In a plant species, the allele for dark green leaves (D) is dominant over the allele for light green leaves (d). A plant with Genotype (Dd) is crossed with a plant with genotype (did). What percentage of the offspring are expected to be hybrid for the leaf color trait. A 0% B 25%. C.50%. D 75%
Answers
So, as we set the punnet square. We get (2)Dd and (2)dd. So 100/2 = 50%.
Correct choice - C 50%.
The percentage of the offspring that is expected to be hybrid for the leaf color trait is 50%. The correct option is C.
What are alleles?The trait is caused by a pair of two alleles on the chromosome, and there are two possible outcomes. The dominant allele, which is typically written in capital letters and will control the organism's phenotype even in the presence of the other allele, is the one that has the ability to silence the other allele.
It is used in biology to refer to inherited traits that do not manifest in the phenotype of the individual who possesses them but may do so in their offspring.
Recessive alleles, which are only expressed when they are homozygous, are this other type of allele. Both heterozygous and homozygous genotypes exhibit the dominant allele.
Dd is crossed by dd.
100 / 2 = 50%.
Therefore, the correct option is C.

In the laboratory, yeast cells are usually grown at a temperature of 25oC. A scientist wanted to determine if yeast cells would reproduce faster or slower when the temperature was dropped to 15oC. The same number of yeast cells were placed in the same medium with the same amount of nutrients. One sample was kept at 25oC and the other one was kept at 15oC. The number of yeast cells was counted every hour for an eighteen hour period.
Answers
Answer:
This question is incomplete, however, it is asking to identify the following variables:
Independent variable: Temperature
Dependent variable: Number of yeast cells
Constants: same amount of nutrients, same number of yeast cells, same medium
Explanation:
- Independent variable is the variable that the experimenter changes or manipulates in order to bring about a measurable effect. In this experiment, the TEMPERATURE at which the yeast are kept is the independent variable.
- Dependent variable is the variable that responds to the changes made to the independent variable. It is the variable that is measured by the experimenter in the experiment. In this case, The NUMBER OF YEAST CELLS was counted, hence, it is the dependent variable.
- Constants are variables that are kept unchanged or same for all groups by the experimenter in order not to influence the experiment's outcome. In this case, the CONSTANTS are: same amount of nutrients, same number of yeast cells, same medium etc.

Answers
Answer:
See the answer below
Explanation:
The control group in an experimental study is the subject group that is not administered the treatment variable. The control group forms the baseline for comparing the effects produced by the treatment variable on the experimental group.
Thus, in this case, the control group would be the 10 mice that were not exposed to the radio waves.
The independent or the manipulated variable, in this case, is the exposure or otherwise of the mice to the radio waves.
The dependent variable is the actual variable that is going to be measured, otherwise known as the effect variable. In this case, the dependent variable would be the strength of the mice measured by their ability to push the block of wood blocking their food.
Since 8 out 10 mice and 7 out of 10 mice were able to push the wooden block in both the experimental and the control group, Bart's conclusion should reject the hypothesis that the radio waves make mice extra strong.
Bart's experiment can be improved by increasing the number of subject mice in each group. The more the number of subjects, the more the accuracy of the outcome would be.

In silkworms,yellow cocoon (B) is dominat over white cocoon(b). If the mom is BB and the dad is bb, what are the chances they have offspring with yellow cocoons?
Answers
Answer:
100 %
Explanation:
Dominance is a genetic phenomenon where a gene variant or allele masks the effects of another allele (of the same gene) in heterozygous individuals. This last gene variant is referred to as the recessive allele. In this case, the silkworm mother can produce only one type of gamete carrying the dominant gene (B) form, while the silkworm father can produce only one type of gamete carrying the recessive gene (b) form. In consequence, from this cross, all offspring (100 %) will be heterozygous (Bb) and therefore they will express the dominant trait (i.e., yellow cocoon).
