Answer these questions and look through the screenshots to answer the questions correctly. the images that correspond to certain questions are labeled for that question. not all questions have images-
MENDEL’S RULES OF INHERITANCE
1)For a homozygous BB parent, what percentage of their gametes will contain the B allele?
2)If we changed this Punnett square to represent a cross between an AA individual and an Aa individual, what is the chance that their offspring would have CF? (corresponding screenshot is attached)
3)The independent assortment of chromosomes happens during: A. meiosis 1, B. mitosis, C. meiosis 2
4)How many different types of gametes (i.e. different combinations of alleles) could an AADd individual produce?
SEX LINKED INHERITANCE –
5)Which of the following best explains why are there so few genes on the Y chromosome? (corresponding screenshot is attached)
6) What is the likelihood that a female offspring from this pair will have the baldness phenotype? A. 0%, B. 25%, C. 50%, D. 75%, E. 100%
7) If a genetically female individual has the recessive phenotype for a sex-linked trait, what can we conclude about her biological mother? (corresponding screenshot is attached)
DNA REPLICATION-
8)If we have one strand of DNA with a base sequence of CCGATA, what will the sequence on the complimentary strand be?
9)If you start with a single molecule of DNA, in Round 4 of PCR, how many of the product DNA molecules are going to contain a strand from the original molecule?
10)In the picture above, the samples were loaded into the wells at the top indicated by the black arrow. “bp” stands for base pairs – the number of nucleotides in a given fragment of DNA. The DNA molecule is negatively charged. Was the negative electrode placed at the bottom or the top of this gel? (See corresponding attachment image
