PBSC GENES and INHERITANCE - Part 1 BSC1005 259323 CONCEPTS IN BIOLOGY

QuestionAnswer
The results of a test cross show ALL the offspring with the dominant phenotype. What is the genotype of the unknown parent? homozygous dominant
This is the term for the genetic make up of an individual. Genotype
If T stands for tall and is dominant, t is recessive and stands for short. If two heterozygotes are crossed, what are the genotypic ratios of the offspring? 25% TT, 25%tt, 50% Tt
A gene which is capable of hiding or masking a second gene is known as _____. Dominant
Genes code for _____. proteins
If T stands for tall and is dominant, t is recessive and stands for short. If two heterozygotes are crossed, what are the phenotypic ratios of the offspring? 75% Tall, 25% short
If T stands for tall and is dominant, t is recessive and stands for short. If TT is crossed with tt, what is the genotypic ratio of the offspring? 100% tall
This is the term for the physical manifestation of the genotype. Phenotype
____________ states that gene pairs are split during meiosis (only one allele can be carried in a single gamete). Law of Segregation
Test crosses are always done with a KNOWN ______ . homozygous recessive
If T stands for tall and is dominant, t is recessive and stands for short. What is the homozygous recessive genotype? tt
If T stands for tall and is dominant, t is recessive and stands for short. What is the heterozygous genotype? Tt
A gene which can be hidden or masked by another gene is considered _____. Recessive
Two genes which code for the same trait on homologous chromosomes are known as _____ _____. Gene pairs
A unit of DNA which codes for a protein. gene
What is the proper term for this genotype? tt Homozygous recessive
If T stands for tall and is dominant, t is recessive and stands for short. What is the homozygous dominant genotype? TT
What is the proper term for this genotype? TT Homozygous dominant
What is the proper term for this genotype? Tt Heterozygous
Alternative forms of the same gene are known as _____. Alleles
The results of a test cross show HALF the offspring with the dominant phenotype and HALF the offspring with the recessive phenotype. What is the genotype of the unknown parent? Heterozygous
If T stands for tall and is dominant, t is recessive and stands for short. If TT is crossed with tt, what is the phenotypic ratio of the offspring? 100% tall

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
