Answer Following General Biology Questions Flashcards

Gregor Mendel's work was different from that of other researchers working on inheritance in his day because he alone:

If several traits are affected by the same allele, the allele is said to be:

Foxes, cats, and rabbits have enzymes that are heat-sensitive, causing a seasonal variation in coat color due to:

The diploid number of chromosomes in pea plants is 14. What is the haploid chromosome number?

Human height shows a continuous variation from the very short to the very tall. Height is most likely controlled by:

White flower color is
recessive to purple. What is the genotypic ratio when two heterozygous pea
plants are crossed?

Red-green colorblindness is a sex-linked trait. A woman with
  normal color vision, whose father was colorblind, mates with a colorblind man. What chance do each of their sons have of being colorblind?


 


 
  

What is the probability of getting a pea plant with recessive green seed color when two heterozygous pea plants, both having the dominant yellow-seeded phenotype, are crossed with each
other?

Humans who have lost one
copy of a chromosome are called ____________ and generally do not survive
development

Nondisjunction of
chromosomes resulting in aneuploidy occurs during:

Mendel tested for
heterozygotes by using:

The degree of earlobe attachment in humans is  inherited as a simple dominant of free earlobes, or as a recessive allele of attached earlobes. What is the probability that a woman
with attached earlobes will have children with attached earlobes if their father has free earlobes, but his father had attached earlobes?

Genes for sex-linked traits
tend to be carried on what chromosomes?
