likoan [24]
The limitation is that she can't test is on humans for ethical reasons. In order to test this, theoretically, she would need to ask some women to use this cosmetic and compare their fetuses to the fetuses of women who didn't. But this is not likely to be approved by the ethical committee, as causing damage to a fetus is not ethical.

3. Which of the following is an accurate description of mitosis and meiosis? A. Meiosis produces two haploid daughter cells, whi
maria [59]

The correct answer is - B. Mitosis produces two diploid daughter cells, while meiosis produces four haploid daughter cells.

The processes of mitosis and meiosis are often confused with one another, mostly because of the similarity in their names.

The mitosis is a type of cell division where the end result is two daughter cells, each of the cells has the same number and kind of chromosomes as the parent nucleus. Thus is typical for the growth of tissue.

The meiosis is a type of cell division where the end result is four daughter cells, each of the cells having half the number of chromosomes of the parent nucleus. This is typical for the gametes and the plant spores.

A mutation that causes a yellowing of leaves in snapdragon plants was discovered in the early 1900s. Plants with this condition,
Serga [27]
Looking at the second cross, a 2:1 phenotypic ratio (instead of the typical 3:1) usually indicate a lethal homozygous genotype. Based on the question, it’s sensible to assume that a snapdragon homozygous for the aureal allele, which should have a even lesser chlorophyll count than the heterozygote, can’t even make it to the birth of the plant, thus the GAGA type never existed in reality. Under this assumption, we can deduce that the 2/3 aurea is of genotype GAG and the 1/3 green offspring of genotype GG. If a punnet square was pulled including the lethal genotype, it will be easily seen that the aureal allele is the dominant type. The first cross of genotype GG x GG conform to this conclusion. And the third is therefore a test cross between the homozygous recessive GG and the heterozygous GAG (aurea), with the result abiding our theory. Correct me if I was wrong, the GA allele is termed dominant negative as a single copy of it results in a deficit in chlorophyll amount. But anyway, the explanation above should give you an answer to the relationship between the G and GA allele.
