Answer:
There is no image of the Karyotype but the question will be answered based on a general knowledge of gamete formation (meiosis) in human females.
Based on this, the answer is: During metaphase II of meiosis, each cell will have 23 individual chromosomes each composed of 2 chromatids
Explanation:
Meiosis is the cellular division process employed by sexually-reproducing organisms to produce gametes. It involves the production of daughter cells (gametes) that have a reduced number of chromosomes (half) as the parent cell. Since meiosis reduces the chromosomal number, it occurs in two division steps: meiosis I and II.
Meiosis I involves the separation of homologous chromosomes (similar but non-identical chromosomes received from each parent) into opposite poles of the cell. This is where the reduction takes place. Humans contain 46 chromosomes or 23 pairs of chromosomes in their somatic cells. At the end of meiosis 1, each daughter cell will contain 23 chromosomes each.
In Metaphase of meiosis II as stated in the question, each cell will contain 23 individual chromosomes. Each chromosome being a sister chromatids i.e. 2 CHROMATIDS. The sister chromatids are to be separated in the Anaphase stage of meiosis II.

please correct me if im wrong
Answer:
The correct answer is - brown heterozygous Bb and blue eye bb.
Explanation:
In the provided question it is given that there are 20 babies born, 10 babies had blue eyes and 10 had brown eyes. As it is known that brown eyes are dominant over blue eyes, therefore, on the basis of this we can say that all blue-eyed babies have a bb genotype and as brown eyes are dominant traits babies must have at least one copy of the B allele which represents brown eye trait.
case1:
Parent 1 : bb
parent 2: BB
B B
b Bb Bb
b Bb Bb
there are 100% brown eye offspring so this is not the case
case 2:
Parent 1 : bb
parent 2: Bb
B b
b Bb bb
b Bb bb
here, 50% brown eyes and 50% blue eyes offspring produced thus, the parent trait will be brown heterozygous and blue eye.
Answer:
Apoptosis (programed cell death)
Explanation:
Apoptosis is a type of controlled cell death. It happens throughout development when cells have to be removed. It also gets rid of diseased cells, such as those that are potentially cancerous, or those infected with a pathogen, for example.
