Answer:
See the answer below
Explanation:
<em>If pink eye is recessive, it means that the normal eye is the dominant trait. According to Mendelian law, the ratio of normal to pink eye in a cross involving two heterozygous mice should be 3:1</em>.
Chi-square = 
where O = observed frequency and E = expected frequency.
Phenotype Observed Expected Chi-square
Normal 18 3/4 x 20 = 15 
= 0.6
Pink 2 1/4 x 20 = 5 
= 1.8
Total Chi-square = 0.6 + 1.8 = 2.4
Degree of freedom = 2 - 1 = 1
Critical Chi-square value at 95% = 3.841
<em>The critical Chi-square value is more than the calculated value. </em><u><em>Hence, the observed number of offspring fits the expected number of offspring.</em></u>
Answer:
fertilized egg/ baby
Explanation:
Females have an egg inside of them and when fertilized by the male through the process of reproduction the egg begins to grow.
Answer:
it condenses the DNA so that it can fit inside the cell.
Explanation:
Supercoiling is a level of genome packaging and is important for the packaging of the DNA which is about 2m in length inside a nucleus that is about 6microm. Supercoiling refers to the over (positive supercoiling) or under winding (negative supercoiling) of a DNA strand, and is an expression of the strain on that strand. Supercoiling is in compacting DNA, and also allows for the regulation of access of transcriptional machinery and other biological activities to the DNA and in turn gene expression. Certain enzymes such as topoisomerases are able to change DNA topology to facilitate access of DNA replication or transcription.
