1. There is a 50% probability that a gamete will get a dominant allele
2. Gene pairs segregate independently of others genes in the games formation
3. Allele pairs separate in gamete formation
4. The laws of probability determine the gamete formation
Allele pairs separate in gamete formation
1. Has a phenotypic ratio of 3:1
2. Is the result of the self-fertilization or crossing of F1 individuals
3. Can be used to determine the genotype of individuals with the dominant phenotype
4. Has a phenotypic ratio that equals its genotypic ratio
Is the result of the self-fertilization or crossing of F1 individuals
1. Four
2. Eight
3. Five
4. Nine
Nine
1. The alleles are dominant
2. One parent must have been homozygous recessive
3. The dominant phenotype parent was a heterozygote
4. The alleles segregated independently
The dominant phenotype parent was a heterozygote
1. Are individual by solid symbols on a faily pedigree
2. Are involved in consanguineous matings
3. Will produce children with the disease
4. Are heterozygotes for the gene that can cause the disorder
Are heterozygotes for the gene that can cause the disorder
1. The phenotype found most commonly in nature
2. The dominant allele
3. Designated by a small letter if it is recessive or a capital letter if it is dominant
4. Your basic party animal
