Hi The cells after the metaphase I am with the equal distribution of the chromosomes; the statement now asks that chromosomes arrangement in the cell is by the given eight variations. You have to sort the cell accordingly in the meiosis II distr
Meiosis (3 of 3): Determinants of Heredity and Genetic Variation (BioFlix tutori
Part A - Independent assortment and genetic variation Consider a diploid cell where 2n = 6. During metaphase I of meiosis, as the pairs of homologous chromosomes line up on the metaphase plate, each pair may orient with its maternal or paternal

In a certain breed of chicken, an incomplete dominant gene controls color. The homozygous black, when crossed with the homozygous splashedwhite, produces an intermediate gray color pattern referred to as blue. A second gen
Four new students are learning how to count bacteria colonies. They all count the same plate, and the first student counts 98 colonies, the second counts 115 colonies, the third counts 103 colonies, and the fourth counts 93 colonies. The professor te
Help please Darwin theory, guppy spots, bioman! :)
1)Below are two histograms showing guppy coloration in two different streams, Stream North and Stream South. Use these histograms to answer the first two questions. Q1. Which spot brightness level is most heavily represented in Stream North?

In radishes, red and white are the pure-breeding colors, and long and round are the pure-breeding shapes, while the hybrids are purple and oval. The cross of a white oval and a purple oval will produce more a. red l
The following nucleotide sequence is found on the template strand of DNA. What is the amino acid sequence produced by this DNA sequence after there is a transition at the last nucleotide?(Hint: Pay attention to which strand i

The B-globin gene has many alleles. What is the maximum number of different alleles of the B-globin gene that could be carried by 6 children with the same mom and dad given that the parents are heterozygous? A) 4 B) 6 C) 8 D) 12
What is the potential evolutionary consequence of this?
In 1995, Hamilton Smith, Craig Venter and co-workers published the first complete genome sequence of a self-sustaining organism, that of the bacterium Haemophilus influenzae. Analysis of the genome sequence revealed that the organism does not have a
Homozygous or heterozygous for the dominant trait?
Suppose that round ears in guinea pigs is a recessive phenotype. You have just adopted a guinea pig with pointy ears. Using crosses, how can you determine whether this guinea pig with pointy ears is homozygous or heterozygous for the domina
The ability to taste bitterness in certain foods such as green tea or coffee depends on the T allele, which is dominant to non-tasting (tt). Two siblings are born to a set of parents that both find coffee too bitter for their liking, but one of the s
Replication of DNA in early Daphnia embryos is rapid, taking only 5 minutes to replicate all DNA in the genome which consists of 2.1 x 109 bp. While the speed of genome replication is blinding, the movement of DNA polymerases is a slow 50 nucleotides
The following nucleotide sequence is found on the template strand of DNA. What is the amino acid sequence produced by this DNA sequence after there is a transition at the first nucleotide? (Hint: Pay attention to
Identify the mutation, and label the strand with what type of mutation it contains
The DNA sequence of a gene from three independently isolated mutants is given here. In each mutant, identify the mutation, and label the strand with what type of mutation it contains (transition, transversion, insertion, or deletion). (Hint:
Approximately how many copies of this sequence are predicted to occur in the genome?
Specific DNA sequences, which are very short, are hypothesized to be recognized by primase and are found in many places throughout the genome of a symbiotic bacteria of the Rhizobium bacteria. Because the Rhizobium symbiotic genome has 5.3 x 106 bp o
