In the figure, which number produces haploid gametes by mitosis? 1 2 3 4 In the figure, which structure produces haploid spores by meiosis? 1 2 3 4 If four of the original colonists died before they produced offspring, the ratios of genotypes could be quite different in the subsequent generations. This would be an example of diploidy. gene flow, genetic drift. disruptive selection. stabilizing selection. Each of the following questions have a 3.points value: Please use the following information...

For a species with a diploid number of 18, indicate how many chromosome will be present in the somatic nuclei of individuals who are: Haploid Triploid Tetraploid Trisomic Monosomic Autotriploid
. A diploid fish hybridizes with a closely related tetraploid. If the haploid number is 22, how many chromosomes would the hybrids be expected to have? O 11 O 22
Watermelons can have varying ploidies. Ploidy refers to the number of each chromosome present in a somatic cell. For example, most varieties are diploid that contains two copies of each chromosome, while some are tetraploid which contain four copies of each chromosome. Seedless varieties are triploid which have three copies of each chromosome that are present. Armed with the knowledge that seeds are plant embryos that have the potential to become a mature plant (and therefore are comparable to human...
Part A The haploid number for the mosquito is 3, how many chromosomes are found in a member of the species that has one of the following characteristics? Sort these (items) into the proper categories.

1. Represent all chromosomes in a 2n = 4 cell before replication. Number the homologous chromosomes as you would in a karyotype (e.g., Chromosome 1, Chromosome 2). 2. Gene F is on Chromosome 1 and gene G is on Chromosome 2. This cell carries two different alleles of gene F (called F and f), and two different alleles of gene G (called G and g). Label these alleles on the unreplicated chromosomes that you drew above. 3. In the space...
Question 2: The Atlas blue butterfly has 224 homologous pairs of chromosomes. Each pair consists of one chromosome from the butterfly's mother and one from its father. A. Assuming no crossing over, what is the probability that a sperm this butterfly makes has all of the chromosomes from the butterfly's own father? Why? (You do not need to calculate out this number- a number with an exponent is fine.) (roughly 3-4 sentences) B. How many chromosome 17's does this butterfly...
