Homework Answers
1) 2 homologous chromosomes are found in a homologous pair
2) each chromosome is in the duplicated state so each chromosome has 2 sister chromatids so a total of 4 sister chromatids are present.
3) cell cycle progress as G1, S, G2 and M phase. G1, S, G2 are part of interphase so the answer is Interphase.
4) there are 46 chromosomes in a human cell, 22 pairs of autosome and 2 allosomes.
5) No, different species have a different number of chromosomes
6) the total number of chromosomes= 2* number of chromosome pairs
= 2*16
= 32
7) polar bodies are formed during oogenesis.

Please answer genetics questions 9 and 10
The following is the genetics of determination of blood type in human. How many alleles are ever known that are involved in determination of blood type? How many alleles we as individual can we have in our DNA? Is this a typical example of monogenic trait? Digenic trait? Or trigenic trait? Is only one gene involved? Is A dominant over B allele? Is A dominant over O allele? Is B dominant over O...

Inherited traits in humans are determined by materials in specific locations on chromosomes. Each normal human has 23 pairs of chromosomes, one chromosome in each pair coming from each parent. A gene is a portion of each chromosome in a pair. The material which makes up a gene on the pair of chromosome comes in forms called alleles. Each distinct combination of alleles is called a genotype. Consider a gene that has two alleles A and a. Suppose that the...

Practice Using a Punnett Square. Punnett Squares are tools to identify outcomes known genotypes. They can be used to help infer probabilities of genotypes and from a particular cross. of possible crosses between individuals of phenotypes amongst offspring lele forms "A" and "a". A woman is heterozygous, so she can produce eggs with Consider a gene with all 9. and Write them across the top of the Punnett Square below the following...

Agapanthus is a dominant, homozygous lethal trait among Telorites from the planet Teleflora. Subjects with this condition love to send flowers. From a group of Telorites heterozygous at the Agapanthus locus (with two alleles: A = dominant (trait) allele, a = recessive (wild-type) allele), 88% of the Telorites have the Agapanthus phenotype, and 12% look wild-type. Also, true-breeding wild-type Telorites (aa genotype) have 0% penetrance. A Telorite with the Agapanthus phenotype mates with a true-breeding Telorite with the wild-type phenotype....

Human Mendelian Traits Mendelian Traits are those traits which follow Mendel's rules of only 2 possible versions of a gene(1 dominant, 1 recessive). There are only a few examples of this in humans. 1. Circle the heterozygous dominant genotypes: AA Aa aa YyYY W Re RR 2. Circle the homozygous recessive genotypes: AA Aa aa YyYY V ir Rr RR 3. Use the chart below to determine your phenotype (observable characteristic) and possible genotype(s) (a pair or pairs of alleles)....
