Biology Flashcard on Genetic Information Transfer

Front

What do organisms transfer to their offspring?

Back

Their genetic information

Front

A young goat has downward-curved horns. Its father has upward curved horns while its mother has downward-curved horns. Which of these statements explains why the young goat has downward-curved horns?

Back

The young goat inherited its copies of the gene for horn shape from its mother and not from its father. So just like its mother's genes, it has downward-curved horns.

Sh'qira reads an article about a family of wildcats. One of them had a mutation for tooth sharpness. Which of these statements about the wildcat with the mutation is true? There must have been a change in the wildcat’s genes. The wildcat must have sharper teeth. There will be no change to the wildcat’s teeth. The wildcat must have less sharp teeth.

Back

There must have been a change in the wildcat’s genes.

Front

How does the difference in gene copies between two wolves affect the types of proteins in their tooth cells? Wolf 1 has different gene copies, while Wolf 2 has the same gene copies.

Back

Wolf 1 has two types of protein for the tooth size feature. Wolf 2 has one type of protein for the tooth size feature.

The diagram below represents the results of a cross between a pure dominant tall corn plant (TT) and a pure recessive short corn plant (tt). Which result should be expected if 100 offspring are produced?

Back

50 tall and 50 short

Each body cell of a goldfish contains 94 chromosomes. How many chromosomes are contained in a goldfish sex cell?

Back

47

The sudden appearance of a guinea pig with white fur in a population of guinea pigs that all have black fur may be the result of: ozone depletion, asexual reproduction, gene mutation, habitat destruction.
