😀Punnett squares help understand how alleles determine traits
👀Dominant alleles are represented by capital letters
🧬Homozygous individuals have two of the same alleles
👶Heterozygous individuals have one dominant and one recessive allele
📊Probability can be calculated to determine the likelihood of specific traits
How do Punnett squares help determine traits?
—Punnett squares show the possible combinations of alleles and help predict the traits that offspring may have.
What is the difference between dominant and recessive alleles?
—Dominant alleles are represented by capital letters and usually determine the physical characteristics, while recessive alleles are represented by lowercase letters.
What is the difference between homozygous and heterozygous individuals?
—Homozygous individuals have two of the same alleles for a trait, while heterozygous individuals have one dominant and one recessive allele.
What is the phenotype?
—The phenotype is the physical characteristics associated with the genotype, such as eye color.
How can probability be calculated to determine specific traits?
—By using Punnett squares and analyzing the possible combinations of alleles, the probability of specific traits in offspring can be determined.
00:01Punnett squares are used to understand how alleles determine traits
01:48Homozygous individuals have two of the same alleles, while heterozygous individuals have one dominant and one recessive allele
02:58The probability of producing offspring with blue eyes in a cross between a homozygous recessive and a heterozygous individual is 50%
05:27Phenotype and genotype ratios can be calculated to determine the likelihood of specific traits in offspring
