Can anyone tell me the ratio of the genotype and phenotype ???
1 answer:
<h2>Hey There!</h2><h2>_____________________________________</h2><h2>Answer:</h2><h2>_____________________________________</h2><h2>Phenotype:</h2>
It is the physical appearance of the trait, whether the person has smooth chin or cleft chin.
<h2>Genotype:</h2>A genotype refers to the genetic characteristics of an organism's trait, if it is heterozygous or hom.ozygous, recessive or dominant.
<h2>_____________________________________</h2><h2>Alleles:</h2>Cleft chin C is dominant over smooth chin c
<h2>Genotypes of Parents:</h2><h3>FATHER:</h3>Father has smooth chin thus, it is hom.ozygous recessive i.e. cc
<h3>MOTHER:</h3>Mother has cleft chin, since cleft chin is dominant there are two possibilities of her genotype,
Heterozygous Dominant : Cc
Hom.zygous Dominant : CC
but if we cross the hom.zygous fominant mother to hom.ozygous recessive father we will get all the offsprings with the same genotype phenotype so it is not possibile, So the mother is HETEROZYGOUS DOMINANT Cc
<h2>_____________________________________</h2><h2><u>Question</u>:</h2><h2>_____________________________________</h2><h2>Genotypes of Parents:</h2>FATHER: cc (Hom.ozygous Recessive)
MOTHER: Cc (Heterozygous Dominant)
<h2>_____________________________________</h2><h2>Punnet Square:</h2>Picture attached!
Picture no 1: it is the cross between hom.ozygous recessive father and hom.ozygous dominant mother and all the offsprings are same both phenotypic and genotypic way so IT IS NOT POSSIBILE
Picture no 2: Its cross between hom.ozygous recessive father and heterozygous dominant mother and there are hybrid and pure recessive both type of offsprings present thus IT IS POSSIBLE!
<h2>_____________________________________</h2><h2>Genotype Ratio of the Offspring:</h2>Hybrid : Pure Recessive
2 : 2 or 1 : 1
<h2>_____________________________________</h2><h2>Phenotype Ratio of the Offspring:</h2>Cleft Chin : Smooth Chin
2 : 2 or 1 : 1

Answer:
According to the diagram, what is occurring in step 7 is cytokinesis, with the separation of two daughter cells, following cell division.
Explanation:
Cytokinesis is a process that occurs at the end of mitosis or meiosis, being the final step of cell division. This mechanism allows the <u>separation of the two daughter cells</u>, with equal distribution of cytoplasm and formation of cell membrane, differentiating into two independent cells.
In the diagram it can be observed (step 7) that after the division process —in yellow— two arrows pointing to two cells are evident, which implies the process of cytokinesis.
Prior to the cytokinesis process, karyokinesis occurs, which is the separation of nuclei and formation of the nuclear membrane.
In animal cells, karyocinesis occurs by the effect of a ring of actin and myosin that helps to force the separation. In the plant cell, the fragmoplast is formed, a septum that induces the separation of the daughter cells.
The other options are not correct because:
- <u><em>Cell growth</em></u><em> occurs in G1 phase.</em>
- <u><em>Cell preparation</em></u><em> occurs in interphase.</em>
- <u><em>DNA replication</em></u><em> occurs in S phase.</em>
- <u><em>Mitosis</em></u><em> is represented in yellow, and involves 4 phases.</em>
