Answer: 1/16, or approximately 6.25% (see explanation below)
Explanation:
Answering this question requires two steps.
First, we need to figure out the probability that this couple will have a child with albinism in the first place. We know the following:
- Both parents are unaffected.
- The couple has already had one affected child.
- Albinism follows an autosomal recessive inheritance pattern.
Let ( M = normal gene ) and ( m = mutated gene ). Since the condition is recessive, the affected child can be assumed to have a “mm” genotype. Barring the possibility of a de novo mutation (which are assumed to be rare), the affected child must have inherited one ”m” allele from each parent. Since both of them are unaffected, however, we can assume that they are both carriers (genotype “Mm”). In conclusion, 1/4 of their offspring (25%) <em>for any given pregnancy</em> may be expected to have albinism. See the resulting Punnett square:
<u> | M | m </u>
<u>M | MM | Mm </u>
<u>m | Mm | mm </u>
Note that the question asks about the probability that not one but two consecutive births result in affected children. Since it can be assumed that both events are independent (meaning: the outcome of a pregnancy does not influence the outcome of following ones), we may apply the rule of multiplication for probabilities. The final answer is therefore 1/4 * 1/4 = 1/16.
Answer:
The correct options are: A "
vestigial wings, red eyes" and D "full wings, purple eyes"
Explanation:
female parent: vg+pr+/vg pr
(phenotype - full winged and red eyes)
male parent: vgpr/vgpr
(phenotype - vestigial winged and purple eyes)
Of these traits, vestigial wings and purple eyes are recessive traits. Hence, when a recombination event occurs, the offspring can potentially have a wild type trait paired with a recessive trait.
Answer:
<u><em>The correct option is C) Meiosis produces 4 daughter cells each with half the number of chromosomes of the original cell.</em></u>
Explanation:
There are two main processes by which cell divides:
1) Mitosis
2) Meiosis
All the cells of the body divide by the process of mitosis except the sex cells.<em> Sex cells divide by the process of meiosis.</em>
Meiosis can e described as a type of cell division in which four daughter cells are formed each having half the number of chromosomes as the parent cell. This is because the cell has to attain half of the maternal and half of the paternal chromosomes at the time of fertilization.
Crossing over and independent assortment are the phenomenon of meiosis which bring genetic diversity among parent and children.
Answer:
If i had more info, id have a better answer. But based of luck and guessing, i am going to go with c) almost 50% of the cities have an average monthly temperature less than or equal to 35 degrees C.
