What is main difference between monohybrid and dihybrid cross? Describe the activity of chromosomes in each stage of meiosis 1 and meiosis 2. How does the number of chromosomes in a parent cell compare with the number of chromosomes in a daughter cell? Why is this important? Explain the ...
What does it mean if a gene is said to be dominant? What is the difference between dominant mutation and recessive mutation? Describe how to identify each of them from a cross that is given P, F_1, and F_2. What is the difference between a gene and an allele? Provide a specific ...
As with mitosis, DNA replicates prior to gamete formation in meiosis. However, thecell divides twiceto producehaploiddaughter cells. When haploid sperm and egg combine at fertilization, a normaldiploidzygote forms. Nondisjunction may occur during the first division (meiosis I) when homologous chromosom...
What is a monohybrid cross and a dihybrid cross? What is the opposite of autosomal recessive? What does autosomal co-dominant mean? What is a Punnett square with the father with genotype of XcY and the mother of genotype XcX? What is the heterozygote of an autosomal recessive condition calle...
What does it mean if a mutation is dominant or recessive? What is the heterozygote of an autosomal recessive condition called? What would the genotype ratio of the offspring be for two individuals that are heterozygous? In ...
What is a dihybrid cross and what does the 9:3:3:1 ratio mean? How do the two correlate with each other? a. What are monohybrid crosses? b. How are monohybrid crosses performed? c. What is the outcome of the F1 generation? d. What is dominant and recessive? Can we expect a 9...
1. What does it mean to say that two genes are linked? 2. Can linked genes assort independently? Why or why not? What are the potential offspring from a mating between two heterozygous individuals? How do scientists apply Mendelian genetics to predict the phenotype of genetic crosses?...
What is the resultant ratio of phenotypes of offspring produced by the dihybrid cross of heterozygous parents? What is the heterozygote of an autosomal recessive condition called? How do recessive alleles remain in a population? How frequently are mutations produced in a gene pool? How does mu...
What does it mean if a gene is said to be dominant? 16% of a population is homozygous recessive for a trait. What are the frequencies for the dominant and recessive alleles of that trait? Explain the relationship between alleles, genes, chromosomes, and dominant and recessive traits. What ...
