Homework Answers
1. Plant cell in anaphase.
Explanation: where in this picture in anaphase stage sister chromatids move towards the opposite pole and the structure look similar as a plant cell because of defined cell shape .
2. when we cross the heterozygous women and homozygous dominant men the probability of heterozygous children would be 1/8 that is 12.5%. where the children exhibiting the heterozygous genotype will have dominant phenotype because in case of complete dominance dominant allele masks the recessive allele.

7. A man with blue eyes and dark hair, whose mother had blond hair, mates with a woman who is homozygous recessive for both traits. a. What is the woman's genotype ddbb b. What is the man's genotype? (hint: keep in mind that His mother had blonde hair, so this helps you figure out his genotype for hair color) Heterozygous C. Figure out what gametes are produced for the man and the woman and fill out the Punnett square (you...

A tomato plant heterozygous for stem color and fasciation (the dominant alleles linked on the same chromosome) is pollinated by a plant heterozygous for stem color and homozygous recessive for fasciation (that is nonfasciated). 29. What alleles will the sperm carry?_ What alleles will the eggs carry? 30. What are the genotypes of the progeny? What are the phenotypes of the progeny? 31. If the dominant alleles for stem color and fasciation are commonly located on the same chromosome, how...

Uption 4. The inheritance of hair and eye color is very complicated. Scientists have found approximately 10-20 genes responsible for determining hair and eye color in humans (sheesh - I thought a dihybrid cross with 2 genes was bad...). Although many genes are involved in producing these phenotypes, it does seem that just a few genes play a major role in determining the color of our hair and eyes. The following is a simplified, but still somewhat realistic view of...
