In a genetic cross between aabbccddee and aabbccddee what fraction of the offspring will be homozygous dominant for all five gen
aniked [119]

Answer:

None

Explanation:

The desired homozygous dominant genotype is AABBCCDDEE. To have an offspring with genotype "AABBCCDDEE", at least one copy of the dominant alleles for the genetic loci should be present in either of the parent. However, both the parents are homozygous recessive for all the five mentioned genetic loci and therefore, cannot have a progeny with homozygous dominant genotype "AABBCCDDEE". All the progeny of a cross between the two parents each with genotype "aabbccddee" would have homozygous recessive for all the give loci.

aabbccddee x  aabbccddee =  All aabbccddee

STatiana [176]

Answer:

a) False.

b) True.

c) False.

d) True.

e) False.

f) True

g) True.

Explanation:

a) The main characteristic of homologous chromosomes is that they have an equal size. There is a difference in size on both chromosomes.

b) In number one, two chromosomes are homologous. In number two also two chromosomes are homologous. On the other hand, the chromosomes at number one and two are different. Each chromosome has two sister chromatids.

c) A DNA molecule has a double helix, that is, two chains. When a DNA chain is broken and a chromatide has a DNA chain, then two chromatids make up a chromosome and a DNA chain, in this way there are eight dsDNA molecules

d) If each chromosome contains a centromere, therefore, there are four centromeres on all four chromosomes.

e) If a chromosome contains four telomeres, therefore there will be sixteen telomeres.

f) The function of cohesin is to regulate the separation of chromatids in the cell division process. When DNA replication is complete, the DNA compacts and condenses to form mitotic chromosomes.

g) The CENPA protein is encoded by the CENPA gene.
