Why were heterozygous individuals called carriers for non-sex-linked and x-linked recessive patterns of inheritance?
I don't know and don't care
In humans straight toes S is dominant over curled toes s What would be the result of a cross between a recessive male and a heterozygous female?
The resulting offspring will have 50% chance of having straight toes and being heterozygous, and 50% chance of having curled toes and being recessive.
If 675 plants resulting from the cross display a trait controlled by a dominant allele how many plants will show the trait controlled by the recessive allele?
In a gene loci there can be four combinations of 2 alleles. Suppose these possible allele combinations are called D for dominant and R for Recessive. The possible combinations for two of them are DD, DR, RD and RR. Wherever the D occurs the dominant trait will be displayed. There is only 1 where the recessive trait is displayed and this is the last or RR case. There must be 3 times the number of cases of the dominant trait as the recessive so the recessive trait is displayed in 675 / 3 cases or 225
How can a lethal gene be passed from one generation to the other?
If the lethal gene is recessive, and the parent carrying it is heterozygous for that gene, it can be passed down to offspring in the recessive form. If the mate of the parent happens to be carrying the same gene heterozygously, 50% of offspring will be expected to inherit the recessive lethal gene heterozygously. 25% of the offspring will be expected to inherit the lethal gene homozygously, leading to death. The remaining 25% of offspring we will expect to homozygously inherit the non-lethal gene. 1:2:1 ratio
In your own words what does the term recessive trait mean?
A recessive trait is the opposite of a dominant trait. A dominant trait is the trait that overpowers another trait- represented by a capital letter. The recessive trait is the trait that is weaker, and being overpowered- represented by a lowercase letter. For example, if one person had a recessive trait for detached earlobes, it would be represented as " aa ",. If someone had a dominant trait for attached earlobes (meaning they had free earlobes), it would be represented as "AA"or " Aa "
The condition that result when excessive sodium creates a fluid imbalance with resulting bloating of the body is known as?
Hypernatremic hypervolemia.

What is the chief motives of labor?
Production, resulting in wages and, in turn, food.
How does a dominant form of an allele affect the expressions of a recessive form of an allele?
If you have a heterozygous (one dominant and one recessive) individual, it will only express the dominant allele in complete dominance; if it's codominance then some sort of "combined property" resulting from both the dominant and recessive allele would be expressed. On the other hand if you have a homozygous (both dominant or both recessive) you needn't bother.
What occurs in patients where aldosterone is lacking?
a lack of aldosterone is lethal due to electrolyte imbalance and resulting in hypotension and cardiac failure.deficiency occur in condition like addisons disease
The probability of a homozygous recessive offspring resulting from a cross between two homozygous dominant individual is?
It depends on the parents. The parent could have two dominant genes which would give a 0% chance of the offspring being recessive. The only way that the offspring could have a recessive characteristic is if the both parents have one dominant and one recessive gene, a 25% chance. The chance that both parents would pass on the recessive gene (if they have one dominant and recessive gene) is also 25%, because there is a 50% chance for each parent.
Does temperature affects genotype of Siamese cats resulting in areas of pigment of different colors?
Temperature affects the C gene codes for the enzyme tyrosinase, the first step in pigment production. The recessive alleles determine whether a cat is a complete albino or a temperature sensitive albino. These genes affect the color of the cats eyes and coat.
What will be the resulting phenotype of two alleles one being dominant to the other recessive allele?
The phenotypic ration in F1 generation will be 3 : 1. Three individuals showing dominant trait and one individual with recessive trait. However, the genotypic ratio will be 1:2:1.That is one homozygous dominant, two heterozygous dominant and one homozygous recessive individuals.
Is inherited autosomal recessive disorder in which a person lacks the enzyme that is necessary to break down a certain lipid in the brain resulting to brain damage?
Tay Sachs Disease
Labor Efficiency Variance resulting from the use of poor quality materials should be charged to?
the production manager
How do diary farmers use breeding to increase milk production?
By selecting cows that have the best milk production in the herd and breeding them to bulls whose dams also had superior milk production, resulting in heifers with higher milk production than their dams.
In humans straight toes S is dominant over curled toes s What would be the result of a cross between a recessive male and a heterozygous female?
The resulting offspring will have 50% chance of having straight toes and being heterozygous, and 50% chance of having curled toes and being recessive.
