Answer:
e. Red segregated from brown in meiosis I, and straight segregated from curled in meiosis I.
Explanation:
A cross between two flies heterozygous for both genes produced an offspring with the phenotypic ratio of 9:3:3:1. This ratio is expected according to Mendel's law of independent assortment, which states that alleles of the same gene assort independently during gamete formation.
Before meiosis starts in flies, a single diploid cell duplicates its DNA, so each chromosome has 2 sister chromatids that contain the same information.
- During meiosis I, <u>the homologous chromosomes separate</u> into two daughter cells. The chromosome number is reduced by half, but each chromosome has two sister chromatids.
- During meiosis II, <u>the sister chromatids separate</u> and each daughter cell from meiosis I divides into two new daughter cells (to get the total of 4 haploid cells).
In a heterozygous fly, each homologous chromosome contains a different allele, and the sister chromatids are copies that carry the same allele. For that reason, both traits were segregated during meiosis I.
The right answer is Child abuse.
Cannabis (marijuana) during pregnancy is dangerous for the fetus
During pregnancy, the active component of cannabis, which is THC (tetrahydrocannabinol), can go into the placenta and affect the fetus, including its birth weight (like the case in the question here) and brain function, reducing the baby's IQ and attention capacity.
Depending on the type of drug and the quantity consumed, it is also possible that the baby suffers from weaning at birth, that is to say from deprivation (inconsolable crying, irritability, tremors, feeding difficulties, etc.). .
Cannabis may also have longer-term effects in children (learning disabilities, behavioral problems, hyperactivity, etc.).
