you cant just put Dd on a punnet square you have to have two of them like dd,DD or Dd,dd you can also have the same one twice

In a punnet square where the mothers genotype is Dd and the fathers genotype is dd does the mother or the father have dimples?
The mothers will because the father is the dominant.
How many offspring are likely to have recessive traits if the parents are hybrids?
50%. There are four possible outcomes of the cross:dominant trait from "dad", dominant trait from "mom"recessive trait from "dad", dominant trait from "mom"dominant trait from "dad", recessive trait from "mom"recessive trait from "dad", recessive trait from "mom"Therefore, to get hybrid offspring (one dominant, one recessive), you have a 2 out of 4 chance.
What genotype is Dd?
Phenotype is the observed trait. The dominant trait in this case is observed- D
If a homozygous dominant plant crossed with a homozygous recessive plant what is the genotype and phenotype of their offspring?
If two homozygous plants with contrasting traits are crossed, the expected genotypes for the offspring will be heterozygous. The dominant trait would be expressed, but they'd be carriers for the recessive trait.
If 675 plants resulting from the cross display a trait controlled by a dominant allele how many plants will show the trait controlled by the recessive allele?
In a gene loci there can be four combinations of 2 alleles. Suppose these possible allele combinations are called D for dominant and R for Recessive. The possible combinations for two of them are DD, DR, RD and RR. Wherever the D occurs the dominant trait will be displayed. There is only 1 where the recessive trait is displayed and this is the last or RR case. There must be 3 times the number of cases of the dominant trait as the recessive so the recessive trait is displayed in 675 / 3 cases or 225

What does it mean that an organism is homozygous dominant for a trait?
Homozygous Dominant for a trait means that an organism has two dominant alleles for that trait. Here's an example: Trait: Widow's Peak Widow's Peak allele: Dominant (D) No widow's peak allele: Reccessive(d) Homozygous Dominant (DD) Homozygous Reccessive (dd) Heterozygous (Dd)
What is the probability of producing a normal child by two parents who are carriers for an autosomal recessive disorder?
75%. Explanation: if both parents are carriers than their Gametes would be Dd x Dd, resulting in DD (1/4), Dd (2/4), and dd(1/4), meaning that there is a 25% chance that they will have a child that has the disorder. DD = A normal child that lacks the recessive gene, therefore not a carrier Dd = A normal child that carries the recessive gene dd = A child with the disorder + carries the gene, hence the child's future offspring will carry it as well.

What logo has a yellow square with an n in it?
dd
What are the three different combinations of alleles?
If the gene for a trait has two alleles, one dominant (D) and one recessive (d) there are three possible combinations in the genotype: DD (homozygous dominant) Dd (heterozygous) dd (homozygous recessive)
Square root of 64 then cube it?
512.
Three reasons why women pass on sex-linked traits?
== One is that their chromosomes are XX and men are Xy. The Y cannot carry any genetic traits. So if you have D== normal and d=disease and the mom would be Dd, and the dad would be dd, then you write it as... mom = XDXd and dad = Xdy. And the y carried down in the punnet square would mean its a boy, but it would have disease because it only has the little d. If that makes any sense... ==
Is dimple heridity?
Yes. Dimples are dominant. If you have one or two dimples, you have the dominant trait, and your genotype is D-, meaning that we don't know whether you are homozygous dominant or heterozygous for the trait. If you don't have dimples, your genotype is dd, which is homozygous recessive.
Which channel is commonwealth games broadcasted?
DD National (Doordarshan), India's National channel shows a live broadcast of most of the games. Some games can also be seen on DD Sports as well.
