Answer:
Answer is D "Genes for the two traits are located close together on the same chromosome, and crossing over occurred between the two gene loci"
Explanation:
Traits are distinguishing characteristics of an organism. The Phenotypic crossing of the Drosophila melanogaster specie with Gray body and long wings over that of the same specie but female with black body and apterous wings produced a total of 100 offspring, which showed a that genetic crossing were done on the closely related chromosomes of the body traits for the individual species.
Answer:
We use pH as a measurement of how acidic something is. pH scale is what we use to determine how acidic it is. i tried hope it helps:)
Explanation:
The nurse could find an 86-106 systolic and 42-63 diastolic pressure in toddlers. Though taking a toddler's blood pressure is infinitely harder compared to adults, their blood pressure is often influenced by many factors because they are growing up. Generally, boys' blood pressure will be higher than the girls'. Those taller kids will have a more normal blood pressure than the shorter ones. Age and sex affect the blood pressure of toddlers.
Unlike natural selection, genetic drift does not depend on an allele's beneficial or harmful effects. Instead, drift changes allele frequencies purely by chance, as random subsets of individuals (and the gametes of those individuals) are sampled to produce the next generation.
