Answer:
D. some of the offspring are resistant and some of the offspring are susceptible to arthritis.
Step-by-step explanation:
option d. Some of the babies are resistant, and some can get arthritis.
| A | a |
------------------------
A | AA | Aa |
------------------------
a | Aa | aa |
25% chance of being homozygous dominant (AA),
50% chance of being heterozygous (Aa)
25% chance of being homozygous recessive (aa)
1. Genes decide if mice can resist or get arthritis.
2. There are two types of genes for arthritis: one for resistance (a) and one for susceptibility (A).
3. The gene for resistance (a) is weaker and gets hidden by the gene for susceptibility (A).
4. When two mice with a mix of both genes (Aa) have babies, we can check if the genes separated during the baby-making.
5. Which of the following results would show that the genes separated during baby-making?
option a. All the babies get arthritis.
option b. All the babies have a mix of the genes (Aa).
option c. Some of the babies who can get arthritis have a mix of the genes (Aa)
There are 2 types of genes that help mice be resistant or susceptible to arthritis.
The gene for being resistant to arthritis is called "a".
The gene for being susceptible to arthritis is called "A".
"A" is stronger than "a".
If 2 mice with the gene "Aa" have babies, the babies can have 3 types of genes:
* "AA" (resistant)
* "Aa" (resistant)
* "aa" (susceptible)
There are 2 genes for arthritis.
One gene makes mice resistant.
The other gene makes mice susceptible.
The resistant gene is stronger.
If 2 mice with the resistant gene have babies, the babies can have 3 types of genes:
* Resistant
* Resistant
* Susceptible
1. There are 2 genes for arthritis.
2. One gene makes mice resistant.
3. The other gene makes mice susceptible.
4. The resistant gene is stronger.
5. If 2 mice with the resistant gene have babies, the babies can have 3 types of genes:
* Resistant
* Resistant
* Susceptible
When 2 mice with the resistant gene for arthritis have babies, the babies can have 3 types of genes: resistant, resistant, or susceptible.
The following results would provide evidence that the parent alleles segregated during reproduction:
* Some of the offspring are resistant and some of the offspring are susceptible.
* Some of the offspring have the resistant gene (a) and some of the offspring have the susceptible gene (A).
* Some of the offspring are heterozygous (Aa) and some of the offspring are homozygous (AA or aa).
