Ground my dude! wanna know how I know! I checked the other answers on the other one :)
Answer:
This question lacks options, the options are:
A. Only recessive alleles are inherited from homozygous parents.
B. Dominant alleles grow weaker as they are passed from parents to offspring.
C. Only the parent with a dominant allele can pass that allele to offspring in sexual reproduction.
D. A heterozygous parent has an equal chance of passing either the dominant allele or the recessive allele to offspring.
The answer is D
Explanation:
This question involves a single gene coding for hair length in dogs. The allele for short hair (S) is dominant over the allele for long hair (s). This means that allele 'S' will always mask the phenotypic expression of allele 's' in a heterozygous state.
According to the question, two heterozygous dogs (Ss) were crossed to produce 6 shortt-haired offsprings and 2 long-haired offsprings. An heterozygous organism is that which contains two different alleles for a particular gene i.e. a combination of dominant and recessive alleles.
Based on this, during meiosis or gamete formation, an heterozygous dog (Ss) will produce gametes with the short hair allele (S) and long hair allele (s) in equal proportion i.e. 50-50. When the two gametes containing the recessive alleles (s) produced by each heterozygous parent fuses, an offspring with a recessive phenotype (long hair, ss) is produced.
Hence, a long-hair
phenotype can appear in the offspring of two short-haired dogs because a heterozygous parent has equal chance of passing either the dominant or recessive allele to the offspring.

The complete question is as follows:
If a researcher only wanted to examine the relationship between exercise and grade point average, _________ would be used to test the variables.
A. correlation analysis
B. regression
C. hypothesis
D. central tendency measures
Answer:
The correct answer would be - A. correlation analysis.
Explanation:
To find the relationship between two variables the correlation analysis is the statistical method is used. It is used to find the what and how the one variable is related to the other variable in this method.
It is used to evaluate the relationship between any two quantitative variables.To examine the relationship between exercise and grade point average,b this method would be best as it also shows how strong is the relationship of variables.
