Answer:
a. Heterozygous individuals may pass on their copy of the disease-causing allele to offspring.
Explanation:
Tay-Sachs, which is a recessive lethal disease ---- Let say the recessive lethal diseases is s
∴ it only results when an individual posses two copies of the diseases-causing allele i.e two copies of the disease will be ss.
Now, when two hetrozygous individuals crossed , it is obvious that each can pass on their copy of the disease-causing allele to the offspring.
Let show an illustration for the above statement.
Let the heterozygous individual be Ts, if Ts cross with another Ts;
we will have:
Ts × Ts
T s
T TT Ts
s Ts ss
the offspring are TT,Ts,Ts,ss
We can now see how the Heterozygous individuals pass on their copy of the disease-causing allele to the offspring (Ts).
Answer:
The correct order is
Prophase l , Metaphase l, Anaphase I, Telophase l, Prophase ll, Metaphase II, Telophase ll / Cytokinesis ll
Explanation:
In Meiosis there are total two phases - Meiosis I and Meiosis II and each phase consists of total six sub phases which are as follows -
Meiosis I
1. Prophase I
2. Prometaphase I
3. Metaphase I
4. Anaphase I
5. Telophase I
6. Cytokinesis I
Meiosis II
1. Prophase II
2. Prometaphase II
3. Metaphase II
4. Anaphase II
5. Telophase II
6. Cytokinesis II
Hence the correct order is
Prophase l , Metaphase l, Anaphase I, Telophase l, Prophase ll, Metaphase II, Telophase ll / Cytokinesis ll
Answer:
A
Explanation:
I'm pretty sure it's A because fish = fish feces which = nutrients.
The probability of the female child of Charles and Marie suffering from hemophilia is 50% or 0.5.
<h3>What is the probability of hemophilia?</h3>
Hemophilia is a disease that is linked to the X-chromosome.
The probability of having female who suffers from hemophilia depends on the genotype of the parents.
Assuming that the genotype of the parents are as follows:
Father: XcY --> hemophilic
Mother: XXc --> carrier
A cross between the parents will produce two female offspring with genotypes, XcXc and XXc.
Therefore, the probability of the female child of Charles and Marie suffering from hemophilia is 50% or 0.5.
