A cross between two plants that both have yellow flowers produces 80 offspring plants, of which 38 have yellow flowers, 22 have

red flowers, and 20 have white flowers. If one assumes that this varia- tion in color is due to inheritance at a single locus, what is the genotype associated with each flower color, and how can you describe the inheritance of flower color?

Always start with the genotypic ratios, because they'll be the same. Since hidden variation is popping out, you can assume that both of the parents are heterozygous. The problems you get will be the F2 ratio of the cross between two homozygous individuals.

1:2:1 is the genotypic ratio for one locus. AA:Aa:aa.

1:2:1 is the phenotypic ratio for incomplete dominance. Incomplete dominance means that the heterozygote expresses differently from either homozygote.

3:1 is the phenotypic ratio for complete dominance.

2:1 is the phenotypic ratio for lethal recessive.

Which of the statements are true? Fats that contain more saturated fatty acid residues than unsaturated fatty acid residues are
Kazeer [188]

Answer:

The best answers to the question: Which of the statements are true? Would be the following:

1. Fats that contain more saturated fatty acid residues than unsaturated fatty acid residues are more likely to be solid at room temperature.

3. Unsaturated fats are more likely than saturated fats to be liquid at room temperature.

5. Triacylglycerols (tryglicerides) are composed of fatty acid residues and glycerol.

Explanation:

The options chosen from the five options are all characteristics of triglycerides. These molecules, which are pretty complex, have all of the options above except for 2 and 4 because these molecules, especially unsaturated fats do not have a high melting point, that is why they remain liquid at room temperature. So that option is wrong. Also, although tryglicerides do have carboxyl groups, chemically speaking they are better categorized as esters.

The condition of having a diploid chromosome complement in which one chromosome lacks its homologous partner is called
kaheart [24]

Answer:

Monosomy

Explanation:

Monosomy is a condition in which there is an absence of one chromosome from the pair of chromosome in an individual's karyotype. The human karyotype consists of 46 chromosome, but in the case of monosomy, which is the absence a chromosome, such individual will possess 45 chromosomes.

Females possess two XX chromosomes, but in the case of monosomy, the female has just one X chromosome instead of two.

Monosomy results to certain human genetic conditions like Turner syndrome.
