Cross a female with normal color vision, but whose father was colorblind, with a man who has colorblindness. Tell the expected phenotypic ratio of the offspring
Answers
If a female with normal colour vision, but her father was colour blind crosses with the man who has colourblindness, the phenotypic ratio of the offspring is 50%.
What is Colorblindness?Colour blindness is linked to the X-chromosome defect. It is a condition in which a person is unable to see the colors or differences in colours or its abilities decreased. For example, he was unable to distinguish between the colour of traffic lights, colour of fruits or choosing clothes.
Colour blindness is to be present on all X chromosome within the individual have to be affected; so the man has only one X-chromosome and women have two, the chances of colour blindness is much more higher in men as compared to women.
In the above example due to genetic inheritance of the mother from her father, the chances of colour blindness in their child is 50% because each parent is a carrier having X chromosome.
In this case chances of inheriting colour blind X chromosome would be double as likely for female child because both mother and father are the carriers of X chromosome of colour blindness.
Thus, if a female with normal colour vision, but her father was colour blind crosses with the man who has colourblindness, the phenotypic ratio of the offspring is 50%.

Answers
The expression of certain genes at different levels may cause color variation in the butterfly wings.
What is gene expression?Gene expression is the cellular process associated with the transcription of certain genes in particular cell types.
In this case, the trait color in butterfly wings is associated with the differential expression of certain genes during development.
The variation in color may be due to the expression of different alleles in butterflies or the same allele at different levels.

Answers
Polygenic inheritance occurs when a trait is controlled by several pairs of genes, traits such as skin color and height in humans are the result of it.
What is polygenic inheritance?It is used to refer to the inheritance of quantitative traits that occurs when a character is due to the action of more than one gene that may also have more than two alleles.
That is, it occurs when a characteristic is governed by two or more sets of alleles, there are traits, such as weight, skin color, height, which are governed by the cumulative effect of many genes.
Therefore, we can conclude that polygenic inheritance occurs when a trait is controlled by several pairs of genes, traits such as skin color and height in humans are the result of it.

The data in the graph are the result of a paramecium being placed in a hypertonic salt solution.
A graph entitled Paramecium Contractile Vacuole Contractions has salt concentration on the horizontal axis and contractions per minute on the vertical axis. A very low salt concentration has 30 contractions per minute, low: 22, medium: 15, high: 8, very-high: 2.
Based on the data in the graph, which would most likely happen if the paramecium were placed in distilled water?
The contractions would increase.
The contractions would decrease.
The contractions would cease altogether.
The contractions would establish dynamic equilibrium.
Answers
Based on the data in the graph, the condition that would most likely happen if the paramecium were placed in distilled water is the contractions would increase.
What do you mean by Hypertonic salt solution?The Hypertonic salt solution may be defined as a solution that consists of a higher concentration of solute particles outside a membrane as compared to inside.
The contraction would increase when the paramecium was placed in distilled water because as the osmolarity of the distilled water decreases, the contraction would increase. Due to the hypotonic nature of distilled water, the contraction of the contractile vacuole of the paramecium will increase and expel more water quickly.
Therefore, based on the data in the graph, the condition that would most likely happen if the paramecium were placed in distilled water is the contractions would increase.
