Albinoism is an autosomal recessive trait. What is the probability of two
1 answer:
Answer:
1. Probability is 50% or 1/2
2. a) Genotypic ratio= 1 AA: 2Aa : 1aa
b) Phenotypic ratio = 3 normal pigment : 1 albino
3. Monohybrid cross
Explanation:
This question involves a single gene coding for pigment in humans. The allele for normal pigmentation (A) is dominant over the allele for albinism (a).
According to this question, if two heterozygous parents (Aa) are crossed i.e. Aa × Aa. The following proportion of offsprings will be produced:
AA, Aa, Aa, and aa
- Hence, the probability of having a heterozygous offspring is 2/4 or 1/2 or 50%
- Genotypic ratio= 1 AA: 2Aa : 1aa
Phenotypic ratio = 3 normal pigment : 1 albino
c. This type of cross is called MONOHYBRID CROSS because it involves a single gene

Answer:
Explanation:
We are asked to find the energy given mass, specific heat, and change in temperature. Therefore, we must use this formula;
The mass is 15 grams and the specific heat is 0.129 J/(g×°C). Let's calculate the change in temperature.
- ΔT= final temperature - initial temperature
- ΔT= 85 °C- 22°C = 63°C
Now we know all the values:
Substitue the values into the formula.
Multiply the first numbers together. The grams will cancel.
Multiply again, this time the degrees Celsius cancels.
<u>121.905 Joules</u> are required.
