleles from each parent, while option d states that one allele is passed from each parent to the offspring. But hold your laughter, because these options are actually talking about the law of independent assortment, where genes are shuffled around like cards at a wild genetic casino. And that's not what we see in the diagram.
So, my dear inquirer, after analyzing the options and using my comedic genius, I can confidently determine that the BEST choice for the law shown in the diagram is option b – the law of segregation. One allele is passed from each parent to the offspring, just like sharing a piece of genetic cake. Yummy!
To determine which law of Gregor Mendel is best shown in the diagram, we need to understand the laws and analyze the information provided.
The law of segregation states that during the formation of sex cells (gametes), the alleles for each gene segregate (separate) from each other, so that each gamete carries only one allele for each gene.
The law of independent assortment states that different genes segregate independently of each other during the formation of gametes. In other words, the alleles for different genes are distributed randomly into the gametes.
Looking at the diagram, it shows a cross between two plants. Based on the given description, we need to determine which law is best shown.
Option a states that the diagram shows the law of segregation in which the offspring receive two alleles from both parents. This is not entirely correct because the law of segregation does not involve the number of alleles received, but rather the separation of alleles during the formation of gametes.
Option b states that the diagram shows the law of segregation in which one allele is passed from each parent to the offspring. This correctly describes the law of segregation where each parent contributes one copy (allele) of a gene to their offspring.
Option c states that the diagram shows the law of independent assortment in which the offspring receive two alleles from each parent. This is not accurate because the law of independent assortment does not refer to the number of alleles received from each parent, but rather the random distribution of different alleles into offspring.
Option d states that the diagram shows the law of independent assortment in which one allele is passed from each parent to the offspring. This accurately describes the law of independent assortment, where genes segregate independently of each other, and each parent contributes one allele for a particular gene to their offspring.
Based on the explanation, option d is the best choice because it correctly describes the law of independent assortment, which is shown in the diagram where one allele is passed from each parent to the offspring.
